About Split Rocks

Split Rocks sits just east of Jumbo Rocks along the park loop road (parking at the end of a cul-de-sac about 1.2 miles past Jumbo when driving east), named for the huge split rock immediately north of the parking area. The area encompasses multiple sub-areas — Split Rocks East, Split Rocks West, Future Games Rock, Isles in the Sky — with a good spread of moderate trad. Short walk from the Split Rocks picnic area.
