🥾 Long Trail Directory

8 long trails, with the length each one's own organization publishes and the year that figure is from. Deliberately a short list: a handful we can keep accurate beats a long one we can't, because a wrong length is one somebody builds a plan on. Mileages move — relocations and remeasurement change most of these every year or two — so treat them as a starting point and trust your guidebook over us.

Lengths are the figures each trail's own organization publishes, with the year shown. They change with relocations and remeasurement, so check the source before you plan around one — and whatever you enter for your own hike stays yours, never overwritten from this list.
