If I remember correctly it took me about 2 hrs. I'm overweight and way out of shape though. There are a lot of rocks to climb down. I probably couldn't have done it without tracking poles. I would do it again in a heartbeat because the Falls are so beautiful.
If you go in from Dennis Cove the trail is easier to hike but it's about 3 hours, but if you go in from 321 it takes an hour and a half maybe but the trails a lot rougher there's a lot of climbing up and down
It depends on which trailhead you start from
