Highlight: Eureka Basin
Just north of the Red Rock Lakes National Wildlife Refuge in the Beaverhead Deerlodge National Forest, Eureka Basin Trail is the most commonly used trail to access the Gravelly Range from the south. It begins low in the sage-covered grassy rolling hills and climbs for nearly the entire trail to 8346 feet, providing beautiful views before connecting with Gravelly Range Trail. Once on top of the Gravelly Mountain Range, one travels in the sub-alpine grasslands with wildflowers that present fields of different colors seemingly around each bend. Everyone is sure to enjoy the breathtaking views and clean mountain air, and hopefully some wildlife sightings!
