Google maps doesn't take you to the correct trailhead. I parked at the upper falls trailhead and walked to the lower trails and back. It's about a 4 mi round trip. Just remember coming back it is a pretty decent climb, so be prepared.
Great out-and-back hike. The falls are beautiful! My Fitbit clocked just under 5 miles, but I don't think it's quite that long; the GPS wasn't connected the whole time, unfortunately.
Great hike, it's a ways here and back, and you get to climb over a giant tree that has fallen across the trail or bushwhack your way around it. As you're getting close you will see North Fork falls first from the trail, then there is a viewing platform for lower Kentucky falls.you may have to scramble over some rocks to get a better or unobstructed view of north fork falls.
2 mile hike downhill on the way in. Well worth the effort to coming back out
FYI you can't get to this via Google maps despite what it says--it takes you to a private road that is blocked with a metal gate. Need to drive to the main Kentucky Falls trailhead
