Midsummer to mid-fall

Day 1
From Cache Trailhead the Bear River-Smiths Fork Trail heads east and, after about 200 yards, crosses the East Fork Blacks Fork Creek. It will be necessary to get your feet wet here, as there is no bridge and no stepping stones crossing the creek. Normally the water is only ankle deep, but if there has been a lot of rain you might want to consider beginning your hike 0.6 miles farther down the road at the East Fork Blacks Fork Trailhead, where the forest service has constructed a bridge. There is a convenient connecting trail joining the east side of the bridge with the Bear River-Smiths Fork Trail. Of course, if you do this the hike will be 0.6 miles longer.

Once it crosses the river the trail almost immediately starts upward, gaining a little over a thousand feet in the next two miles. After reaching the top of the ridge it temporarily levels out and meets the Bald Mountain trail junction. Bear to the right here, as indicated by the sign. Soon the path begins to climb again and within a mile you will be above timberline. Bald Mountain (11,776 ft.) is the large, gently sloping dome in front of you.

At its highest point the trail passes within 0.3 miles of the top of Bald Mountain. If you want to make a detour to the summit it is an easy off-trail walk, with only 250 feet of elevation gain. On the other side of the trail, about 300 yards to the east is Bald Lake. The lake is so close it almost seems as though you could hit it from the trail with a rock, but because it is 450 feet lower it is seldom visited.

From Bald Mountain the trail continues to meander along the top of Bald Mountain Ridge for another 1.3 miles before dropping into the East Fork Smiths Fork drainage. The remaining three miles to Lower Red Castle Lake is a beautiful walk through scattered forest and meadow land, with lots of water and good camping spots. If you got off to a late start you won’t have any problem finding a place to spend the night. This is also a summer grazing area for sheep ranchers, and you will probably see signs of sheep if not the sheep themselves.

Finally, a mile after the trail reaches East Fork Smiths Fork, you will come to Lower Red Castle Lake. There are several good camping spots near the trail on the west side of the lake, and the views of Red Castle Peak are fabulous. After supper you will probably want to spend an hour beside the lake watching the reflections while the last rays of sunset transform the Castle into a glowing ember of red.

Day 2
From Lower Red Castle Lake it is a pleasant 6-mile round trip hike to the two upper Red Castle Lakes. The scenery is excellent, but there are no good camping spots at Red Castle or Upper Red Castle Lake, so leave your camp at the lower lake. The trail continues up the west side of Lower Red Castle Lake, then bends around the west side of the Castle, finally reaching Red Castle Lake on its northern side. Red Castle Lake is 537 feet higher than Lower Red Castle which places it well above timberline. Consequently, there are no trees whatsoever around the higher lake.

From this vantage point you can see that the Red Castle Peak is actually the end of a short spur that extends northward from Wilson Peak on the Uinta Crest. The formation seems oddly out of place, because although the Uinta Crest is composed almost entirely of gray colored Precambrian quartzite the Red Castle is composed primarily of sandstone and shale based material. As a result the castle-shaped peak is not only a different color than the other surrounding peaks, but it has eroded into an entirely different form. Because of the contrast, this rugged peak is probably the most picturesque summit in the entire range.

On the northwestern corner of Red Castle Lake you will find a well cairned trail leading up the talus slope toward Upper Red Castle Lake. The route is not difficult, and the elevation gain to Upper Red Castle is only 247 feet. Upper Red Castle Lake is a small, rocky lake, about 200 yards in diameter. It is fed entirely from the melting snows on the higher slopes of Red Castle Basin and it is not very deep; hence its size varies a great deal from year to year.

The primitive trail from Red Castle Lake does not stop at Upper Red Castle Lake, but continues upward to a small pass on the ridge 628 feet above Upper Red Castle. The extensive Highline Trail is only 0.2 mile south of this low point on the ridge; hence there are many possibilities for extended backpacking trips from Upper Red Castle Lake. Squaw Pass, for instance, is 3.5 miles west along the Highline Trail, and from there it is possible to walk back along the Little East Fork Trail to Cache Trailhead where the hike began. Another possibility: Kings Peak, the highest point in Utah, is only ten miles east along the Highline Trail.

Day 3
The hike back to Cache Trailhead from Lower Red Castle Lake is just the reverse of Day 1. The return is much less tiring, however, since the elevation gain required to get back on Bald Mountain Ridge is only 770 feet, and from there the hike is all downhill.
