Bridger Wilderness, Protected wilderness area in Wind River Range, Wyoming, US.

Bridger Wilderness stretches northwest to southeast across the west flank of the Wind River Range, bounded on the east by the Continental Divide. It covers over 1,700 square kilometres and holds more than 2,300 mountain lakes, seven of the ten largest glaciers in the United States outside Alaska, and Gannett Peak at 4,207 m, Wyoming's highest summit. The Green River rises here and drains the whole area.

The area was first set aside in 1931 as a primitive area, making it one of the earlier federally protected wild lands in the country. The Wilderness Act of 1964 gave it its current official status, and a later expansion in 1984 brought more land under protection.

The name honors Jim Bridger, a fur trader and mountain guide who crossed these passes and peaks in the 1800s as one of the first non-indigenous explorers of the range. Hikers today follow the same high routes he traveled on foot and horseback.

Backcountry camping and fishing both require permits, which are worth arranging before your trip. Motorized vehicles and bicycles are not allowed anywhere in the area, and the high passes are most accessible from mid-summer through early fall.

Seven of the ten largest glaciers in the United States outside Alaska lie within the Bridger Wilderness, along with more than 2,300 mountain lakes. The Green River rises here and, with its tributaries, drains the entire wilderness. Gannett Peak, at 4,207 m the highest mountain in Wyoming, stands on the wilderness boundary.
