The short version
River Rock sits outside Geyserville on Highway 128, and for years it was the only tribal casino within easy reach of Santa Rosa. Graton's arrival in Rohnert Park changed that, and some longtime visitors say the place has slipped. The room is small and dense with slot and keno machines; table games are few and low key. Smoking is confined to a small walled section, and several reviewers mention renovation work tied to a Caesars branded hotel.
Opinion on the slots splits sharply. Some players say they win here often, while longtime cardholders describe tighter machines and free play offers too small to matter. Food gets the same split, with praise for Center Stage and the drink service set against overcooked steaks, slow takeout and a surly cafe counter. Restrooms are limited, and one visitor on a hot day found sinks out of order and soap missing.

Late post. River Rock is a small casino for an older, quieter crowd. There aren't many table games here, but a fair amount of slot machines for a place of this size. I enjoy coming here and having a drink sometimes.
I've eaten at the restaurants here many times and the food is average or below average. Wait times can…
I've been to this casino before this is an update. I'm glad they are renovating this place to add a cesears building attached to the casino. This casino is truly clean and there are lots of slots and keno slots as well. This is a great
I really like this i feel like you actually have a good chance of winning here. Just a little far but worth checking it out and they give you alot of perks so make sure to sighn up for your rewards card.
Food was amazing. Slots were great. We went on a Friday afternoon and had a great time. The staff was super helpful. The casino had alot of slot choices in a smaller place vs other bigger casinos with the same slot choices spread out. My only issue is there is only one bathroom in the whole casino. However I found out there is 2 different ways to get there..
Larissa, thank you for visiting us and for providing us with your feedback. We're especially delighted to hear that you had a great time! Yes, that is correct on our bathroom and access. Also, we do open up our bathroom on the northeast side of our casino on busy nights.

At 3250 CA-128 in Geyserville, about 68 miles from Downtown San Francisco as the crow flies. It's a tribal casino, run by the tribe on its own land.
