Lorenzo was our tour guide, and he was patient, knowledgeable, and gave us a few nuggets of unknown wisdom. It's July, so it didn't get dark until the end of our tour, but I can imagine that the night tour in September would be so pretty. We are not avid bikers, this tour was great for the whole family. Only maybe 1 slight hill in the 3-hours. We had enough time to stop and see the memorials without feeling rushed. They have it down to a science.
