This field is part of Tamalpais High School in Mill Valley. There is public access for day use as long as you do not disrupt school activities. The condition of the field’s facilities and ease of use are great. The football field has field turf and the track is a spongy, synthetic surface(as opposed to dirt) that’s kind to the joints and bones! You can use the track and field individually or set up use for team activities. The entrance on Almonte Blvd has a posted sign that details rules for use and whom to contact for group functions. Only downside is that if you need a restroom you’re going to need to find one somewhere else(or brave a port-a-potty by the locker rooms).
