🌊 About Great Sand Dunes National Park — Medano Creek
One of Colorado's most unusual water features — a shallow, sandy-bottomed creek at the base of towering dunes that produces rhythmic, wave-like 'surge flow' pulses from snowmelt, best experienced by wading, skimboarding, or light tubing rather than true swimming.
