My family and I have been to Dos Rios several times. We take our motor home and enjoy a relaxed few days playing in the river, exploring the grounds, cooking, and having a wonderful time with friends. You walk down a small road to get to the river and it is a perfect place for the dogs to swim because they can walk right in. There are kayaks there and that is a beautiful trip!
Last spring the windflowers were amazing. I hope they are again this year. There are a few places to eat in Mason (5-7 min) if you don't want to cookout.
We love this place and will definitely be going back .
