I took this tour by accident, and loved it. The guide (Art) was so energetic, enthusiastic and outgoing. He was very approachable and encouraged questions. The tour itself was very informative and also with their own experiences being student at this University. It is really a worth experience and I would recommend it. It cost $10 individual and $20 for a family. Bring a camera, it takes around 50 minutes and wear a comfortable shoes. The misspelling (Hahvahd) you need to be there!!!
