There are only 10 campgrounds on Angel Island, so permits are limited! I had the flexibility to go during the week and luckily there were permits available. You have to take a boat to get out to Angel Island so you have to drive up to Tiburon and park your car and get onto one of the Ferry Boats! One of the great things about the island is they have a Immigration museum (think Ellis Island but for the west coast!)

The island itself is about a 5 mile hike from one end to the other with a very modest elevation gain so it's definitely worth doing. Try to get a campsite towards east ridge so you can get a view of Alcatraz and both the Bay and Golden gate bridge. I would definitely suggest this as a tourist many locals tried to show me the best view of the city (Coit Tower, Golden gate bridge and Marin headlands) but in my opinion the best view is to camp out and see the view at night and in the early morning!
