You will need to make a parking reservation or hike in.
Beautiful large beach, dog friendly, with cute little shops and restaurants in town.
Cute smaller beach, also dog friendly and closer, no amenities other than a English style restaurant on your way in.
Quintessential west Marin small town about a 45min drive northwest, famous for its oysters! You can also rent Kayaks and paddle in the bay which has some great sea life to explore. If you're hungry for something other than oysters stop at the Inverness Park Market and get a deli sandwich, you'll thank us later!
If you like Architecture our Civic Center was designed by Frank Lloyd Wright and is a sight to see! I'm not sure if they do tours on the weekends but even just walking the grounds outside it's lovely. On Sundays from 9am-1pm they hold a giant farmers market that also has prepared food that is quite delicious if you want a two for one outing.
HIKING! There is to many trails to count! Your best bet is to ask Geoff or Fabia for a recommendation, I can't be certain but they might have hiked almost every one out there :)
