If you’ve never heard of the Appalachian Trail, you probably firstly have no idea how to pronounce it! You wouldn’t be alone! According to websites, if you are from the Northern part of the trail, you say “A-puh-lay-chuhn” and if you are from the Southern part, you say “A-puh-latch-uhn”. What you mustn’t say is “Ap-uh-lay-shun” as you will be ‘perceived as an outsider who doesn’t know what they are talking about’!
Secondly, you may not know where or what it is!
The Appalachian Trail is the longest hiking-only footpath in the world, ranging from Maine to Georgia. It is 2190 miles long, traverses 14 states and has lots of (literal) highs and lows.
For more information, see the trail website or for a comical slant on hiking the trail, see the 2015 movie “A walk in the woods” or read the 1998 book with the same title by Bill Bryson.
