Crater Lake in August: what the park service says
August is one of the three most popular months at Crater Lake, when roads, trails and facilities are usually fully open. The park service says the fall colour and light can appear from mid-August. The Cleetwood Cove Trail to the lake shore is closed for construction until 2029, so until then plan on views from the rim and the 30 pullouts the park lists along the 33-mile Rim Drive.
