We very much enjoyed our two hour tour of Acadia National Park on Oli's Trolley. Our guide was very knowledgeable of the area and very interesting. Never a dull moment. She was a very good speaker with lots of interesting facts and walked with us to point out interesting areas and facts we would not know otherwise. This is a worthwhile tour that will not break your wallet. As previous reviewers say it gives you a good foothold if you wish to return to the park on your own. We highly recommend this tour, and yes, you have plenty of time for fabulous photos.
