I did the comprehensive San Francisco tour and the Muir woods tour combo. The tour gives you a very good quick visit to all the major sites in San Fran. I started my trip with this tour so I could figure out where I wanted to spend more time for the rest of the trip. Loved that I didn't have to figure out how to get around on the streets or park! Would recommend this tour to other visitors who would like a one day tour to see most of the main sites. The Muir woods tour was also quick, wish I had more time in the park. But the views were absolutely worth it. Again, loved not having to drive the curving,steep roads with cliffs on one side. If I had to do it again, I would take these tours, but do it on separate days.
