Which Should You Visit?
Both destinations deliver surreal dune landscapes that feel extraterrestrial, but they operate on entirely different rhythms. Lenis Maranhenses in Brazil transforms seasonally—visit between June and September to witness thousands of turquoise lagoons nestled between pristine white sand dunes, created by rainwater pooling in valleys. Outside this window, you'll find impressive but empty dunes. White Sands National Park in New Mexico maintains its otherworldly character year-round, offering the world's largest gypsum dunefield where you can sled down cool white slopes even in summer heat. The Brazilian experience centers on swimming in warm lagoons after hiking endless dunes, while New Mexico delivers stark desert beauty with easier access and infrastructure. Your timing flexibility and desired activities—water versus pure desert—will determine which delivers the experience you're seeking.
