Located in Great Sand Dunes National Park, Medano Creek is one of the most interesting features in the park that experiences a yearly surge flow in the spring. During the spring melting, the creek becomes deep and you can see it flow right across the sand. Spring is the perfect time to see this hydrological event, and you can plan a day to play and cool off in the Medano Creek surge flow.

Quick Overview of Medano Creek Surge Flow
Medano Creek Surge Flow is a unique natural phenomenon where seasonal snowmelt creates a series of impressive, rhythmic waves of water flowing across the sand dunes. During the surge you can actually see the water moving across the sand.
Typically occurring in late spring and early summer, this surge flow is driven by the melting of snow from the Sangre de Cristo Mountains, which feeds into the creek. As the water moves through the dunes, it forms a series of undulating waves that can be enjoyed by visitors as they wade through the shallow, cool waters. We visited in late April and enjoyed getting to see the flow!
You can see more details about this hydrological event at the National Park Service.
How to Visit the Surge Flow at Medano Creek
While you can’t 100% predict that you will see the surge flow in Medanon Creek, your best bet is to visit during the spring months or early summer. The flow is best in the middle of the day into the afternoon.
Wear water-friendly shoes or sandals, as you’ll be wading through shallow, flowing water. The surge flow is accessible from the park’s main entrance, with plenty of parking and a short walk to the creek. Be prepared for varying water conditions and check current flow reports on the park’s website before your visit. While some kids had some floats, the water is not deep enough for swimming. You can easily spend a few hours enjoying the creek.
