High Trail
The High Trail starts from Agnew Meadows (shuttle bus stop #1). Instead of crossing Agnew Meadows, the trail climbs partway up the east side of the canyon. There are magnificent views across the valley of the Minarets, Mount Ritter and Banner Peak as the trail contours along the slope to the headwaters of the San Joaquin River. Several trail junctions give options to travel to Summit Lake, Agnew Pass, Clark Lakes, or Badger Lakes. The High Trail is also part of the Pacific Crest Trail. If you continue on the Pacific Crest Trail you will connect with the John Muir Trail near Thousand Island Lake.
This is an active bear area so you must use bear canisters to secure your food and refuse.
Common Destinations: Pacific Crest Trail (northbound), John Muir Trail (northbound), Thousand Island Lake loop.
