Okay, we need to be upfront - Devil's Path is no joke. This is the hardest trail we've ever hiked, and we say that as people who genuinely enjoy a challenge. Twenty-five miles across multiple peaks with about 14,000 feet of elevation gain. Our legs were sore for a week.
We broke it into a multi-day trip with overnight camping, which we'd strongly recommend. Trying to rush this trail is a recipe for misery. The terrain is incredibly rugged - steep climbs, rocky scrambles, and sections where you're basically pulling yourself up by tree roots. It's as much of a mental challenge as a physical one.
That said, the views from the various summits are absolutely spectacular. There are stretches through the Catskill forest that feel completely remote and wild, which is rare this close to the city. Some sections are more wooded with limited views, but the open summit panoramas more than make up for it.
Trail markers can be a bit sparse in places, so definitely bring a good map and know how to use it. We got slightly off-trail once in a rocky section and had to backtrack. This isn't a trail for beginners - please be honest with yourself about your fitness and experience level. But if you're ready for it, Devil's Path is one of the most rewarding things we've ever done.
