The crown jewel for many adventurers is Longs Peak, a 14,259-foot mountain whose Keyhole Route—though non-technical—still involves exposure, route-finding challenges, and an exhausting 15-mile round trip with over 5,000 feet of elevation gain. Technical climbers flock to the Diamond, a 900-foot sheer east face of Longs Peak offering some of the most difficult alpine big wall routes in the country. The Continental Divide Trail runs through the park, allowing for multi-day high-altitude backpacking trips with panoramic views of alpine lakes and rugged peaks. Winter brings opportunities for ice climbing in Glacier Gorge and Hidden Falls, plus challenging backcountry skiing in avalanche-prone terrain that demands proper training and equipment.
Denali National Park: Wilderness Expeditions and Summits
Alaska’s Denali National Park represents the ultimate wilderness adventure experience, anchored by North America’s highest peak—Denali, towering at 20,310 feet. Climbing Denali is a serious expedition requiring weeks of commitment, technical mountaineering skills, and the ability to endure extreme conditions, including temperatures dropping to -40°F and sudden severe storms. Beyond the mountain itself, the park offers true wilderness backpacking with no trails, requiring advanced navigation skills and bear safety knowledge as adventurers make their own routes through unmarked terrain. Packrafting combines backpacking with river travel, allowing adventurers to cross otherwise impassable waterways and experience remote valleys rarely visited by humans. Winter brings opportunities for extreme cold-weather camping, dog mushing, and cross-country skiing across a landscape transformed by snow and ice, where temperatures can plummet to -50°F and the northern lights dance overhead.
Canyonlands National Park: Remote Desert Challenges
Utah’s Canyonlands National Park offers some of the most remote and challenging desert terrain in the national park system, divided into distinct districts by the confluence of the Green and Colorado Rivers. The Maze district represents the park’s most challenging area, with a labyrinth of twisting canyons requiring serious four-wheel-drive vehicles just to reach the trailheads, followed by complex navigation through unmarked routes where rangers warn visitors they must be self-sufficient and prepared for emergencies. Mountain biking enthusiasts tackle the famous White Rim Road, a 100-mile loop through the Island in the Sky district that requires 3-4 days to complete while negotiating steep, technical sections with limited water sources. The rivers themselves offer multi-day flatwater paddling expeditions through spectacular scenery, while technical canyoneering routes like Lower Black Box demand advanced skills to navigate narrow slots with swimming sections and rappels. Winter brings special challenges, as temperatures can plummet below freezing, creating treacherous ice on exposed slickrock sections.
Hawaii Volcanoes National Park: Volcanic Exploration
Hawaii Volcanoes National Park offers adventure seekers the rare opportunity to witness the raw power of Earth’s geological forces up close, with the active volcanoes Kīlauea and Mauna Loa creating an ever-changing landscape of lava flows, steam vents, and newly formed land. Adventurous hikers can undertake the challenging 8-mile round trip trek across the floor of Kīlauea Iki Crater, walking on hardened lava that was a seething lake of molten rock in 1959 and still steams in places as moisture hits hot rocks below the surface. The most ambitious backpacking route is the multi-day Mauna Loa Summit Trail, which climbs 6,662 feet in elevation over 19.6 miles to reach the summit of one of the world’s largest active volcanoes at 13,677 feet, where hikers might witness the glow of distant lava against the night sky. Conditions can change rapidly due to volcanic activity, with areas opening and closing based on current eruptions, gas levels, and the creation of new lava flows that sometimes reach the ocean in spectacular steam explosions.
Wind Cave National Park: Underground Exploration
South Dakota’s Wind Cave National Park offers adventure seekers a different dimension of exploration—downward into one of the world’s most complex cave systems, currently mapped at over 150 miles of passages with more discovered each year. The Wild Cave Tour takes properly equipped adventurers on a challenging four-hour journey through undeveloped sections of the cave, where participants must squeeze through narrow passages as tight as 8-10 inches, crawl through tunnels, and climb over rock obstacles while learning about the cave’s unique boxwork formations, which are among the finest in the world. Above ground, the park protects one of the few remaining mixed-grass prairies in the United States, where adventurous backpackers can obtain permits for backcountry camping amid bison, elk, and prairie dog towns. The combination of exploring both below and above ground in a single park offers a unique adventure experience that challenges visitors both physically and mentally while providing insight into dramatically different ecosystems separated by just a few hundred feet of limestone.
Glacier National Park: Remote Wilderness Trekking
Montana’s Glacier National Park offers some of the most pristine alpine wilderness in the lower 48 states, with over 700 miles of trails crossing spectacular mountain passes and providing access to remote backcountry areas. The Continental Divide Trail runs through the heart of the park, allowing for multi-day backpacking trips where encounters with grizzly bears and mountain goats are common, requiring proper wildlife safety precautions and food storage. High-elevation passes like Swiftcurrent and Piegan offer heart-pounding hiking with exposure and snow fields that often persist into August, while providing breathtaking views of glacier-carved valleys. Technical climbers tackle challenging routes on peaks like Mount Siyeh and Mount Gould, where loose rock and sudden weather changes add to the adventure. Winter transforms the park into a realm of extreme solitude, where experienced adventurers can undertake challenging ski touring expeditions or ice climbing on frozen waterfalls, though avalanche awareness is essential, as the park’s steep terrain creates significant hazards.
Everglades National Park: Wilderness Paddling Adventures
Florida’s Everglades National Park presents a unique adventure landscape where water, rather than land, forms the primary medium of exploration through the largest subtropical wilderness in the United States. The 99-mile Wilderness Waterway offers one of America’s premier paddle adventures, a challenging multi-day canoe or kayak journey through mangrove tunnels, open bays, and river passages that requires careful navigation, camping on elevated chickees (wooden platforms) over the water, and self-sufficiency in a remote environment. Adventurers must be prepared for intense heat, humidity, and insects during the summer months, while winter brings more comfortable temperatures but potentially challenging low water levels that might require dragging boats through shallow mud flats. The park’s saltwater edges provide opportunities for multi-day sea kayaking expeditions around the Ten Thousand Islands region, where paddlers navigate tidal currents and camp on isolated beaches while potentially encountering dolphins, manatees, and a stunning array of birds. Advanced paddlers can attempt the challenging 100-mile Everglades Challenge race from Tampa to Key Largo, which crosses the park and tests participants’ endurance, navigation skills, and ability to handle changing wind and water conditions.
Planning Your National Park Adventure: Essential Considerations
Embarking on adventures in national parks requires thorough preparation that begins with understanding the permit systems, which often involve lottery applications submitted months in advance for popular activities like Half Dome cables in Yosemite or The Narrows in Zion.
