You can park on the street past Sam's or in the paid parking lot across the street
Paid parking across the street and down a few blocks.
I usually park in the lot across the street.
I usually park on the main avenue in Tiburon, 2-3 stops before getting to the roundabout. It's usually pretty easy to find parking, although perhaps less so on the weekends. There are also a few spaces by the railroad museum when it is closed.
