This four mile segment of the Royal River Water Trail features New Gloucester’s Intervale Preserve. The Intervale provides some of our watershed’s most valuable habitat for migratory birds, waterfowl, and game birds. This section of the water trail begins at the boat launch at the RRCT Intervale Preserve at Intervale Road (Route 231) and ends at the boat launch at RRCT’s Intervale Preserve at Penney Road. Both preserves have good parking, though hand-carry boat access at both ends involves steep muddy banks. This is a good segment for fishing, hunting, and birding in addition to paddling. More Info.
