As usual, Myrna was a wonderful host and Mare Island is really one of the treasures of the Bay Area. The one thing is that recently the city manager apparently has said you can't use the grills at the sites, which would have been nice to know ahead of time. Also, I am definitely writing a letter to the city manager of Vallejo because I really think this site/place is one of the best things about Vallejo and I think it's worth supporting.
We loved our stay here. Mare Island is a treasure trove of exploring opportunities, just minutes away from the Bay Area. The Tennis Court Yurt was perfect-- cozy beds and lots of room to sit outside and enjoy the oak trees. Myrna was an amazing host-- I had brought along our camping stove & cooking gear but I should have left them at home. Absolutely recommend-- such a wonderful gem of a location.
