We made our second visit to the Greenbrier River Trail in July 2011 and started at the southern end at North Caldwell. Our first visit was in July 2009 and we started at the northern end at Cass.
The trail used to be a railroad bed and is mostly flat. We rode 18 miles from the southern end (36 miles round trip) and 15 miles (30 miles round trip) when we did the northern end.
