I took this tour as while in port on a cruise. We 3 people caught a taxi 10.00 total from the port to the trolley starting point.
This trolley tour was the perfect way to see Boston and hear narratives about its history. I did the hop on hop off therefore I ended up with two different drivers with different narrative styles. Both drivers were very informative and pointed out different historical information on the same route. I really enjoyed the ride on the trolley.
The bus takes you to all the high points of boston. We took the entire route they jumped on the boston harbor cruise. We then came back bussed to a central location location and walked to paul revere's house and the old north church. There is a lot to see and its easy to follow the freedom trail. The tour guide/drivers were very knowledgable about the city. It takes about an hour to make the loop. The harbor cruise is nice, you can get off in the navy yard and catch another boat back.
