(30 ft) The Mosquito Walls are a complicated series of north-facing outcrops and boulders near the parkway. Most are quite low-angle and suitable for short scrambling rather than climbing, but they can be useful for a beginner practice area when the Lower Wall is crowded. A few outcrops offer more varied climbing. Toprope anchors can be difficult to rig and many landings are poor. The walls are situated in a hemlock grove, so they receive little sunlight.
