Red Mountain Trail is real rough. Maintained by local 4WD clubs. Maybe a lifted &/or locked 4WD would be the better choice. This road should be taken by only experienced off-roaders!
Bluer than blue! Western Sierra lake that is not easy to reach, but with a 4WD vehicle, horseback or backpacking in on foot, it is a prime lake destination. Good fishing, decent hiking & great camping. It takes determination to access this special place, so you may as well spend a couple of days here. The first lake you reach will be Red Lake, very nice. But just keep on going another 2 miles up, fore real seclusion. Winter weather can snow as early as October, and by December the dirt road is usually closed for the season.
