Recreation

There are many recreational activities allowed on, in, and around Lake Perris and in the State Recreation Park. Guided hikes are offered on the trail around the lake, and several camping sites are located near the lake side. The lake is open for boating from 6:00 am to 6:30 pm from Thursday to Monday. Other activities include

A nine mile paved road loops around the lake which is used to access the different areas of the lake (although the portion that runs along the top of the Perris Dam is unavailable for vehicles) and is also used by hikers, runners, and cyclists. The northwest side of the lake has beaches and swimming areas, picnic grounds with tables and grills, camp grounds including RV camp grounds, a launch ramp, a marina, a small pier, and various peninsulas. The southwest side is the Perris Dam, and allows for rock fishing. The southeast side has picnic grounds, camp grounds, and a rock climbing area. The northeast side is largely left undeveloped in order to preserve the natural flora and fauna, although it is accessible to the public. Furthermore, the paved road strays away from the lake shore thus discouraging people to disturb this section of the lake. Fishing is allowed almost anywhere. Lake Perris has one
