We took the drive from Fairbanks to Talkeetna to experience some things that may not be in the interior, and we are so glad we did! It was myself, my folks and my 13 year old son. We were a bit worried about health situations and could not find much on what would be a concern in regards to taking this tour. So, with our particular situation, my mother who has MS and my father who had a hip replacement early last year, both did absolutely amazing with no issues... Perhaps a little sore the next day, but that just means they had a great time! No one had difficulty stopping or "landing". The guides definitely know what they are doing and provided high levels of safety and knowledge of the tour.
