The two times we've done this trip yielded two dramatically different results. One was a chill trip with Noah with a group that enjoyed it thoroughly, the other was during a bug-hatch that gave it the nickname 'Mosquito Mountain' with JR leaping to the rescue driving a van up the access road to limit the misery.
The true charactar of the hike is hopefully closer to the first experience than the second. It's a short hike up a not terribly high mountain with a nice view of the tidal flats south of Bath not far from Popham Beach. You can actually hike down the other side to a nice beach. There are strict limits on what you can do at the beach since it serves as a bird sanctuary so plan accordingly.
It's also easy enough that we might want to consider doing it with younger girls and add some additional activities.
