The walk back is not simply downhill: regain Bishop Pass from the basin, then descend the long approach to South Lake. The elevation makes a steady pace more useful than chasing a fast time, especially on the rocky upper switchbacks. Snow can linger on the shaded north side into early summer and obscure the tread, so check current conditions before setting out. Day hiking requires no permit, but overnight trips require a wilderness permit year-round; a seasonal quota applies from May through early November. Treat natural water, carry the required bear-resistant food storage, and leave pets behind because they are prohibited on park trails.
