About the Tam Van

In a quest to educate current park users and inspire new audiences to explore the parks, One Tam created the “Tam Van” mobile visitor center: a retrofitted bread truck that travels to park sites and communities across Marin County. Staff and volunteers dispense maps, trail guides, program information, and friendly advice on how people can make the most of their visit. Since 2015, it has been providing many of the functions of a visitor center, at a fraction of the cost of constructing a permanent facility, and it reaches new audiences that find it difficult to get to the parks due to distance or limited transit options. 

The Tam Van is largely funded by Measure A. Thank you Marin County residents!

Marin Water's Frog Docent Program

For the spring 2022 season, the Tam Van will also serve as the home base for Marin Water’s frog docent program. Frog docents work throughout the spring season to raise awareness about the sensitive breeding habitat for the foothill yellow-legged frog at Carson Falls. If you see our frog docents out at the Tam Van this spring season, stop by and say hi! Learn more about this special frog population here.
