It was raining the day we did this tour, but our guide did an excellent job covering all the sites. He pointed out the history of the area, he also pointed out the fake tourist sites that had been created in the name of tourism. e.g. Betsy Ross' house is a fake, she did spend some time in Phili but not at the house indicated. The tour ended up in the pub having a beer.
Absolutely brilliant tour, our guide was very knowledgeable and made the tour suit us and the other 2 people that came on it - almost a personalised tour. Finished with a beer and a long chat which was an added bonus.
Great tour very knowledgeable guide, be aware does not enter the buildings but great starting point to plan for return visits to the historic buildings.
