    "No sidewalks. Not a lot of flat lots. Not many parks outside of old Mill. Streets are windy and not well lit. "
  • Gayle Delaney
    "Like most of my neighbors, I have lived in this sunny and magical home and town for many years (32) and am leaving only to live part-time in Italy and with family in Florida. The extraordinary Redwood forest beauty of our town and our ease of being active neighbors for all sorts of causes and activities is wonderful. Our easy access to hours and hours of local, state and national hiking rail systems is hard to believe since we are so close to San Francisco!"
  • Pat H.
    "Love being able to hike Mt Tam from my doorstep. Love the wine and food festival every June downtown mill valley. Best wines and restaurants showcase their best offerings."
  • Annestuartbricca
    "I have lived in Mill Valley for 3 years and also work for the City of Mill Valley. This is an amazing city to live, work and play in. The trails and open spaces near and on Mt. Tam make some of the most beautiful views in the world accessible by bike or foot. The community is rich in cultural arts and entertainment. I enjoy the quiet refuge of my home in the hills after a day in the bustling downtown area. The parks are pristine and the community center has an indoor pool, brand new gym, dance studio, large/elegant banquet hall and many meeting/classroom spaces that you can rent for affordable prices. While Mill Valley has a reputation for being “stuck up”, “snotty” and “entitled”, I have not experienced this. I do pay an arm and a leg to live here, but in my opinion it is worth every penny and I have never regretted my decision to move here. The Mill Valley City Council is very responsive to citizen ideas, complaints and suggestions, making residents feel as though they have a voice in building the future of MV. With close proximity to San Francisco and Napa, you are in a great spot to travel and get away when you want. I will rent here until I am ready to buy a home somewhere more affordable."
