MANY things went wrong with this tour, I will try to summarize. After reading all the good reviews I decided to try this tour. The tour was supposed to start at 9 a.m. and include a city tour, Muir Woods and Sausalito. The day before leaving I got an email saying the tour will now begin at 2:00. Considering that is when the tour was to end, I was upset but it was still OK. I checked in at 1:00 and the clerk said "now just like this morning..." and I stopped him there asking what he meant by this morning when my email said 2:00. Apparently the tour of the city still began at 9:00 but then there was a huge break before going to Muir. The clerk was nice enough to refund me some of the money without hassle so I was still OK but upset that I came into town the night before and paid a crazy amount for a hotel so I could be there at 9:00 but whatever. The clerk informed me at check-in that at 1:45 we would get on the bus and he would come out to assist us in the boarding process. At 2:15, having heard nothing at all from anyone on where our bus was, the clerk finally came out and said the driver hit traffic and would be at least 20 more minutes. Really, traffic in San Fran? Go figure. How he didn't account for this I do not know. The clerk should have been out talking to us at 1:45, not after a half hour of us all waiting and wondering what was going on.We boarded the bus, which was clean and comfortable. After about 5 minutes into the tour by the most monotoned person I have ever heard, he mentions that we are not able to go to Muir Woods because they are only sporadically open due to the government shut down. We all took the tour for Muir Woods yet no one on the bus knew we were not actually going there. The driver assured us we would still see Red Woods but from a different park. The park turned out to be in the middle of a neighborhood and he dropped us there, said he would be back in 1 hr and 15 minutes and left us with nothing to do. We saw nothing but pines in an average, regular neighborhood. We asked the bus driver about the trees and told him how upset we were over the whole situation. He empathized but had no solution and told us what we thought were pine trees were really the red woods, second generation. We got to Sausalito at 5:00, the town closes down at 6:00. Boring town with only a few expensive shops. Overall waste of money and 5 hours. Very boring tour host on top of everything else.

We were only in San Francisco for a day and a half so this was a great way to see a ton of stuff. Our guides were great and extremely knowledgeable. The buses were super comfy and I was very impressed with the skills of the drivers.

Six of our family members on a cruise were booked for this tour. We were supposed to leave at 9:30 and arranged an Uber to pick us up at the pier. Unfortunately, the port had a problem with the gangway, so we weren't allowed off the ship until nearly 10:00 a.m. Since our tour had already left before us, we went to the Gray Line Office in town and explained our dilemma. The person there, although very friendly and apologetic, booked us on a substitute for the morning, a Hop On Hop Off bus so we could find our way to the sights we wanted to see. Our Muir Woods/Sausalito trip was still booked for the afternoon, so we left the office and went to catch a Hop On Hop Off bus. We waited for an hour and although some came by, no one got off, so there were no seats for us. Then we waited nearly another hour, and finally got on a bus, but there were only four available seats up top, so I sat on the bottom, where I could see nothing because of the window covering down below. This bus took us to the Golden Gate, let us off, and then we had to get another bus going back into town. We got to see very little, where the original Super Saver tour we were booked on included a city tour. It was our first time in San Francisco, and we were very disappointed. At the bus stops, we saw about three times as many Hop On Hop Off buses run by other companies, but our tickets were for Gray Line, which were few and far between. We did go to Muir Woods and Sausalito in the late afternoon, and this was a wonderful excursion with the most knowledgeable driver/guide ever ,but the morning was a waste of our time and money. I will never recommend the Gray Line HopOn HopOff to anyone visiting SanFrancisco. I've been trying to contact Viator to inquire about a refund, but have been unable to do it online, so I will be calling them. I do highly recommend Muir Woods and Sausalito.

Both tour guides were awesome ! Truly exceeded our expectations ! Special thank you to Danilo for hosting an amazing SF tour! I forgot our afternoon tour guides name but he was equally awesome ! Will def recommend !

The drivers were both good and friendly. There was plenty of time at each stop to see and do anything we wanted to do. We did this tour our first day so we could decide what to do the rest of the trip. Greg (city tour) recommended several places to eat and they ended up all to be great. Definitely get the clam chowder at the Cliff House! The Sausalito trip was not worth the stop.

It was a good experienced. Our tour guide Randy is very accommodating and entertaining. He got a lot of tips on places to go to eat, what is the best restaurant, etc. The Muir Woods experience is the best. Totally recommending this tour.

Absolutely amazing tour.

The tours were great especially the Muir Woods. Taking both tours on the same day was a bit much and I would split it into two days.

The tour itself was good you get to see a lot of the city and Muir Woods is amazing but I found the organization of the tour to be very poor compared to other tours I have taken throughout the USA and Europe. We were told we would be picked up from our hotel at 8 am - the bus was 20 mins late I understand that it happens sometimes but a call or text would have been nice as we waited outside in the cold for 30 mins and were beginning to think we were going to miss our tour and the bus was completely different colours from what we were told to look for green and white vs blue and grey. You're then dropped off at the main office the tour does not start right away after the hotel pick ups. It was absolute chaos at their main office in the morning where all of the tours depart from with people and buses everywhere and nobody tourists or the people working seemed to know where to go. There was no stop at Golden Gate Park as indicated in the description just a drive through it. Also important to note that it says it is an 8 hour tour but the tour started at 9 am and did not end until 7 pm we had expected to have more time to ourselves in the evening. You return to the main office and switch buses and guides between the city tour and Muir Woods tour which we were not expecting. Both of our guides were very good however our guide for Muir Woods had a strong accent and it was difficult to understand him, particularly as he was speaking through a microphone on a moving bus which was unfortunate as he was a very nice man and very knowledgeable. Overall I'm glad we did the tour as it allowed us to see a lot in one day but I would not book this tour again knowing what I know now.

the day of the tour we discovered it was actually two separate tours so had a break in between. We crossed the Golden Gate Bridge each time and travelled some of the same city streets. Because of that, we spent more time on the bus than we had expected. Each of the guides were knowledgeable and shared interesting stories and information. The tour showed us the varied areas of the city . This was the perfect way to see Muir Woods - no worries about driving the winding roads or parking. We could have skipped the Sausalito stop. It was late in the day and very overcast and cool outside. there wasn't enough time to do more than walk the street.
