Beautiful spot up in the Uinta National Forest. The only fee is the recreation day pass which costs about $5 for 3 days. That's just to park your car. The trailhead begins about 50 yards to the right of the info kiosk. You hike in about 1.5 miles and the lake is surrounded by camping sites. Many firepits exist around the area and are all within 100-200 yards of the lake. You can hike around the lake which is very scenic. Mountain weather changes quick and we got caught in snow with a sudden drop in temp. Gear worked well and it turned out great.  Make sure you sign the hiking log so rangers know you're out there. Can be found at the Wall Lake trail head. Cross over the little bridge at the lake and hike a little behind the trees to find some amazing camping spots!
