Skyline Boulder is a bouldering area in California's San Bernardino National Forest, within the Mountaintop Ranger District. The Forest Service manages the land, and the boulders sit in a cluster with several other climbing areas and trails within a short distance. The climbing here is all bouldering, with nine routes listed and grades ranging from V0- to V2. Among them are Style Hang and Blue Steel, both around V0, and Summit Mining Company at V2. The area's name, Skyline Boulder, points to its location rather than to a single boulder. The closest neighbors are Skyline Slab and Buckthorn Boulder, both about 0.1 mile away, and the Going Green hike at the same distance. For an overnight stay, Buttercup Group Camp is roughly 1.3 miles off, and Big Bear Lake Recreation Area, about 3 miles away, offers fishing.
