The seemingly boundless Eagle Cap Wilderness contains a complex network of trails that provide many opportunities for exploration. Having traveled many of the trails myself, I never grow bored with hiking in this area. The relatively short trail to Mirror Lake via the Two Pan Trailhead is an excellent hike into the lakes basin area and the ever popular Mirror Lake. The rugged Wallowa granite mountains are a unique backdrop to expansive wilderness landscapes one may not expect to find in Oregon.
The Two Pan Trailhead serves as one of the more popular hubs to this spacious wilderness, and it has quite a large parking area that can accommodate pack animal trailers. Parking is possible along the road below if the parking area is full. Starting at the trailhead, follow the East Lostine River Trail to the south, which skirts the river with one footbridge crossing through the old-growth forest. The shade doesn't last long, however, as you ascend several steep switchbacks before the trees dwindle to reveal an impressive valley. Towering mountains extend over an elongated meadow cut by the East Lostine River with Eagle Cap Mountain off in the distance.
The trail makes a final meandering through another old-growth small forest, ascending a ridge before reaching the Mirror Lake shelf. There is an option to camp at Upper Mirror Lake to the west if the designated campsites at Mirror Lake are occupied. However, for the prime view of the impressive Eagle Cap, obtain one of the many sites along the south Mirror Lakeshore.
