Rush Creek Lakes (Kinney Camp) Trail is a 13.5 mile lightly trafficked out and back trail located near Lewiston, CA that features a lake and is only recommended for very experienced adventurers. The trail offers a number of activity options and is accessible from June until October. Dogs and horses are also able to use this trail.
The only reason this doesn't rate 5 stars is because of the lack of water the first 7 miles. It starts out moderately through forest & gets more strenuous when you come to a long, exposed (hot!) ridge. It goes back down along a rocky hillside, then into forest & up a brushy hillside before crossing a creek--these last stretches are usually not maintained, so be prepared for a bushwhack or bring shears. Once you cross the creek it's an easy scramble up the granite to the first lake. It's a little harder to get to the second lake & harder yet to the upper lake, but swimming is best at the upper lake. Early season there's streams & ponds everywhere.
