The Clear Lake Loop Trail is an easy, out-and-back hike of about 3.7 miles in the South Warner Wilderness, part of the Warner Mountain Ranger District of Modoc National Forest in California. The trail rises from a low point of about 5,828 feet to a high of about 6,139 feet, with a total elevation gain of about 328 feet. The route is on natural surface, and horses are allowed. Bikes are not. The trail is open year-round, and the Forest Service manages the land. Summer is the most comfortable time to go. Typical averages from a nearby weather station at Jess Valley, which sits about 740 feet lower than the trail, show July highs around 84°F with only about two wet days, while winter highs stay in the low 40s.
