Head north then west on Trail 21WO3. In the 2.1 miles, the trail caps off on Mount Pinos (8,810 ft.) where northerly views unfold to the San Emigdo Mountains. From here, hike 3.4 miles to Waypoint 3 then leave the main trail for a 0.2-mile scramble northwest to Sawmill Mountain (8,816 ft.). Pick up the trail again by swinging southwest 0.3 miles. Head to Waypoint 6 and swing off-trail again (heading west then south to avoid big steeps) to Grouse Mountain (8,572 ft.). The payoff includes views dropping 3,000 feet to San Emigoio Mesa.From the top of Grouse, descend northwest 0.6 miles back to Trail 21WO3 then continue west to Cerro Noroeste Road. Walk the shoulder for a half-mile to knock off the fourth peak of the day, Cerro Noroeste (8,286 ft.). After resting, backtrack 6.6 miles to the trailhead, skipping the off-trail detours to Grouse and Sawmill Mountains.--Mapped by Travis Lind
