Lake Anza is a great summer swimming hole in a wind-protected area. Lifeguards are on duty during warmer months.
Lake Anza makes for a great warm weather swimming hole. The parking area is close to the beach along with the trail, which will take you around the lake. The beach gets plenty of sun and is fairly wind protected, which makes for a relaxing day. Bring some picnic food out to the lake and snag your spot early or stop at one of the park's picnic areas and enjoy lunch before or after going for a swim.
Lake Anza also has a cafe in the event that you you're looking to pick up a few things. Keep in mind that dogs aren't allowed at the lake's swimming area. There are lifeguards present for the warmer months and a small fee to enter. Get up-to-date information on Tilden Park's swimming area here.
