Can we drive back to our location from Møn after the tour?
It gets dark around two hours after sunset, and usually we would finish two hours later. So depending on the time of year and how far away you stay, it could be very late to go back afterwards, especially in summer.
There are many other things to see and do on Møn, so I advise you come early, make a trip around to some nice places, and after the night tour you stay somewhere.
