Sardine Lake is at the base of the Sierra Buttes which are very scenic.
The Sardine Campground is at the east end of the lower lake. One great characteristic of this campground is the interpretive walkway through the marsh.
The signs talk about the beavers who swamped the place, killed all the trees, and now they are gone this is what is left. (I think this is why all the California frogs are dead too.)
The road to the upper lake is four wheel drive only.
It was listed as an intermediate bike ride so we took the bikes up there. However my wife found the rocks very difficult and has no more faith in her book about bike rides. She did ride some of it.
It is only a short distance and well worth the trip.
The off road possibility was to a Tamarack Lake. They say no camping except in campgrounds, but there was one guy up there and it looked great.
We were able to boat around in the lower lake
The Sportsmobile gave me a little grief. I remember reading a post about a guy's bolt in the joint of the two supports of the penthouse backing out. I just scanned it and didn't remember how he got it fixed, but now I faced the problem. The damn thing is under intense pressure with the garage springs working on them. I ended up parking on a slant with the penthouse partially up. This was what it took to get the hole to line up so there was a chance of getting it back through. Then I had to beat it with a hammer.
I know why the nut comes off. They use a nyloc nut which is right for something that is an axle, but the bolt is too short and the nylon part never gets in contact with the bolt so it is easy to wiggle off. WTF. Two thin jam nuts jammed together works. No way of getting the bolt out and replacing it with a longer one.
We checked out the lakes to the north on Gold Lake Road. Snag Lake had a campground on the lake. The big lake is Gold Lake. Allstays didn't show the campground at Gold Lake boat ramp but there is one there. It looks good and is the trail head for a bunch of 4X4 roads. It said National Fee area, not National Forest. I don't know what a fee area is or how to find them on the interweb.
