Here. One of the great things about visiting here is there is no cost for parking!
San Bernardino National Forest are spectacular. At this point you can follow the trail back to the right and intersect with the main trail which will take you back to the parking area. Or you can add on additional length and visit the Duck Ponds (.6 miles) and do the California Tree Trail (.1 miles) which we would highly recommend. Our hike included the loop, a visit to the Duck Ponds, and the California Tree Trail which was just under 2 miles roundtrip and roughly 260 feet of elevation gain.
One of the neat things about this hike is the California Tree Trail which is indicated in green on the Google Map below. This short trail allows you to walk beneath towering giant sequoia trees. Additionally, the hike to the two ponds is definitely worth the visit due to the scenery and the chance to see some pretty large catfish that inhabit the waters.
Rating: Elevation Gain: 260 ft. (Easy), Distance: 2 Miles Roundtrip (Easy).
Time to Complete Hike: 3 - 4.5 hours.
