Santa Rosa does have a great bus system. I have included a link to their website that you may find helpful. If you are looking to live in an area where you are close to major shopping areas, consider downtown Santa Rosa. There are a lot of shops, restaurants and services within walking distance. If you are looking to venture outside of the city limits, the Sonoma County Transit system has buses that travel throughout the county. http://www.sctransit.com/
If you already live in our community, I hope that you find this information useful. If you are planning to move here, welcome! I would encourage you to email or call me if you have any other questions about living in Santa Rosa. I would love to help you.
