Recreation opportunities

Approximately 14 miles of the Pacific Crest Trail and the Eagle Creek Trail receive the most use in Mark O Hatfield Wilderness. The Eagle Creek Trail, with seven waterfalls, a tunnel, and designated campsites, can be hiked in a 16-mile-plus loop that includes a climb over Tanner Butte. Eagle Creek Trail's proximity to Portland makes it a popular destination. If you require solitude, take one of the quieter trails; Tanner Butte, Herman Creek, and Nick Eaton Ridge. Each of these is approximately 10 to 12 miles round-trip.
