Marion Mountain

The trip was great! This was our first time visiting Marion Camp ground. We went hoping to grab a first come first serve (FF) site. We lucked out and got a site which we really enjoyed (site 19). It was clean and ready to site camp, Parking was nice, easy load in but far from camping on top of your car. Only comment I have was paying for the space and understanding the reservation system took a little figuring out otherwise it was a perfect weekend and already have reservations for Fern Valley in Sept.

Great campsite. Try to reserve one of the sites on the northern edge they are very secluded and have great views.

Good space between camp sites, with a few that are close together as a good choice for groups (such as the inside-the-loop sites). The larger bathroom was cleaner and more odor free than the smaller one in our loop, but as someone who has remote camped, vault toilet camped, etc, the upper was acceptable - it's all about expectations. I'm told that campground opened later in the season than usual due to COVID so bathrooms are in better shape now than they normally would be by this time in the season. Several sites are first-come, first-served. Marion Mountain trail runs past this campground, but it is a severe slope, since the campground is on the side of a mountain, there aren't really any easy/moderate trails right out of the campground. We were fortunate and had water on all week, but there are many warnings that it may not be available. Water spigots are interior so you can't really avoid walking by/through people who are camping when the interior sites are full. We were there mid-week and we did not experience any partiers, just families, hikers, and rock climbers. I would not recommend camping here with a trailer, at least not on the upper loop. We watched one truck+small trailer (17 foot?) bend a rim + blow a tire hitting a rock on a tight corner, and then another travel trailer + camping trailer spend an hour jockeying around, in/out & circling around the lower loop, trying to get into their space. If you're bringing a trailer, my advice is stick to the lower loop. Bring your mosquito repellant.

good..

Pleasantly surprised at finding this gem of a campground. Two small loops of sites. Access to Marion Mountain trailhead to San Jacinto peak is within the campground. While had trouble ascertaining the availability of water a nearby Fern Basin - turned out there was water available at that adjacent campground - so could fill up with minimum inconvenience. Roadway and pad were in excellent condition. Campground clean. Would visit again.

The toilets were completely neglected. We arrived early afternoon on a Friday and never saw the restrooms cleaned or replenished. They stunk so badly from the very beginning. I overheard anther camper say she'd rather go out in the woods to go to the bathroom than use the toilets at this campground, and I agree. One toilet wasn't available (padlocked), which was inconvenient since our loop was basically full.
Our site was fine but very steep climb from the parking spot to the table, and the table wasn't on even ground.
There are only a few sites I would be interested in here, but only if the bathrooms were better taken care of.

Nice camp site. The sites are not very close and access to great hiking. The bathrooms don't have running water. Glorified port-a-potties. Not nice. Otherwise we had a great stay.

Marion Mountain has beautiful views and great access to hiking! It’s one of my favorite camping spots.

We love this place and go back every year. The bathrooms need an upgrade, but that’s all.
