While working in Sonoma, I decided to bike the valley of the moon loops recommended by SRCC. It was very hot that afternoon so I had a slow climb, but once I found my rhythm it was a lot of fun. The only downside is that sometime the roads had several cracks making for a very bouncy ride. My next bike with have some built in shock absorbers! However, I highly recommend this ride for the vineyard views and the charming starting point in Glen Ellen!
