North of Alamosa, off the road that leads toward the Great Sand Dunes, San Luis Lakes State Wildlife Area offers a rare treat: open water and wetlands in the middle of a high desert. That mix makes it a wonderful spot for waterfowl and wildlife watching. It is a wildlife area rather than a state park, so a few simple rules are worth knowing before you go.
First is the access pass. Colorado Parks and Wildlife asks visitors 16 and older to carry a valid hunting or fishing license or a State Wildlife Area pass to enter, so it is good to grab one ahead of time.
Second is the seasonal closure that keeps the birding so good. The part of the area north of the marked buoy and fence line closes from February 15 to July 15 to protect nesting water birds. The rest of the year, when that northern portion is open, you can explore it on foot or horseback.
There are also boating limits worth planning around. Vessels stay south of the buoy line year-round, leaving the northern water calm for wildlife. Camping is welcome in designated areas.
Checking the dates and pass rule ahead of time makes for a smooth visit. For current closure dates, the pass requirement, and boating limits, see the Colorado Parks and Wildlife page for San Luis Lakes State Wildlife Area.
