Absolutely awesome trail! We took Bemis Trail and rejoined the Arethusa Falls trail, but came back down Arethusa and I highly recommend this route. After seeing the two smaller waterfalls on Bemis and heading up, it is a very steep climb, but we successfully completed it with a 4, 8, and 9 year old. It was challenging for someone a tad out of shape, but well worth it. As others have stated, I think coming down Bemis would need to be slow going.
