Overview

Diamond Butte Lookout is perched atop a 30-foot masonry tower on Diamond Butte at an altitude of 4,245 feet in the Custer National Forest approximately 40 miles from Ashland, Montana. The lookout was moved from its original location of Yeager Butte in 1958 and was an active fire lookout until 2001. Guests can enjoy panoramic views of the surrounding mountains. This vantage point offers the chance to enjoy sunrises, sunsets and star gazing on clear nights. The lookout is accessible by car, but it is a 200-foot walk up a steep hill to the lookout from the parking area. Guests should be prepared to bring most of their own supplies and gear.
