Amazing!!!! My first backpacking trip! We were a group of 10 which included experienced hikers that have done this trail many times and newbies like me. We started in the afternoon on Saturday, camped, hiked to the falls Sunday, camped, then hiked out Sunday morning.
We started at the Jack's River Western Trailhead as marked on this map and made our way to Beech Bottom and the falls, but took the Beech Bottom Falls trail back out to a second car we had parked there so that it wasn't a true out and back trail as marked on here. A car was put there in case we had to bail out because of the storm forecasts. We just had a lot of rain (and quite a bit during the trip at night) so the river level was pretty high. Most crossings were very manageable but nearer to the falls, and if you were to continue east past Beech Bottom along the trail (which was our original plan) the river was past waist deep (I'm 5'5'') and moving quickly. We changed our plans and camped a bit past the falls then double backed the next day to take the Beech Bottom trail out once we experienced how deep the river crossings were becoming. I definitely recommend bringing hiking poles to stabilize yourself while crossing. We heard from other groups that came the opposite direction that some crossings were so deep they had to swim across with their packs.
The falls themselves were amazing and we did the cliff jump after watching a group demonstrate that they were safe!!
The trail wasn't as maintained as other State Parks and National Parks that I've been to -- lots of downed trees to climb over and some overgrown plants but I think that really added to the wilderness feel and it didn't slow us down. We saw one copperhead sunning itself at a campsite but that was the only wildlife encounter. Lots of beautiful scenery, mushrooms, and the river itself made for a wonderful trip.
