Better than sleeping in the car
We stayed here for a night when we arrived at Pismo Beach with no booking, and state campgrounds were full due to COVID-19 diminishing capacity. This campground is squeezed between the railway line to the east and the PCH to the west, in a not very wide strip of land. (Thankfully, the railway line is not very busy, with only 1 train in the evening, and 1 in the morning.) Our site was towards the southern end, and abutted the fence bordering the railway line. There were only 3 or 4 other sites empty in the entire campground (which has over 230 sites). There were mainly RVs throughout the campground, but a smattering of tents too (including ours).
The campsites had the basic fire pit and table, plus a faucet. The toilet block was close, but it was small and not particularly clean. The toilet cubicle doors were bizarrely short in both directions (i.e. the space from the floor to the bottom of the door was way too much for privacy! Not to mention being too short at the top too.) There was no soap dispenser for the hand basins, which I think should be mandatory during a pandemic (and especially considering how much money the campground is making each weekend, let alone at other times). I note that the campground is run by the San Luis Obispo County Parks. Frankly, I think they should upgrade the toilet blocks (at least, the one at southern end; perhaps the others are better but as I didn't use them I can't be sure....)
If we'd have been in our RV, we'd have preferred to save ourselves almost $50 and stayed on a street somewhere. This saved us from sleeping in our car, and made us appreciate other campgrounds we've stayed at all the more.
