Refresh this page for the latest information.

Current Conditions

  • Medano Creek's bed is now most often DRY at the Dunes Parking Lot. Thunderstorms may temporarily bring down a shallow flow of water. There is still 1-2 inches (2-5 cm) of consistent water along the eastern edge of the dunefield, near the Castle Creek Picnic Area. Castle Creek is accessible by high clearance 4WD vehicle on the Medano Pass Primitive Road.

  • As water became low in mid-June, mosquitos emerged in large numbers and are still present. Stay away from vegetation to avoid the worst of them. They are especially concentrated in shady, wet areas in sunny conditions, then spread out in the evenings.
