The swim beach is now OPEN for the season.
Swimming is NOT allowed in the reservoir. Cliff-diving is also strictly prohibited and extremely dangerous. Wading is permitted in the reservoir. A good way to know that you are wading: your feet are always touching the ground!
Swimming is only allowed at the Rock Canyon Swim Beach. The beach is open Memorial Day weekend through Labor Day. The hours are 11 am to 6 pm, Thursdays through Mondays (closed Tuesdays and Wednesdays). There is no extra fee for the beach, but a park pass is required on every vehicle that enters the park.
Please note: Pets are not allowed in the swim beach compound. It is not safe to leave pets in a hot car, so plan to leave your pets at home when visiting the beach. Glass is also not permitted at the beach. Gas grills are not allowed in the beach compound, but bring your charcoal for the grills that are provided.
