Delta Marina RV Resort in Rio Vista sits right on the Sacramento River, giving you that working waterfront feel without the chaos of a bigger marina. The 10 RV sites here have full hook-ups and level concrete pads, so you’re not dealing with any of those uneven setups that can be annoying with a dog on board. Cable TV is included if you want to stay connected on your downtime.

Dogs are absolutely welcome, and the riverside location means you’ve got actual walking space along the water. There’s a fishing pier right there if anyone in your group wants to cast a line, and a restaurant about 200 feet away is convenient for when you don’t feel like cooking. Rio Vista itself is small and walkable from the resort—you can get to shops and other local spots without driving, which is nice for a quick town visit with your dog.

The Sacramento River setting here is genuinely pleasant. You get that sense of being somewhere with actual water activity and commerce rather than a generic RV park in a field. The concrete pads mean you won’t have to worry about muddy conditions after rain, which is a real consideration when you’re traveling with a dog.

To get there from Highway 12, you’ll turn onto Main Street at Rio Vista’s only traffic light and head toward the river. The location is straightforward to find and the resort staff can answer questions about current availability and any specifics about their dog policies before you book.
