Oliver Peak is a 8.4 mile lightly trafficked out and back trail located near Victor, ID that features beautiful wild flowers and is rated as moderate. The trail is primarily used for hiking and is accessible from June until September.
Trail start by the Mike Harris Campground and goes to the Oliver Peak. After hiking for about 2.5 miles you get to a intersection where the main trail follows to the right and another side trial goes to the left - take this one to the peak. Then at about 3.8 miles you will have to get off the main trial and hike up to the peak. This section is difficult to follow since the trail is washed out. Note: use the uploaded GPS track to help you get to the top.
Did this with my son (10). It was a pleasant hike. Passed 3 other groups including one motorcycle (trail is closed to motorized vehicles). Once you hit the ridge the trail divides and the main trail drops into the next drainage. Stay left and go southeast on the ridge. The trail continues on past the peak and doesn't go up the peak. We didn't know this and followed the trail to the south ridge then went up the ridge to the peak. Easier route would be to go up the southwest ridge through a sagebrush covered slope (this is how we came down).
