One of the "Last Great Places" in the Western Hemisphere, as declared by the Nature Conservancy, Block Island has done a great job at preserving its natural beauty, with 40% of its territory being devoted to wildlife refuges.

32 miles of coastline and inland trails, along with beaches, biking, and trekking provide ample opportunities for enjoying the great outdoors. And, when the sun goes down, a healthy scene of bars and restaurants with an easy-going atmosphere and great food welcomes visitors.

Colorado is not just about ski resorts and mountains, as Alamosa proudly demonstrates. If you head down south in the Centennial State you will find this high-altitude agricultural community mainly known to UFO sightings chasers and birdwatchers.

The town, packed with antique shops and craft breweries, is near the Great Sand Dunes National Park, a surreal place that makes visitors feel as if they were in the Sahara desert. The San Luis Valley and the Sangre de Cristo mountains, also near, provide ideal spots for hiking and exploring during the summer months.

Ice Age Trail, Wisconsin

Hiking trails might not look like the most crowded places but they can be—the popular ones, at least. Wisconsin’s Ice Age Trail offers 1,200 miles of scenic hiking paths without the heavy foot traffic of places of most known trails.

The trail can be thoroughly enjoyed without the need to traverse it in full, as it has many segments that can be discovered individually. Wooded hills, gorgeous glacial lakes, and plenty of trailside camps and small communities to rest make this trail a great spot for a holiday in nature.

There is much more to Massachusetts than Boston, Cape Cod, and the Berkshires—for example, the Pioneer Valley . Carved by the Connecticut River, this peaceful area is home to several vintage mill cities turned into modern towns full of restaurants and one-off shops.

Hikers can walk the north woods on the New England Trail and Springfield visitors can discover the Naismith Memorial Basketball Hall of Fame, where the sport was born in 1891, as well as the Amazing World of Dr. Seuss Museum & Sculpture Garden.

John Day Region, Oregon

While it has managed to avoid massive crowds for all of its existence, it's hard to believe that a natural wonder as picturesque as John Day Region will remain a calm place for much longer in this day and age. Take a moment to Google-search John Day Region’ s Painted Hills and you will get the idea.

And if that is not enough reason to make you plan a visit, the region is packed with old-growth rainforests, canyons, high desert plains, and undammed rivers complete with sandy beaches and gorgeous meadows, all in an easy-to-move-around area.

Pennsylvania Wilds

When considering the abundance of wildlife and untamed mountain creeks, ancient trees of the Forest Cathedral, and Pine Creek’s own version of the Grand Canyon, it becomes clear that the Pennsylvania Wilds is a region that lives up to its name.

Sprawling across a vast expanse of the rugged Allegheny Plateau, the region boasts 29 state parks, two national wild and scenic rivers, a world-class stargazing center at Cherry Springs, and human relics like the Kinzua Bridge.

Tulsa, Oklahoma

Image: Drew Harbour

A city that has a ton of amazing things to offer but never appears on those glamorous Top-Cities-To-Visit lists, Tulsa is a hidden jewel of the Midwest. Its beautiful Art Deco architecture, impressive museums and cultural institutions with collections rivaling those of major cities, lively music scene, and craft breweries make it a great long weekend destination.

The best time window to visit would be from September to November when the temperate weather is ideal for walking tours and bike rides in the historic neighborhoods. The Tulsa International Airport has nonstop flights from all over the country, all year long.

Combining beach fun and outdoor adventure with copious wildlife, Cumberland Island National Seashore receives visits that usually stay for the day. But staying overnight at beachside campgrounds or the Greyfield Inn is a fun adventure as well.

Georgia’s largest and southernmost barrier island is full of wild horses, sea turtles, wild turkeys, and infinite birds everywhere to be seen along the island’s 18-mile-long beach.

Western Tennessee

Image: Joshua J. Cotten

An enticing blend of nature, history, music, and food tells us that there is so much more to Tennessee than the tourist magnet that is Nashville. From the cradle of blues, soul, and rock ‘n’ roll that is Memphis to the historical sites of Shiloh National Military Park and Fort Donelson National Battlefield to the Meeman-Shelby Forest State Park that conserves nearly 13,000 acres of rare hardwood bottomland along the Mississippi River, including eerie bald cypress swamp. Western Tennessee is a place to explore.

10

Ouachita Mountains, Arkansas

Image: Oliver Graham

The few visitors who venture past Hot Springs National Park, and into the highlands of west-central Arkansas are rewarded with a haven of solitude and natural wonder in the form of the Ouachita range.

These mountains are ideal for those who like their hiking, camping, and fishing in a peaceful environment. And, if that proves to be too calm, Magazine Mountain is a regional hang-gliding mecca that also boasts amazing mountain biking routes.

Tiger salamander

Image: Anastasia Pirri

Meet the tiger salamander—one of the largest terrestrial salamanders in North America. While its size is certainly impressive, the tiger salamander also has other traits that make it stand out. Take its appearance, for example: its dark brown body with bright yellow blotches resembles tiger stripes, which is why it has such a peculiar name. But there's more! Unlike many other salamanders, this one spends much of its time underground, using its large, powerful limbs to dig.

