The general route starts from the parking area at Paradise, then heads south to Reflection Lake. From about the mid-point along Reflection Lake’s south shore, cross the closed Stevens Canyon Road, heading south. Here is where the real routefinding begins as there are a few different bowls, ridges and passes ahead. The pass lies to the east of the Castle.
