How much does entry and reservations cost

I can't recall the price, but you can contact Marin County Parks and Open Space for fees and reservations

It can be free if you have a marin county library card but it cost $5-10 for parking,but reservations I don't now about,but I hope that was helpful

It's free. Unless it's the weekend but must pay for parking. The pool you have to pay for.

Thanks 🙂
