Need to Know
The trail begins right near the Livingston Mill and meanders along the creek before turning sharply up the hill. There are a couple short and steep uphills, but these do not last long. You'll cross the creek and then the trail will mellow out. From this point, the trail gradually switchbacks all the way to the pass. There is a nice lake along the way to stop for a snack.
You'll pass smaller and smaller trees as you reach the pass and the views will become ever more scenic. Once at the pass, you'll have a short and fast descent to Frog Lake. This lake is one of the most amazing lakes in the White clouds and has jagged peaks as a backdrop. From this point, the trail descends further and becomes more rocky and challenging.
Starting from an intersection with Livingston Mill-Castle Divide, head downstream, following Little Boulder Creek. The upper reaches of the trail are mostly through the trees over fun and challenging terrain. Although there are plenty of rocks and roots, the trail is very rideable. You'll encounter few big meadows along the way before getting to the lower reaches that hug the hillside side just above Little Boulder Creek.
The route climbs briefly as it moves away from Little Boulder Creek over to the East Fork valley.
The finale of the route is a rowdy descent on dry sage hillsides. As you point your wheel down the last hill into the East Fork of the Salmon River, you'll be treated to downriver views of the Whitecloud Mountains.
