First time visitors to this spot. What a peaceful place! The cabin is comfortable, well stocked and nicely maintained. Having running water (non-potable) and a flush toilet is luxury in my book. The kitchen has everything, even a propane stove and gas (we brought and used our own). There was no lock on the gate (just on the cabin). When my partner reached into the pipe at the gate for the lock (we didn't know it wasn't there) he got stung by a wasp nesting in there (be aware). There is an outdoor shower stall behind the garage. We hung a water bag there for a quick rinse. The swimming hole was too cold for us, and the size/water level doesn't really allow for actual swimming.
Regarding the road conditions: on the way in the mapping app took us on the left fork (if driving south on Tedoc road) at these coordinates: 40°16'51.5"N 122°52'51.4"W. Unless you have a 4WD rig with extra clearance, I suggest to not take that left fork. Stick to the right - it's a MUCH better road.
It was so quiet at the Guard Station - over the four days we saw four cars, all parked at trailheads. No one on the roads. The area burnt a few years ago, so it is not as scenic as I assume it once was. We did one nice hike to Black Rock Lake, and visited the abandoned White Rock Guard Station another day. There are not a whole lot of 'attractions' but if you're looking for serenity - this is a great place to find it.
Wildlife sightings included a Pileated Woodpecker, Black-Headed Grosbeaks, Townsend Solitaires, mule deer and a momma bear with two cubs (not at the guard station). Big thank you to the Forest Service for maintaining this sweet spot!
