A lot of the Wallowa-Whitman National Forest is not for mountain bikes because the Eagle Cap Wilderness lies within the forest boundary. But, there still is mountain biking near Joseph Oregon and inside the Wallowa-Whitman National Forest.
Trailheads used are the Salt Creek Summit (south end)--19 miles from Joseph Oregon and part of the Redmont and Wagon Road Trail networks, and the Ferguson Ridge Snow Park (north end)--only 14 miles from Joseph Oregon and part of the Redmont Trail network.
Riding season in the Wallowa Mountains is typically mid-June to end of October (depending on snow), with trail clearing using completed by early July.
Routes range from 7 to 20 or more miles and vary from multi-use trails to single-track, with terrain for beginners, intermediate and advanced riders. Some routes intersect so the beginner can reconnect with the advanced rider on the same ride.
We keep mountain biking-specific maps here at the Bronze Antler Bed & Breakfast for guest use. Guests can store their mountain bikes in our garage (along with their road bikes, kayaks, etc.) for easy access.
When you're planning your Eastern Oregon vacation this year, think about some mountain bike rides in the Wallowa Mountains. Plenty of views of the Wallowas and the Seven Devil Mountains across Hells Canyon in Idaho--and a great bed and breakfast to return to at the end of the day!
