Day Hiking

Take the Summit trail for great views of the wilderness and the valley below.  Many horses use this trail.  Day hikers and backpackers should always yield to horses and livestock on the trail. Step off the trail on the downhill side and speak to horses in a quiet voice. This will help them stay calm as they pass you.


Horse Camping

Horse Riding
