Do not use this company!! I can’t stress that enough. My 5 friends and I bought tickets for a tour to Muir Woods 2 months before going to San Fran. We were told to arrive at 9 am to get on the bus (that was supposed to be a Hop on Hop off bus/ Double Decker bus. When we arrived, it was just a regular van) that was supposed to take us over the Golden Gate Bridge, through Sausalito and to Muir Woods. We got there to redeem our vouchers and were told to go get on the bus that was parked across the street. When we got there, we quickly realize that there is definitely not enough room for all of us, plus the 20 other people who were in line ahead of us. And sure enough, there wasn’t. They told us that they could either give us a refund or we could get on another bus that goes around the entire city of SF, drop us off at the Golden Gate Bridge, get on another bus that will take us across the bridge into Sausalito. The bus that was supposed to pick us up in Sausalito was supposed to be there at 12 pm. Well by the time we rode the bus all the way around the city, scrambled around to find the other bus to get on, we still had 2 hours to kill in Sausalito on a Sunday morning, when nothing is open.
Keep in mind, this trip was originally supposed to be over and done with by 12:30 pm at the latest and it was now turning in to a entire day trip. When you plan to spend 4 days in SF, you can't afford to spend 7 extra hours on a trip you only planned to be 4 hours long. So frustrating.
We finally got to Muir Woods and when we got back to Sausalito, we missed the Ferry (which we already paid for) so our only options were to either pay more money to get on a different bus or wait 1.5 hours for the next ferry.
The most annoying part of this whole thing is that they do this every single day! They sell more tickets than there are seats on the bus and then end up making $5 from every person who didn't get a spot on the bus. They knew exactly what to do and didn't skip a beat. I even asked if this was just a fluke mistake or if this happens regularly and she avoided the question.
Luckily my friends and I are young and have good attitudes so we decided to laugh it off after being very frustrated for a while and we made the best of it. But it was not ideal and pretty disappointing. I would suggest you try and find another tour to Muir Woods. Good luck.
