High Dune Loop
Great Sand Dunes National Park, Colorado • October 1, 2024
This route takes you on a completely off-trail dune hike to the top of High Dune and back. Although this route does follow paths that are commonly used to reach the top of High Dune, there are many ways to navigate the dunes. These routes are not marked, and not maintained by the park. The dunes are constantly moving and shifting, so this route itself may change and shift over time. You should be prepared to navigate off-trail. Bring a printed map and compass as backup, and download your offline map ahead of time. You will be walking in deep sand the entire time, and the scenery is spectacular and unique.

Day 0: Arrived at Great Sand Dunes National Park

Highlights
The first day started with a gentle climb through cathedral-like old-growth forest, where massive Douglas firs and western hemlocks created a cool, green canopy. After 3 miles, the trail steepened considerably as we gained the ridge, transitioning from deep forest to subalpine meadows. The wildflower display was spectacular - acres of lupine, paintbrush, and avalanche lilies carpeted the slopes. We took a long lunch break at Panorama Point (mile 5.5) where the full scope of the Alpine Lakes Wilderness spread before us. The final push to Upper Basin involved some rocky switchbacks, but the effort was rewarded with a stunning campsite beside a crystal-clear tarn. We set up camp with plenty of daylight remaining, allowing time to explore the basin and watch marmots emerge from their burrows as the afternoon sun warmed the rocks.
