Yellowstone National Park: The World’s First National Park and a Geothermal Wonderland
Yellowstone National Park holds a sacred place in the history of conservation—it was established in 1872 as the world’s first national park, a groundbreaking decision that set a precedent for protecting natural landscapes worldwide. Spanning parts of Wyoming, Montana, and Idaho, Yellowstone is not just a park but a geological marvel, sitting atop one of the largest active volcanoes on Earth. This volcanic activity is responsible for the park’s most iconic feature: its abundance of geothermal phenomena, which paint the landscape in vivid hues of blue, green, orange, and yellow, creating otherworldly scenes that feel like they belong on another planet.
The star of Yellowstone’s geothermal show is undoubtedly Old Faithful, a geyser that has earned its name for its remarkable predictability. Erupting roughly every 90 minutes (give or take 10 minutes), Old Faithful shoots a column of superheated water and steam up to 185 feet into the air, drawing crowds of eager onlookers who gather around its basin to witness the spectacle. But Old Faithful is just one of over 10,000 geothermal features in the park, which include hot springs, mud pots, fumaroles, and other geysers. Among these, the Grand Prismatic Spring stands out as a true masterpiece. As the largest hot spring in the United States and the third-largest in the world, its vibrant colors are a result of heat-loving bacteria that thrive in its waters. From above—best viewed from the overlook trail—the spring resembles a giant rainbow, with a deep blue center (where the water is hottest, reaching up to 188°F) fading into brilliant shades of green, yellow, and orange at the edges, where temperatures are cooler.
Beyond its geothermal wonders, Yellowstone is a haven for wildlife, boasting one of the most intact temperate ecosystems on the planet. The park is home to the “Big Five” North American mammals: grizzly bears, black bears, wolves, bison, and elk, along with a host of other species including coyotes, foxes, pronghorn, bighorn sheep, and numerous bird species. For wildlife enthusiasts, early mornings and late evenings are the best times to spot these animals, particularly in areas like Hayden Valley (a prime spot for bison herds and wolf sightings) and Lamar Valley, often referred to as “America’s Serengeti” for its high concentration of wildlife.
When it comes to outdoor activities, Yellowstone offers something for every season and skill level. Hiking is one of the most popular ways to explore the park, with over 900 miles of trails ranging from easy boardwalk loops around geothermal features (like the Midway Geyser Basin Trail, which leads to the Grand Prismatic Spring) to challenging backcountry treks that take hikers deep into the park’s wilderness. Camping is another beloved activity, with 12 campgrounds offering over 2,000 sites—from primitive backcountry campsites for experienced backpackers to developed campgrounds with amenities like restrooms and picnic tables for families. Birdwatching is a year-round pursuit, with over 300 bird species recorded in the park, including bald eagles, ospreys, and the elusive harlequin duck. In winter, Yellowstone transforms into a winter wonderland, with snowshoeing, cross-country skiing, and snowmobile tours (in designated areas) allowing visitors to experience the park’s geothermal features dusted in snow—a truly magical sight.
Grand Canyon National Park: A Monument to Time and the Power of Water
If Yellowstone is a showcase of geothermal power, Grand Canyon National Park is a testament to the slow, relentless force of water and the passage of time. Carved over millions of years by the Colorado River, the Grand Canyon stretches for 277 miles, reaches a width of up to 18 miles, and plunges to a depth of over a mile, making it one of the most awe-inspiring geological formations on Earth. Located in northern Arizona, the park attracts millions of visitors each year, all eager to stand at the edge of the canyon and gaze out at the layers of rock that tell a story of Earth’s history spanning over 2 billion years.
What makes the Grand Canyon truly unforgettable is its sheer scale and the ever-changing beauty of its landscape, especially during sunrise and sunset. At dawn, the first rays of sunlight paint the canyon’s red, orange, and gold rock layers in warm, glowing hues, turning the vast expanse into a living canvas. As the sun sets, the colors deepen, with shadows stretching across the canyon’s ridges and valleys, creating a dramatic, almost surreal scene that leaves visitors speechless. The South Rim, the most accessible and popular part of the park, offers numerous overlooks—including Mather Point, Bright Angel Lodge, and Hopi Point (a favorite for sunsets)—where visitors can take in these breathtaking views. The North Rim, which is higher in elevation and less crowded, offers a different perspective, with cooler temperatures and lush forests framing the canyon’s edge.
For those who want to go beyond viewing the canyon from the rim and experience its depths firsthand, there are plenty of adventurous activities to choose from. One of the most iconic experiences is hiking down to the canyon floor. The Bright Angel Trail and the South Kaibab Trail are the two main trails that lead from the South Rim to the bottom, where the Colorado River flows. These hikes are not for the faint of heart—they are strenuous, with steep descents (and even steeper ascents on the way back up) and extreme temperatures, especially in summer. Most hikers take two to three days to complete the round trip, staying overnight at Phantom Ranch, a historic lodge located at the bottom of the canyon. For those who prefer a more leisurely way to explore the canyon floor, riding a mule is a classic option. Mule trips to the bottom (and back up) have been offered in the Grand Canyon for over a century, allowing visitors to sit back, relax, and take in the scenery while experienced guides lead the way.
