The shortest, easiest route to Daffodil Flats is 5 miles round-trip, but it’ll feel like 10 miles.
If you want a longer, more challenging, but less crowded Daffodil Flats hike, or if your car isn’t suited for gravel roads, this 6-mile route is a good option.
If you want to try Unnamed, your best bet is to descend from Old NC 105, go to the Daffodil Flats, then go up either Pinchin or MTS and road-walk or hitch a ride back to your car.
If you can’t hike 20+ miles elsewhere in the Carolina mountains, and if you’ve never done a chest-deep river crossing, I wouldn’t recommend attempting this route.
