At Your Service Taxi and Tours does a wonderful job providing tours of Acadia National Park and the entire island. The best part was we could stop where and when we wanted and could take lots photos. The driver made us feel like family and we learned so much... lots of interesting facts. You can ask questions easily and not shout over a busload of people. They will pick you up wherever you are to start the tour. We had four in our group and the price was about the same as a bus tour. www.atyourservicetours.com Oh and they are really smoke-free, unlike the other taxi companies, the vans are immaculate. We had to get out of another company who claimed smoke-free because of the smell.
