Vallecito Reservoir Campground and lake are a very popular fishing lake, with anglers casting for German brown trout, cutthroat trout, rainbow trout, kokanee salmon and northern pike. Boating, water skiing and canoeing are popular activities. A sheltered area for boats and an open play area are just south of the campground. A variety of hiking and horseback riding trails are found in the area. The North Canyon Trail climbs through ponderosa pine and aspen forests. A short side trail leads to a scenic overlook of the lake. East Creek Trail provides access to a lightly used, scenic drainage where fly-fisherman can be seen casting for brook trout.
The campground offers 80 single-family sites, a few of which have electric hookups. Sites are equipped with a picnic table and campfire ring. Vault toilets and drinking water are provided. Day-use picnic sites are located along the creek at the campground entrance and are available for a fee.
