If only going the falls, it's 15 minutes each way. If doing the Daniel Ridge loop, it is 5.1 miles and takes 2 1/2 to 3 hours, depending on your pace. The falls are at the beginning or end, depending on which way you go.
15 minutes if that
To get to the lower (better) falls, it's maybe 30 minutes round trip. The upper falls isn't well marked and maybe 4+ miles out and back.
