Mount Adams Recreation Area, Recreation area in Yakima County, United States

Mount Adams Recreation Area covers 21,000 acres on the east side of Mount Adams, within the Yakama Indian Reservation. It includes Bird Creek Meadows, known for wildflower displays, and the Great Gap, a three-mile trail-less section of the mountain circuit over two canyons and glacial creeks. The area also contains three campgrounds at Bird Lake, Mirror Lake, and Bench Lake.

The area lies within the Yakama Indian Reservation on the east side of Mount Adams and is managed by the Yakama Nation Tribal Forestry Program. Its trails and campgrounds at Bird Lake, Mirror Lake and Bench Lake are reached from Trout Lake via the Mount Adams Recreation Highway and Forest Road 8225. Bird Creek Meadows closed in 2015 because of the Cougar Complex fire and had not reopened as of summer 2018.

The Yakama Nation manages this land through their Tribal Forestry Program, maintaining traditional connections to the mountain's eastern slopes.

Access is via the Mount Adams Recreation Highway from Trout Lake, then Forest Road 82 and 8225 and Tribal Route 285; all roads after the short highway section are gravel and dirt, often suitable only for trucks or high-clearance vehicles. Campgrounds sit at Bird Lake, Mirror Lake and Bench Lake. Bird Creek Meadows was closed in 2015 after the Cougar Complex fire and had not reopened as of summer 2018.

The Gap is a four-mile trail-less section of the Round the Mountain circuit on the mountain's east side, within the recreation area. Hikers cross two great canyons and difficult glacial creeks, and north of Sunrise Camp at 8,000 feet the route is completely trail-less, including a crossing of the Klickitat Glacier. The circuit rejoins the Highline Trail at Avalanche Valley.
