Really nice biking and hiking experience. It’s not as touristic as some of the other islands (Sausalito) but I do believe it is way better!
We recommend doing the bike across the island and then doing the hike. We rented the bikes once we arrived, but I do believe it is cheaper to do it outside the island and rent them for the day instead.
A must do in San Francisco! You really can’t beat that view 😉
