All great options. One correction, from trailhead to falls and back, the Abrams Falls route is a 5 mile round trip. There is enough separation between trail and stream in the middle (at the big horseshoe) that hikers and fishers will definitely lose track of one another. If you're looking to do this together, might want to stick with Little River and Lynn Camp options.
