Access to the Kaweah River for fishing, swimming and water play can be difficult in the Three Rivers area, because most of the river banks are on private property. In Sequoia National Park the river flows at the bottom of a deep canyon and can also be difficult to reach. The river just above Lake Kaweah is publicly accessible at the Slick Rock Recreation Area; however, this location is inundated most summers when the level of Lake Kaweah is high. Slick Rock, known to locals as "Boulder Beach", has rock climbing areas and historic Native American bedrock mortars. Lake Kaweah itself offers shoreline fishing and flatwater boating. The upper South Fork in Sequoia National Park has good fishing for wild rainbow trout, although a long hike is required to reach it. A California fishing license is required for visitors older than age 16 in the park.
