High Dune Trail

While the trail is relatively short, hiking on soft sand makes it significantly more strenuous than typical trails of similar length and elevation gain. It's generally rated as moderate to difficult. The continuous sinking of your feet into the sand and the high altitude (around 8,691 feet) can be challenging, especially for those not acclimated. It's a demanding workout, even for experienced hikers.

The primary characteristic of the High Dune Trail is its soft, deep, sandy terrain. You'll be hiking directly on sand, which can be very tiring as your feet sink with each step. The 'trail' itself is often vague or non-existent due to wind constantly reshaping the dunes. You may also need to cross the seasonal Medano Creek bed, which can have varying water levels.

Spring and fall offer the most pleasant conditions, with cooler temperatures. During spring, the seasonal Medano Creek often flows, adding to the scenery. Summer can be extremely hot, with sand temperatures reaching over 140-150°F, and afternoon thunderstorms are common. If hiking in summer, an early morning or late-night start is highly recommended to avoid extreme heat and potential lightning.

The trail starts from the Dunes Trailhead, which is the main parking area for the dunefield in Great Sand Dunes National Park. This trailhead is easily accessible from the visitor center.

Dogs are generally allowed on the dunefield, including the High Dune Trail, but they must be kept on a leash at all times. Be mindful of sand temperatures, especially in summer, as the hot sand can burn their paws. Always carry plenty of water for your dog.

Yes, Great Sand Dunes National Park and Preserve charges an entrance fee. This fee typically covers entry for a certain number of days. No specific hiking permits are required for the High Dune Trail itself, but you must pay the park entrance fee. Check the official National Park Service website for current fee structures and any specific regulations.

Wear sturdy, closed-toe shoes that you don't mind getting full of sand (many hikers prefer hiking sandals or going barefoot once on the dunes). Layers are advisable due to changing temperatures. Bring plenty of water (more than you think you'll need), sunscreen, a wide-brimmed hat, and sunglasses. Trekking poles can be helpful for stability in the sand. Consider bringing a light jacket even in warmer months for early morning or evening hikes.

This trail offers an 'otherworldly' experience due to its soft, shifting sand terrain and the stark contrast between the vast dunefield and the towering Sangre de Cristo Mountains. From the top of High Dune, you get unparalleled panoramic views of the entire dunefield. You might even experience the unique 'booming' or 'squeaking' sands as you walk.

The High Dune Trail is an out-and-back route. You hike up to the summit of High Dune and then return the same way. There isn't a marked loop option for this specific trail.

In addition to summer heat and thunderstorms, winter hiking is possible but presents different challenges. The dunes can be covered in snow, making navigation and footing difficult. Always check weather conditions before heading out, as temperatures can drop significantly, and winds can be strong. The seasonal Medano Creek may be frozen or dry depending on the season.

To conserve energy, try to walk in the footsteps of others where possible, as the sand may be more compacted. Some hikers find it easier to take smaller, more deliberate steps. Descending can be fun, as you can often 'surf' down the dunes, but be mindful of your footing. Starting early in the morning helps avoid the hottest part of the day and softer sand.
