This is an old inn, one of the oldest in the Gold Rush town of Mariposa that has been recently remodeled. It is a stand-out operation since the owner has begun running the place, and she is very friendly and proud of her place.
The rooms are nicely decorated, the cafe is super great, and we enjoyed being able to walk anywhere in town from our front door. We like bed and breakfasts inns, but if you are on a budget, River Rock Inn is a great combination of charm and affordability.
This is a really small place, less than ten rooms, so expect to deal with the innkeeper, like you would with small inns in Europe. You may have to wait to get a call back regarding reservations, etc. There are no phones in the rooms, and no pool, but we like the price and the peace and quiet found on the back patio under the big trees.
If you get spotty service from the help, tell the owner, she will make it right. The beds are good, and the rooms are clean. We have stayed at River Rock twice in the last two years. It is our favorite place to stay when visiting Yosemite. We don't drive into the park, we just jump on the YARTs bus, it stops close to the inn, and save money on gas and lodging for cheap weekend get-aways.
We are not into staying at chain hotels, so if you are, this may not be the place for you. For us it is a slice of small town heaven. Mariposa is a great little town!
