Ranger-Guided Hike to South Twin Lake

Join Park Ranger Patrick Myers for a free guided hike to South Twin Lake, a scenic wetland located in grasslands west of Great Sand Dunes. Hikers will meet at 8:30 a.m. at the Visitor Center, carpool to the trailhead 15 miles to the west, and return to the Visitor Center about noon. Seldom visited by people, South Twin Lake is home to amphibians and shore birds, and is occasionally visited by herds of elk. A small dune above the wetland provides a panoramic view of South Twin Lake, San Luis Lakes, the dunes, and Sangre de Cristo Mountains.

The guided hike is about 2 miles round-trip, mostly across level ground. Hikers will discover and learn about some of the plants, animals, and history of the desert grassland and wetland environments. Bring water, sun protection, insect repellant, and a snack. Although this is not a strenuous hike, participants will need to walk off-trail across desert habitat, and crawl under one fence to access the lake. The round trip hike will likely be completed by 11:30 a.m., and the group will return to the Visitor Center by about noon. Limit of 20 people; call 719-378-6343 or stop by the Visitor Center to sign up for the hike. Hikers coming from Alamosa or other towns to the east may meet the group at the starting location just east of San Luis Lakes State Wildlife Area; ask for directions.

South Twin Lake is within national park boundaries, on land that is privately leased by The Nature Conservancy for bison grazing. The Nature Conservancy partners with the National Park Service in protecting the Great Sand Dunes’ ecological system and its biodiversity.
