but what is "switchback"?
From a dictionary:
Noun: A 180° bend in a road or path, esp. one leading up the side of a mountain
That's all it is - a tight sharp turn on a hillside, where the trail zig-zags up the hillside. This allows for a more ride-able grade, and will resist washing out if built properly.
Use it, use it, use it while you still have it.
alright cool. yeah i know waht ur talking about. i usually call them hairpins lol
i think with pavement they're called hairpins but in any sort of bike or walking/hiking trail they're called switchbacks.