Fun fact: Some states, like Colorado and Kansas, have named it their official state amphibian!

2

Eastern Hellbender

Image: laura adai

Although the tiger salamander is impressively large, another salamander stands out for its huge size: the Eastern Hellbender.

Cryptobranchus alleganiensis alleganiensis is its scientific name (quite a mouthful, right?). It holds the title of the largest salamander in North America. In fact, it's sometimes nicknamed "snot otter" due to its large body and the slippery texture of its skin.

Amphiuma

Image: Wolfgang Hasselmann

When you first see this creature, you might mistake it for a snake or an eel. But it's actually an amphibian—more specifically, an aquatic salamander known as the amphiuma. Its appearance, let’s just say, isn’t exactly what most would call "cute."

This unusual amphibian can grow up to 3 feet long! And while not immediately noticeable, it has tiny legs with only one, two, or three toes, depending on the species. Its limbs aren't very useful, but they do make the amphiuma look just a bit creepier.

4

Colorado River Toad

Image: Crystal McClernon

The Colorado River Toad may not be the cutest or most dazzling creature out there, but it's certainly one of the most fascinating. Native to the southwestern United States, this amphibian is one of the largest toads in North America, but what sets it apart isn't its size. So, while it may look slow and harmless, this toad is capable of releasing a dangerous, highly psychoactive toxin that acts as a defense mechanism and can be fatal to many species, including dogs.

5

Common Mudpuppy

Now, it's time for an amphibian whose cuteness is one of its most distinctive features; even its name reflects that! We're talking about the Common Mudpuppy, an aquatic salamander that inhabits streams, rivers, ponds, and lakes. It's also one of the few salamanders that remain fully aquatic throughout their entire life. And that’s precisely why it sports a pair of large, red external gills on the sides of its head, giving it an almost 16th-century European look!

6

Gray Tree Frog

Image: Aurora K

The small Gray Tree Frog inhabits the forests and woodlands of the eastern United States. And while it's true you might find it on trees and plants, its nickname isn't entirely accurate when it comes to color. Yes, it can be gray, but this amphibian has the ability to change its color to blend in with its surroundings! It also has another superpower: the ability to survive freezing temperatures. By producing a natural antifreeze, it protects its organs during cold conditions that most of us couldn’t begin to handle.

7

Spotted Salamander

Image: Kristina Kutleša

As its name suggests, what distinguishes the Spotted Salamander is its shocking look. But beware, its mottled appearance isn't just for show. It also acts as a warning to ward off predators! If you've ever seen one in the wild, consider yourself lucky because although it’s fairly widespread, this salamander spends most of its time underground.

Pacific Giant Salamander

Image: wallace Henry

If you venture into the mountainous regions of the Pacific Northwest, you might come face-to-face with the Pacific Giant Salamander, one of the largest terrestrial salamanders in North America.

Reaching up to 14 inches in length, this amphibian is striking to see—but it’s even more surprising when you hear it. That’s right: unlike most of its kind, the Pacific giant salamander can make audible barking sounds!

Barking Tree Frog

Image: José M. Alarcón

We have a contestant that could go head-to-head with the Pacific Giant Salamander in a barking contest: the aptly named Barking Tree Frog.

Let’s just say the frog’s striking features are perfectly summed up by its name. In states like Florida, Georgia, and South Carolina, you can find this little amphibian calling from the treetops or near freshwater shores.

10

Dusky Gopher Frog

Image: Geraldine Dukes

Finally, we have the most mysterious and elusive of all: the Dusky Gopher Frog. As one of the rarest frog species in the U.S., the Dusky Gopher Frog is incredibly elusive and critically endangered, with fewer than 200 individuals left in the wild. The dusky frog spends most of its life hidden underground and only comes out during the mating season.

Yellowstone National Park, created in 1872, is a vast natural forest of 3,500 square miles that spans the states of Wyoming, Montana, and Idaho. More than half of the world's geothermal phenomena can be observed here , with some 10,000 different examples. It also has more than 300 geysers, which is about two-thirds of all the geysers on the planet.

This location, the first national park in the United States, has been a World Heritage Site since 1978. It is also known for protecting abundant and diverse wildlife —such as grizzly bears, wolves, bison, and wapiti— and for drawing millions of visitors from all over the world each year. And you, have you ever been?

The Independence Hall, located in historic Philadelphia, was designated a World Heritage Site in 1979. This location, far more than just a building, is considered the birthplace of America’s political foundation . The Assembly Room of the Pennsylvania State House, now known as Independence Hall, is where the Declaration of Independence was signed in 1776. And just 11 years later, the United States Constitution was also debated and signed here.

This Georgian-style red brick structure was designed by Scottish lawyer Andrew Hamilton and completed in 1753 to house the colonial assembly of the Province of Pennsylvania. In the 19th and 20th centuries, it was then renovated several times. In 1966, the building was recognized as a National Historic Landmark by the U.S. government and is currently the centerpiece of the Independence National Historical Park.

