Oregon Butte Grand Loop Trail Professional Review and Guide
"The Wenaha-Tucannon Wilderness protects 177,465 acres of forests, canyons, pristine rivers, and basaltic buttes in the remote Blue Mountains of Washington and Oregon. Hundreds of miles of trail traverse this wilderness, yet most see very little use. For you and your dog, solitude, superb wildlife viewing, and a quality backcountry experience are guaranteed.
Although you can traipse through the Wenaha-Tucannon Wilderness from late spring to late fall, it’s best to avoid this area during the heart of summer. It is not unusual for the Blues to record temperatures in excess of 100°F. Surprisingly, they are not dry. Abundant springs can be found along the ridges and slopes, and numerous creeks and rivers drain the canyons. Autumn is the best time to explore, when the air is cool and the larches paint the hillsides golden. However, be advised that hunting is popular here. Know when hunting season begins and be sure that you and your dog are sporting orange."
