15 Best Hiking Destinations in the US for Every Skill Level

9. Great Sand Dunes National Park, Colorado - Unique Desert Mountain Combination

Great Sand Dunes National Park offers one of America's most unique hiking experiences, where the tallest sand dunes in North America create a Sahara-like environment nestled against the dramatic backdrop of the snow-capped Sangre de Cristo Mountains. Hiking the dunes themselves provides a challenging workout unlike any traditional trail, with the soft sand creating resistance that intensifies every step while the lack of defined paths allows for creative route-finding and exploration. The High Dune, rising 650 feet above the dunefield floor, represents a popular but strenuous goal that rewards successful climbers with panoramic views of the San Luis Valley and surrounding mountain ranges, though the ascent typically takes twice as long as expected due to the challenging sand conditions. For those preferring traditional trails, the Montville Nature Trail offers an easy 0.5-mile loop through wetlands and grasslands that showcase the park's diverse ecosystems beyond the famous dunes, while the Medano Creek provides seasonal opportunities for hiking along a mountain stream that creates natural water slides during spring snowmelt. The park's unique environment creates extreme temperature variations, with sand surface temperatures reaching 140°F in summer while mountain areas remain cool, making early morning or late afternoon the optimal times for dune hiking while traditional mountain trails provide comfortable alternatives during hot periods.