For those who want to see the canyon from a different angle, helicopter tours offer a bird’s-eye view of the vast expanse, highlighting the canyon’s winding rivers, towering rock formations, and hidden valleys. Another thrilling way to experience the Colorado River’s role in shaping the canyon is through white-water rafting. Rafting trips range from half-day excursions on the calmer sections of the river to multi-day expeditions that take rafters through the heart of the canyon, camping along the riverbanks and exploring remote side canyons that are only accessible by water. These trips not only offer an adrenaline rush but also a unique perspective on the canyon’s geology and ecology, as guides share insights into the river’s history and the plants and animals that call the canyon home.
Yosemite National Park: Granite Giants, Thundering Waterfalls, and Alpine Meadows
Yosemite National Park, located in the Sierra Nevada Mountains of California, is a paradise for nature lovers and outdoor adventurers alike. Renowned for its towering granite cliffs, thundering waterfalls, ancient redwood forests, and lush alpine meadows, Yosemite has inspired artists, photographers, and conservationists for over a century—most notably John Muir, the “Father of the National Parks,” who played a key role in convincing President Theodore Roosevelt to protect the area as a national park in 1890. Today, Yosemite draws over 4 million visitors each year, all eager to experience its natural beauty and outdoor adventures.
At the heart of Yosemite’s landscape are its granite formations, which were shaped by glaciers during the last Ice Age. The most famous of these is Half Dome, a massive granite dome that rises 8,842 feet above sea level and is one of the most recognizable landmarks in the United States. For hikers, reaching the top of Half Dome is a bucket-list achievement—it requires a strenuous 16-mile round-trip hike that includes a steep ascent up the subdome and a final climb up cables to the summit, where hikers are rewarded with panoramic views of the Yosemite Valley, the High Sierra, and the surrounding forests. Another iconic granite formation is El Capitan, a 3,000-foot-tall vertical cliff that is considered one of the best rock-climbing destinations in the world. Each year, elite climbers from around the globe come to Yosemite to attempt to scale El Capitan’s sheer face, with some taking several days to complete the climb (sleeping in portable hammocks attached to the rock).
Yosemite is also famous for its waterfalls, which are at their most spectacular in spring, when snowmelt from the Sierra Nevada Mountains feeds the rivers and streams, creating thundering cascades. The Yosemite Falls—the tallest waterfall in North America, with a total drop of 2,425 feet—is the park’s most famous waterfall. It consists of three parts: the Upper Yosemite Fall (1,430 feet), the Middle Cascades (675 feet), and the Lower Yosemite Fall (320 feet). Visitors can hike to the base of the Lower Yosemite Fall via an easy, paved trail, or take the more challenging Mist Trail to the top of the Upper Yosemite Fall, where they can feel the mist on their faces and hear the roar of the water. Other notable waterfalls in Yosemite include Bridalveil Fall (a delicate, 620-foot-tall waterfall that is often the first one visitors see when entering the Yosemite Valley) and Vernal Fall (a 317-foot-tall waterfall that is a popular stop on the Mist Trail).
Beyond its granite cliffs and waterfalls, Yosemite is home to diverse ecosystems, from ancient giant sequoia forests to high-altitude alpine meadows. The Mariposa Grove of Giant Sequoias, located in the southern part of the park, is one of the largest and most accessible groves of giant sequoias in the world. These trees, which can live for over 3,000 years and grow to heights of over 200 feet, are among the largest living organisms on Earth. Walking among these ancient giants is a humbling experience, reminding visitors of the longevity and resilience of nature. In the summer, the park’s alpine meadows—like Tuolumne Meadows, located at an elevation of 8,600 feet—burst into bloom with wildflowers, including lupines, Indian paintbrushes, and daisies, creating a vibrant carpet of color against the backdrop of the granite peaks.
Yosemite offers a wide range of outdoor activities to suit every interest and skill level. Hiking is one of the most popular activities, with trails ranging from easy nature walks in the Yosemite Valley to multi-day backpacking trips in the High Sierra. The Mist Trail, which leads to Vernal Fall and Nevada Fall, is one of the park’s most popular hikes, offering stunning views of the waterfalls and the Yosemite Valley. Rock climbing is another major draw, with hundreds of climbing routes ranging from beginner-friendly crags to challenging big walls like El Capitan. Photography is a beloved pastime in Yosemite, with endless opportunities to capture the park’s beauty—from sunrise over Half Dome to sunset over the Yosemite Valley, and from the starry skies of the High Sierra to the vibrant fall foliage of the lower elevations. In winter, Yosemite transforms into a winter playground, with Badger Pass Ski Area offering skiing and snowboarding, and snowshoeing and cross-country skiing trails winding through the snow-covered forests and meadows.
