Trail Information
Highlights
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!

The trail is in great shape, with some scattered patches of wildflowers. Relaxing drive with great views, and we saw one deer. Always wonder how many critters saw us...

We went up Standard Creek Road to Gravelly Range Drive and headed south to Eureka Basin and into the Red Rock Lakes Wildlife Refuge. We made our way back to Henrys Lake by way of North Valley Road, Elk Lake Road, and Red Rock Pass. The roads were in great shape, and while exploring 80 plus miles of dirt roads today, we only passed two cars.

Eureka Basin in the best trail to access the Gravelly Range if coming in from I-15. We usually take Gravelly Range Drive from North Valley Road because we go in or home through Henry's Lake. Today we decided to take South Valley Road around the Red Rock Lakes and went up Eureka Basin up the Gravellies and down Johnny Ridge Trail. The grass is drying out in the lower elevations. Up high in the mountains, the grass was still green and plenty of wildflowers.
