The elevation at the floor of the Mineral King Valley is 7500′ (2286 meters). Hiking at this altitude is strenuous. Gauge your hiking to the least fit member of your party. During the early summer, mosquitoes can be a particular nuisance. As in all areas of the park, it is best to carry water, as the purity of the lakes and streams along the trails cannot be guaranteed. The hikes described below are suitable for day trips, but backcountry permits are also available for many of the areas.