Zion National Park: Red Rock Canyons and Thrilling Slot Canyon Hikes
Zion National Park, located in southwestern Utah, is a land of dramatic red, orange, and yellow sandstone cliffs, narrow slot canyons, and winding rivers—a landscape that feels both rugged and delicate. Established as a national park in 1919, Zion is known for its unique geology, which is dominated by Navajo Sandstone, a type of rock that was formed over 200 million years ago from sand dunes deposited by ancient deserts. Over time, water and wind eroded the sandstone, creating the park’s iconic canyons, mesas, and buttes.
One of Zion’s most famous features is the Narrows, a narrow slot canyon that is carved by the Virgin River. The Narrows is one of the most popular hikes in the park, and for good reason—it offers a one-of-a-kind experience of walking through a canyon that is sometimes only 20 to 30 feet wide, with towering sandstone walls rising hundreds of feet above. The hike through the Narrows is a water hike, meaning visitors wade through the Virgin River for most of the trail, with water depths ranging from a few inches to several feet (depending on the season and recent rainfall). Hikers must wear special gear—including neoprene socks, water shoes, and sometimes a walking stick—to navigate the slippery rocks and cold water, but the effort is well worth it. Along the way, they are treated to stunning views of the sandstone walls, which glow red and orange in the sunlight, and the clear, cool water of the Virgin River, which is home to trout and other aquatic life.
Another iconic hike in Zion is the Angels Landing Trail, a strenuous but rewarding trail that leads to the top of Angels Landing, a narrow, 1,488-foot-tall rock formation that offers panoramic views of the Zion Canyon. The trail is 5.4 miles round-trip and includes a steep ascent up switchbacks (known as Walter’s Wiggles) and a final stretch along a narrow ridge with drop-offs on both sides. To help hikers navigate this challenging section, the park has installed chains that visitors can hold onto for support. Reaching the top of Angels Landing is a thrilling achievement, and the views—of the Zion Canyon below, the Virgin River winding through the valley, and the surrounding sandstone peaks—are nothing short of breathtaking.
In addition to hiking, Zion National Park offers a range of other outdoor activities. Rock climbing is a popular pursuit, with hundreds of climbing routes on the park’s sandstone cliffs. The park’s cliffs are known for their unique features, including cracks, ledges, and overhangs, which make them ideal for both traditional and sport climbing. Mountain biking is another great way to explore the park, with several designated bike trails, including the Pa’rus Trail, a paved trail that runs along the Virgin River and offers views of the Zion Canyon. For those who prefer a more leisurely experience, driving along the Zion Canyon Scenic Drive is a must. This 6-mile road winds through the Zion Canyon, passing by iconic landmarks like the Great White Throne, the Court of the Patriarchs, and the Towers of the Virgin, and offers numerous pull-offs where visitors can stop and take in the views.
Glacier National Park: Alpine Lakes, Glacial Peaks, and the Going-to-the-Sun Road
Glacier National Park, located in northwestern Montana, is a land of rugged mountains, crystal-clear alpine lakes, and ancient glaciers—a landscape that feels like a step back in time. Established as a national park in 1910, Glacier is often referred to as the “Crown of the Continent” for its stunning beauty and ecological importance. The park is part of the larger Waterton-Glacier International Peace Park, a UNESCO World Heritage Site that straddles the border between the United States and Canada, and is home to one of the most intact ecosystems in North America.
One of Glacier’s most famous features is the Going-to-the-Sun Road, a 50-mile-long scenic road that winds through the park, crossing the Continental Divide at Logan Pass (elevation 6,646 feet). The road is considered one of the most beautiful drives in the world, offering stunning views of the park’s glacial peaks, alpine meadows, and turquoise lakes. Construction of the Going-to-the-Sun Road began in 1921 and took 11 years to complete, a remarkable engineering feat given the challenging terrain. The road is only open during the summer months (usually from late June to early October), as heavy snowfall closes it during the winter. Driving the Going-to-the-Sun Road is an adventure in itself, with hairpin turns, narrow lanes, and spectacular overlooks—including Logan Pass, which is the highest point on the road and a popular spot for hiking and wildlife viewing.
Glacier National Park is also famous for its glaciers, which are the remnants of the last Ice Age. At the time of the park’s establishment in 1910, there were an estimated 150 glaciers in the park. Today, due to climate change, that number has dropped to fewer than 30, and many of the remaining glaciers are shrinking at an alarming rate. Scientists predict that if current trends continue, most of Glacier’s glaciers could disappear within the next few decades. This makes visiting Glacier National Park a urgent and important experience—an opportunity to see these ancient natural wonders before they are gone forever. Some of the most notable glaciers in the park include the Grinnell Glacier, the Sperry Glacier, and the Jackson Glacier, all of which are accessible via hiking trails.
Hiking is one of the most popular activities in Glacier National Park, with over 700 miles of trails ranging from easy nature walks to challenging backcountry treks. The Grinnell Glacier Trail is one
