Sandboarding the Gran Desierto de Altar Dunes

The towering sand dunes on the edge of the Gran Desierto de Altar, one of the largest active dune fields in North America, offer a sandboarding experience similar in feel to snowboarding, with riders sliding down steep dune faces on a waxed board. No prior boarding or snowboarding experience is necessary, since guides provide a basic technique briefing and most first-timers start by sitting or lying on the board before progressing to a standing stance on gentler slopes. Boards and basic safety gear are typically included with a guided outing; participants should wear closed clothing that covers the skin given the abrasive sand, along with sunglasses or goggles and strong sun protection, since the dune faces offer no shade whatsoever. The activity suits most fitness levels, since the main physical effort is the walk back up the dune after each run rather than the ride itself. Sandboarding is possible year-round, but the desert heat during Sonora's long summer makes climbing repeatedly up soft sand genuinely exhausting and risky; the cooler months from October to April are far more comfortable and are when most operators recommend booking.
