High Dune on First Ridge
The classic first-ridge climb across Medano Creek to a broad viewpoint over the entire dunefield.
Route overview
Cross roughly 0.5 mi / 1 km of creek bed, climb the visible ridges to the high point and return by the same general corridor.
This is the park’s most common dune objective, but there is no constructed trail. Hikers cross the Medano Creek bed and choose a zigzag line along shifting ridges. Loose sand, altitude and heat make the short distance much harder than ordinary trail mileage.
