It was the journey, not the destination. Dustin (occasionally known as Pablo) was a humorous host. Fully informed, funny delivery, a smooth operator.
Muir woods itself was rather awe inspiring, Sausalito not so much... which is why you don't need any longer there than to grab an ice cream.
Definitely chose this particular tour of the 50 million on offer. The Mercedes sprinter was a cosy way to travel and offered a more personalised experience.
