Miller Trek Trail is a 6.1 Mile loop that starts at Brasstown Valley Resort in Young Harris, GA. It climbs roughly 1,400ft and is a fun rocky and rooty challenge. The signage is a bit old and can be easy to miss, and the trail itself isn't super well worn. However, it's a well known trail in the North GA area and maps can be found on both Strava and AllTrails. The loop is typically attempted counter-clockwise, although the elevation is roughly the same either direction. There is already an existing CR segment on Strava that I am basing this FKT route on.
