This was a great trip and wonderfully informed tour guide/bus driver. Muir Forrest was spectacular! Do the drop off in Sausilito and take the ferry across the Bay.
I can really recommend this tour. It was worth its price. We booked it very late in the evening two days before the trip but it was very well organized. We were picked up almost from in front of our hotel it wasn't on their hotel list but they found another, very close, location. The Golden Gate Bay Cruise was very informative and we could see San Francisco, Alcatraz and Golden Gate Bridge from another perspective. We enjoyed it a lot. The Coastal Redwoods amazed us at their size. The given time passed really fast but our driver explained us how the path looks like and nobody was late for the return ride. On the way back we stopped for 10 min. in beautiful Sausalito and could take nice pictures.
I'm giving this tour 4 out of 5 stars because I think we had a little bit too less time in Redwoods 30 min. more would be perfect and the stop in Sausalito was much too short at least 10 min. more would be great.
