This review is for the River Trail, which isn't listed on this site for Roaring River SP.
Blazed in Yellow. We accessed it from near the parking lots by the Fish Hatchery. You'll pass the Amphitheater, or you can pick up part of the trail there, since the Amphitheater kind of interrupts the trail.
This was a short trail but interesting scenery and features. No real climbing, and for most of the trail, you are hugging the River (though not really close enough to get down to it). Narrow along much of the trail, have to go single-file. Some cool rock overhangs and natural "benches." I think kids would like this trail and could manage it well.
