Recreation areas with activity Backpacking:
To access Observation Trail #132 from the south, follow Trail #192 for 1 mile to the junction with Trail #132. From there, Observation Trail enters the Trapper Creek Wilderness and climbs steadily along the ridge through a second-growth Douglas-fir forest, gaining 2,600 feet in 5 miles as it nears Observation Peak summit. During this 5 mile section, the trail passes the junctions of Trail #195 (at 3 miles) and Trail #198 (at 4 miles). The trail leaves the wilderness and then passes Trails #132A and #192 (at 6 miles) and Trail #158 shortly thereafter. Observation Trail ends on Road 58. Features: Wildflowers, bear grass, and huckleberries. The rugged viewpoint at the northern end offers a majestic view of Mt. Adams, Mt. Rainier, and Mount St. Helens (behind the trees) on clear days.
