Big Dune Trail

Don't let the short distance fool you — this half-mile-and-change out-and-back packs a surprising punch. You'll leave the trailhead and immediately start climbing loose gypsum sand, which is exactly as forgiving as walking up a beach dune (meaning: not at all). The white sand shifts under every step, turning a modest elevation gain into a genuine leg workout. There's zero shade — you're fully exposed on a blindingly white landscape that feels more like another planet than southern New Mexico. The payoff at the summit is a panoramic view across the dunefield, with wave after wave of white gypsum stretching toward the San Andres Mountains. On clear days, the contrast between white sand and blue sky is almost absurd. This trail is perfect for photographers, curious families who want a quick adventure, and anyone who wants bragging rights for climbing the tallest dune in the park.
