Hike two gently rolling miles (one-way) to reach this deep-blue lake at the foot of 11,241-foot Prospectors Mountain. The route winds through conifers and aspen groves before dropping to Phelps’s northern shoreline. Picnic at the sandy beach or take the gasp-inducing plunge into the ice-cold water. Extend your stay: Continue southeast .1 mile to sleep at the designated campsites (permit required).
