Keyhole State Park covers quite an extensive corner of the Keyhole Reservoir, and there are 6-ish separate campgrounds. The main road is paved, but the campground roads are gravel, leading me to deduce that the bigger the loop, the more gravel dust will cover you as the diesel trucks go round and round. So I am at Arch Rock Campground, the first loop and one of the smallest. Also, no boat ramp means fewer trucks.

Another very nice, well maintained campground built around another gorgeous freshwater spring. The one has Alley Mill, a grist mill driven by the outflow of Alley Spring - now a park info center. The mill is a short walk from the campground. If you hunt around for it there is swimming access to the river (swinning in the spring outflow, that's a no no in all these parks).

At the mouth of the John Day River. Mostly families with big boats and big RVs. Like Army Corps campgrounds in general, it's a highly controlled place. I-84 is 1/3 mile away and it is line of sight with nothing but water between it and you, so it's pretty noisy. Quite pretty though, looking right out on the bay ... between the parallel parked big rigs and all their big toys.

A campground on the Natchez Trace Parkway, so you don't even have to exit to get there. Drive past the M Lewis obelisk and up the hill to a really nice, free federal government campground.

How have I not known about this place?! It was nearly perfect in every way for what I like to do on the road. Common Room next to the office with satellite tv. The pool is awesome. Maybe 100' across, 2-4' deep mostly, with incredibly, life-threateningly hot water comong in from the southeast end, and cooling jets shooting out from the south, so you simply ewade in and find your spot!

When Silver Lake Campground is full, this parking area a few miles down the road is open for camping. It's just parking and a few [picnic tables, but it's quite scenic.

I had an initial bad impression because not only do I not get a shower for $24, I don't even get a flush toilet! There is water for RV hookup, but no indoor plumbing, just a clean, unisex outhouse. The lady makes the very good point that everyone is here for the hot springs, and they have showers. On the other hand I am in a nice, grassy, spot a three minute drive (or a long walk) from the Lava Hot Springs pools. So all in all, pretty good. There are some heavily used, long haul train tracks a few hundred yards away that shake the earth a couple of times in the night.

Planning works! This is super sweet BLM campground three miles down the road from Heise Hot Springs. There is a pleasant day use area with river access. The host closes the gate at 10 pm, which is a factor if you have driven back to the hot springs in the evening.

Right on the lake! Spacious, level, wide-open sites. Stupid reservation-only Army Corps sign-up. Bar and Grill 400 yards up the hill.

Overpriced campground, but a very interesting place. The actual Fort is cool, the CCC buildings around it are cool. We are right on the C&O Canal/bike path.

At the Rainbow Road exit off I-80. On the South Yuba River. Super nice place, even if the freeway is 200 yards away. If you're familiar with the Bay Area to Reno run on I-80, there's a place where it crosses some beautiful rapids. This is about ½ mile downstream from that.

Oh, this place is soooo nice! It is now the same management as Miracle Hot Springs, so for your $10 ($8 for senior) you can go to both. Camping over here is both cheaper and way nicer. The Miracle soaking setup is way better (see their Spot entry), so driving to Miracle for your soak and staying here the rest of the time is the best bet. Banbury is a very large concrete pool, with very hot water coming out one place and cold water as many other places as needed. It is next to the river. No wifi.

A quiet little loop of campsites right off US 158. The rest of the park - Visitors Center, access to the Millpond, trails - are a couple of miles to the west then south. Very pleasant place.

Pleasant, well laid out, reasonably priced campground.

Very hot here, tried to choose a site for morning shade. There is a nice trail up the river. Sunset against the mountains across the river is beautiful.

Quite a nice place, despite the $8 "registration fee". Peaceful and quiet and quite close to Bakersfield. Very pleased to be here.

Expensive for the non-resident, but a nice campground in a spectacular location, on the Chesapeake Bay just a few miles north of where it meets the Atlantic. There is a cool little boardwalk access to the beach, where you can walk along the beach to the boat ramp/picnic area/fishing pier a little south. Really fun place.

The TVA is almost like the Army Corps, a gigantic federal agency that builds dams then tosses in a few campgrounds around for fun. This one is below the dam, right across the road from the water. It is fun to watch the barges.

I am in Thumper Loop! A lovely, very well maintained large campground. The area is thick grass, but a wide area is mowed around each campsite. Very pleasant place to be out of the madness of Black Hills traffic.

Way overpriced and has stupid rules. The park borders the Wabash River, but the campground itself is miles from the river. There is a public swimming pool that is an additional charge on top of the camping fee.

The first (lowest altitude) of the string of Inyo campgrounds on CA 168 west of Bishop. The campground itself is very much like Silver Lake CG on the June Lake Loop - exposed sites, not much shade, pleasant and quiet and level with a little stream running along the far edge.
