At 9,300', so a short season. A dusty, cramped, low-amenity national park campground that's in a REALLY cool place.
What a cool discovery! You leave Route 160 just a little north of the bridge that takes you to Pittsburg/ Antioch and take a bumpy little road along the edge of Sherman Island. The road follows the southern side of the Sacramento River to the tip of the island, where there is a nice county park for the windsurfers. It's roughly where the Sac River meets the San Joaquin River, and it is a great windsurfing spot.
The most Difficult thing about this place is getting a site! ha,ha. 4.5 winding miles from Aspen make this the budget way for the rest of us to be able to exist for a few days in Aspen.
The third campground after leaving Tioga Pass. It is a few miles and a few thousand feet elevation down, more properly thought of as up from Mono Lake than down from Yosemite. As you're angling down the canyon wall you see a road hundreds of feet down in the valley below. This campground and Big Bend Campground are here. Eventually you get to the turnoff and drive up the road almost two miles and there you are. For some reason the signage is for Bid Bend, but Aspen is the first option you get to. Shady, near the same stream as Ellery Lake, lots of happy trout fishermen, a lovely meadow at the east edge of the campground. Nice enough place, but it ain't no Tioga Lake.
Ten miles of washboard-y gravel road off of Utah 121. Not worth it as it turns out. A very full open-top trash barrel in the middle of the camping area and not even a porta-potty. Some cool big boulders at the edge of the camping area, but otherwise nothing interesting. Update: The signs were (IMO) misleading. I am not at the official camping area. In the morning I chose not to subject the van to 10 more miles of this bumpy, dusty road, so I will probably never know what it's really like. :)
