The Sevier county highpoint is Fish Lake Hightop. The high point is just north of the popular, and aptly named, Fish Lake. The most commonly hiked route to the summit is via Pelican Canyon, from near the lake. The Pelican Canyon route is about 8.5 miles and 2500' of gain to reach the summit. A much shorter approach is via Hancock Flat, and is the route described here. Using this route shortens the hike to about 7 or 7.5 miles and an easier 1100' of gain. Those with ATV's or jeep skills can drive to less than a mile and a couple of hundred feet of the summit.
Fish Lake Hightop is similar to the Aquarius Plateau to the south. Once on top, it is a gently rolling, remarkably flat plain at 11,000'. The area is stunning in the fall when the leaves begin to change, but a good hike from spring through fall. The road to the trailhead should be accessible by most all vehicles. Even though most of the hike is on a 4x4 road, it is infrequently traveled and still offers a great day out.