Statue of Liberty

Image: Anthony DELANOIX

Installed in 1886 at the gate of New York’s harbor, the Statue of Liberty has since welcomed millions of immigrants who have come to populate the United States. This colossal neoclassical 305-foot-tall effigy enlightening the world with its torch was made in Paris by the sculptor Frédéric Auguste Bartholdi in collaboration with Gustave Eiffel. It was a gift from France to our country on the occasion of the centenary of our independence.

To visit this historic monument, declared a UNESCO World Heritage Site in 1984, tickets must be purchased in advance. Or you can always ride the fare-free Staten Island ferry and admire it from afar in all its splendor!

Located in the southwest of Colorado, the Mesa Verde Plateau reaches an altitude of over 8,500 feet. The National Park was established in 1906 and was added to the list of American World Heritage Sites in 1978. This location hosts a large number of Pueblo Indian dwellings built between the 6th and 12th centuries. Some 4,400 settlements have been found , including villages built high up on the plateau and imposing stone-built homes on rocky outcrops, with more than a hundred rooms in some cases.

The Mesa Verde National Park, which nowadays protects these invaluable archaeological sites, is a testament to the ancient cultural traditions of Native American tribes and is among the best preserved in the United States. If you haven’t visited yet, you must! We guarantee you a spectacular window into the past!

Hawaii Volcanoes National Park is located on the southernmost Hawaiian island and was founded in 1916. It is best known for its extraordinary biodiversity spread over more than 340,000 acres, and it is in fact thanks to this natural richness that UNESCO declared it a World Heritage Site in 1987.

The park, as you would have guessed, is home to several volcanoes . Although many of them are currently inactive, two are very much alive: Mauna Loa , which last erupted in 1984, is known to be still active and is considered the world's greatest volcanic mass; Kīlauea is more than 200,000 years old and has been erupting since 1983, the most recent occurring on June 3, 2024.

If you are considering visiting the park, exploring the volcanoes, and enjoying a unique experience, we also recommend a museum tour , where you can learn all about the history of these fascinating fiery peaks.

Monticello and the University of Virginia

Image: Richard Hedrick

The Monticello Residence in Virginia, designed by Thomas Jefferson, the third president of the United States, is one of the finest examples of American neoclassical architecture . Since 1987, it has been on the UNESCO World Heritage List, along with the University of Virginia in Charlottesville.

Jefferson created Monticello as his plantation mansion and envisioned the university as the ideal ‘academic village’ . His vision of architecture, based on classical antiquity, reflects not only his aspirations for a new American republic heir to the European tradition but also the degree of cultural experimentation that could be expected of a country in the process of democratic evolution.

Papahānaumokuākea, made up of a series of 583,000 square miles of small islands, atolls, and surrounding marine wilderness, is located in northwest Hawaii. This particular location has enormous natural value as one of the largest marine protected areas in the world . It is equally important for its Native culture. Two of its islands, Nihoa and Makumanamana , bear archaeological remains that attest to the presence of human settlement even before the arrival of Europeans . For Hawaiians, this site has cosmological significance , as it represents the bond between humans and nature.

Papahānaumokuākea was designated a World Heritage Site in 2010, and although it’s not currently open to the general public, it continues to be accessible for research, habitat restoration, and cultural and educational purposes.

Grand Canyon National Park is known as one of the seven natural wonders of the world and has been a UNESCO World Heritage Site since 1979.

Located in the state of Arizona, this park is divided by a gigantic steep-sided canyon carved by the Colorado River, which, at more than 6,000 feet deep, is the most spectacular gorge in the world . This site is so relevant that all the geological history of the last two billion years can be found in its horizontal strata. And across its 277 miles, there are even traces of prehistoric man's efforts to adapt to a particularly inhospitable environment .

If you haven’t visited it yet, you should soon join the more than 5 million people traveling each year!

San Antonio Missions

Image: USA-Reiseblogger

This 2015 World Heritage Site, built on what was once the border of New Spain along the San Antonio River, constitutes five mission complexes that reflect the history of the region.

Founded by Franciscan missionaries in the 18th century, San Antonio includes architectural structures, archaeological remains, churches, dwellings, farmland, silos and water supply systems .

This site, located in Texas, is a living testament to the Hispanic monarchy's enterprise to colonize, evangelize, and defend the northern frontier territories of New Spain. These missions are also an example of the mixture of Hispanic and Coahuila culture , as can be seen in the ornamental elements of the churches that mix Catholic symbolism with native naturalist aesthetics.

The 20th-Century Architecture of Frank Lloyd Wright

Image: Yuhan Du

This series of eight Frank Lloyd Wright works recognizes the famous architect's influence on modern design . The most relevant buildings included in the 2019 Unesco designation are Fallingwater House in Mill Run, Pennsylvania; Unity Temple Church in Oak Park, Illinois; Herbert and Katherine Jacobs House in Madison, Wisconsin; and the Solomon R. Guggenheim Museum of Art in New York City, among others.

These sites are a great example of the ‘organic architecture’ conceived by Wright, characterized by open plan design, the blurring of the boundaries between inside and outside, and the highly original use of materials such as steel and concrete . Wright's innovative conception of architecture, whether in residential, work, cultural, or religious buildings, greatly influenced the evolution of modern architecture in Europe and the United States and is still a point of reference for designers today.
