Red Castle Lakes Trail Professional Review and Guide
"Hikers planning a trip to the scenic Red Castle Lakes on the north slope of the High Uintas generally have two different trails to choose from: the East Fork Smiths Fork Trail or the Bald Mountain Trail. The first route, beginning at China Meadows and following the East Fork Smiths Fork all the way to its source, is the most popular route. The East Fork Smiths Fork Trail is very well maintained and has a total elevation gain (to Lower Red Castle Lake) of only about 1,280 feet. The Bald Mountain Route, on the other hand, is much more strenuous. Both trails are within a quarter mile of the same length. I have chosen here to describe the Bald Mountain route to the Red Castle Lakes, primarily because it is the most scenic of the two.
The additional 900 feet of elevation gain is compensated for by the fine views that can be had from Bald Mountain Ridge. The trail follows the grassy, treeless ridge at an elevation of 11,500 feet for almost two miles before dropping down to the East Fork Smiths Fork drainage, and Red Castle Peak occupies a prominent place on the skyline for almost the entire distance. The most interesting way to see the Red Castle Lakes is to hike in on the Bald Mountain Trail and hike out on the East Fork Smiths Fork Trail to China Meadows. Not many people do this, however, because the two trailheads are 50 miles apart."
