Camping is only permissible in this zone between December 1 and April 30. From May 1 through November 30, this area is day-use only.
Mostly runnable, the end of this trail is a steep, loose pitch almost unbearable for running.
This trail is best attempted July through September. Snow-packed conditions can exist during the remaining months of the year.
Follow the Pawnee Pass Trail
#907 as it climbs gradually for two miles through wooded terrain and into the Indian Peaks Wilderness. The trail travels from Long Lake
to Lake Isabelle, which sits just below the tree line.
At Lake Isabelle, follow the Isabelle Glacier Trail #908 as it forks left from the Pawnee Pass Trail
. The Isabelle Glacier Trail continues along the north side of Lake Isabelle to Isabelle Glacier, the source of the South Saint Vrain Creek. The Isabelle Glacier Trail ends finally beside Isabelle Glacier in a very steep-walled cirque basin framed by Shoshone, Apache, and Navajo Peaks.
