Very nice place to stay, although they are a little rigid on the rules. For instance "dog barking is not tolerated, do whatever is necessary to stop the barking." I would definitely stay here again, only I'd make reservation ahead of time!
This is our third stay at Mountain Valley in Tehachapi. It is always clean and peaceful. While there are not sewer hook-ups, there is a dump station. The trees are nice and it is a nice place to walk around.
