I wonder how many people are out in the closed Tahoe Nat'l Forest and have no idea it is closed. Many out there (like me) like to get far from other people and do not see anybody for days at a time.
One place I really enjoy is Hidden Lake. It's at (in all pure decimal degrees) N39.40156° W120.62374°. No trails and no signs to it, but it is one of my favorite places on earth. I always have the entire lake to myself (and perhaps a few friendly bears and snakes, etc). Just a hike over the hill from Island Lake, which does have a trail and often has a few people there, especially on weekends, which I try to avoid.
It take a high clearance 4WD to get to the trail head at Carr Lake. Then hike in from there.
Here is a photo of Hidden Lake where I often stay overnight: (not a good swimming lake <leech city>, but handy for all other things):

If I want to take a swim, Island Lake is just over the hill:

Lakes in every direction out there. Finding water is never an issue in that area. Not even during a drought year during late summer.
