Outdoors and wildfire - San Luis Valley
San Luis Lakes is a State Wildlife Area, not a state park
San Luis Lakes, on the valley floor in neighboring Alamosa County, is now a Colorado Parks and Wildlife State Wildlife Area, where most visitors age 16 and older need a hunting or fishing license or an SWA pass to enter.

On the floor of the San Luis Valley, between Mosca and the Great Sand Dunes, sits San Luis Lakes. The property itself is in neighboring Alamosa County, but it is one of the best-known waters in the valley and an easy drive for many Saguache County residents. Many people still think of it as a state park, but it is managed by Colorado Parks and Wildlife (CPW) as a State Wildlife Area, or SWA. That difference matters for how you visit.
State Wildlife Areas are bought and run mainly to protect wildlife and to support hunting and fishing. Because of that, most people age 16 and older need a valid Colorado hunting or fishing license, or a separate SWA pass, just to set foot on the property. A regular state-parks pass does not cover it. The property also has its own rules on boating, bicycles, and seasonal access, so read the current regulations rather than relying on memory.
The lakes and surrounding wetlands draw waterfowl and shorebirds, which makes the area a good place for quiet wildlife watching. Conditions and water levels change with the seasons and with drought.
Rules at State Wildlife Areas have tightened in recent years, so do not assume old habits still apply. Check the current pass requirements, directions, and any seasonal closures on the Colorado Parks and Wildlife page for San Luis Lakes SWA before you go.
