Open year round with 50/30/20amp sites (seasonal water hook up as well) and tent sites, this small campground is a great place while waiting for a house or on your way out. The bathhouse is super clean, there's dumpsters close by, spaces are decently sized with a picnic table and charcoal grill set up, and trees offer some privacy. There's a playground for the kids, a bike path that can be taken to the shopette or one of the neighborhood playgrounds. Close to the hospital, PX/commissary, and the Muldoon gate.

We stayed two nights at Marathon and it was great. No hook ups at this one, but that was fine. There were bathrooms just a short walk away, a playground across the street, and easy access to walk to the docks, restaurants, the SeaLife Center, etc. Sites were close but not claustrophobic.

Went down on a whim over the Fourth of July weekend, there were a few spots open on the 3rd but it was mostly cleared out by the 4th. Spots are a decent size, we have a Passport Ultralight 2650BH and had enough room to leave the truck parked in front of it and have plenty of space behind us for hanging out. Spots are also well spaced so you don't feel like you're on top of the next site like some places, and there was decent foliage to give a feel of privacy.

Pros: $20/night, there's outhouses and a fresh drinking water pump, good amount of space, short walk to the beach. AT&T had 5G coverage

Cons: Tons of devil's club, not super close to town (but we were ok with that)

My family loved our weekend away at the Russian River Campground. It was super easy to make a reservation online (reserve early!), our loop was a short walk to the boardwalk to get down to the river. However, we ended up with a pull through spot that was a pain to get our rig into (26' pull behind). Luckily it was the first spot in the loop so we were able to back it in and have the door open to the footprint and the slide towards the road (friends in 69, the next spot over) had the same issue. Also, if you have a second vehicle it's going to be horrible to park at the site as well (unless you have two smaller vehicles and are tent camping). But we had a massive wheelchair friendly picnic table, a fire pit with a decent size grate and a bear box.
