This is a moderate out and back trail to Eunice Lake with the option of a climb to Roomie Peak fire lookout.
Be prepared for the 17 miles of dirt road you have to travel to reach this trailhead. You don't need an SUV you just may need to go slower. Be courteous if you are moving slow and pull over if another vehicle behind you is coming up faster.
The trailhead is on the left side of the road a bit before the Mowich Campground parking lot. Park off to the side of the road. You need a national parks pass or America the beautiful for this area.
This is kid friendly. Though the push from Eunice Lake to Tolmie Peak is probably a bit steep for little ones.
