This was one of our favorite parts of our New England vacation. We took one of the last tours before the season ended last fall so we didn't see a ton of Moose, but the entire experience was great. One of the Moose we did wee came right up to the bus, it was quite the experience.
The guides were very informative. We did a tour at night in the pitch black, but the bus had plenty of lights on it to shine along side the road. They also had a large spot light that they used. It was hard to get pictures because it was so dark out, but found if I turned the camera to "video" mode that it worked great. If we are ever back in the area booking a tour with Pemi Valley will be the first thing we do.
