"This vast, otherworldly protected area contains the world’s largest gypsum dune field—275 square miles of glittering white sand that crunches underfoot and shifts with the wind. It draws photographers, solitude seekers, and adventurers for activities like sand sledding (waxed plastic saucer sleds are sold at the park trading post), the 16-mile scenic Dunes Drive, and ranger-led programs including full-moon evening events and moonlight hikes. Popular trails range from the strenuous, dune-climbing Alkali Flat Trail to the one-mile Dune Life Nature Trail that highlights the unique desert-gypsum ecosystem; a two-mile Backcountry Camping loop offers expansive sunset views. Spring and fall are best for mild temperatures (fall tends to be quieter), summers can exceed 110°F, and winters are pleasantly cool with occasional snow. Practical notes: the single visitor center is the main hub for information and limited grab-and-go provisions, there is a $25 per-vehicle entrance fee, cell and Wi-Fi coverage is limited so download passes in advance, weather or high winds can prompt closures, and visitors are asked to follow Leave No Trace principles." - Evie Carrick Evie Carrick Evie Carrick is a writer and editor who’s lived in five countries and visited well over 50.
