A very unique and amazing trip into the the giant pile of sand that is the central attraction of the Great Sand Dunes National Park. Park HQ is 25 miles north of Blanca, CO or 23 miles east of Mosca, CO, kind of near Alamosa, Colorado. Trailhead is the main parking lot north of the HQ. Basically you climb about a mile up and over the first ridge of sand and camp anywhere. Mind you there is no water in the dunes and the sand becomes intolerably hot during the day (hint: don’t be there when it gets hot!) Elevation is approximately 9,000′ at camp. Round trip distance is only a couple miles and routefinding is straightforward; you just walk out onto the sand.
