Things to Do

Sand Dunes:

• Sandboarding/Sledding: Rent a sandboard or sand sled from a local outfitter. Climb the dunes and enjoy the ride down! Avoid walking on the dunes barefoot during the hottest part of the day.
• Hiking: Explore the dunes on foot. There are no designated trails on the main dune field, so choose your own adventure. Popular destinations include High Dune (the first tall dune you see) and Star Dune (the tallest dune in North America).
• Photography: The dunes offer stunning photo opportunities at sunrise, sunset, and under the stars.

Medano Creek:

• Splashing and Playing: Medano Creek is a seasonal creek that flows at the base of the dunes in the spring and early summer. It's a fun place to cool off and build sandcastles.
• "Surge Flow": Experience the unique "surge flow" of Medano Creek, caused by underwater sand formations. You'll feel a wave of water as it passes by.

Hiking Trails:

• Montville Nature Trail (0.5 miles, easy): A paved, accessible trail through a piñon-juniper forest near the Visitor Center.
• Mosca Pass Trail (7 miles roundtrip, moderate): A historic trail that climbs into the Sangre de Cristo Mountains, offering panoramic views.

Important Considerations

• Altitude: The park is located at a high altitude (7,500 feet). Take it easy on your first day and drink plenty of water to avoid altitude sickness.
• Sun Protection: The sun is intense at this altitude. Wear sunscreen, sunglasses, and a hat.
• Heat: Temperatures on the dunes can be extreme, especially in the summer. Avoid strenuous activity during the hottest part of the day and drink plenty of water.
• Sand: Sand can get everywhere! Protect your electronics and cameras.
• Leave No Trace: Pack out everything you pack in. Stay on durable surfaces, and respect wildlife.
• Medano Creek: Be aware of flash flood potential during heavy rains.
• Weather: Mountain weather can change quickly. Be prepared for sudden changes in temperature and precipitation. Check the forecast before you go.
• Pets: Pets are allowed in certain areas of the park, but must be kept on a leash. Do not leave pets unattended in vehicles. The sand can get very hot and burn their paws.
• Accessibility: The Visitor Center and Montville Nature Trail are accessible. The sand dunes themselves are challenging for people with mobility issues.

Safety Tips

• Protect yourself from the sun: Wear sunscreen, sunglasses, and a hat.
• Be aware of the weather: Check the forecast before you go and be prepared for sudden changes in temperature and precipitation.
