I am so embarrassed that I had never heard of the ‘INTERNATIONAL Appalachian Trail’ thought it has been around for over 30-years. What makes it worse is that during that time I have hiked small sections of the AT & living in New Hampshire I am very much in AT country.
Yikes, & to make it worse I heard about it on Facebook — albeit in the ‘Maine Hiking‘ group to which I belong. I had to ask them ‘how & why’ AT became ‘International & as ever they were very polite & helpful.
So, I wanted to make sure YOU knew about it.
So, I made further inquiries. Yes, of course, you need a passport to cross the Canadian border — & YES, the border is still closed because of COVID.
Thought you will find this useful & interesting.
