The Tokopah Valley Trail is another popular within Sequoia NP for a number of reasons. First, the trail starts next to the largest campground in the park. Second, it's a well groomed trail that has an almost unnoticeable elevation gain. Finally, the scenery is incredible the entire trek with a huge payout at the end - Tokopah Falls. There are numerous places to stop and take pictures, play in the icy stream or hang out by the falls. Even though the trail is likely to be busy, it's well worth the effort to hike to the falls.
Heed the posted warnings and be safe around water!
