Have to say this was the best tour we did in San Francisco with Dustin the guide being just about the perfect host. Started with Alcatraz and although this is billed as a must do think long and hard about going. The organisation is great and the rangers knowledgable and super friendly. But this was a high security prison that imposed brutal conditions on its inmates, it isn’t a film set. Came away feeling a bit unclean and disparing at mans inhumanity. The flys are awful as well. After this it just got better and better. Dustin was great, Muir woods is definitely a must see, nature at its most aweinspiring and wonderfully tranquil best. Sausalito was beautiful a touch of the Mediterranean on the west coast. Great views, great company and a great guide.
