A nice hike in the northeast section of Harold Parker State Forest in North Andover will lead you to a small pond fed by a few seasonal streams. You can take several routes to get to GZ including one that was rehabilitated by the Friends of Harold Parker with a new boardwalk and a stone stream crossing between markers NA33 and NA32.
The Friends of Harold Parker is a non-profit organization formed to promote, support, and advocate for Harold Parker State Forest. Since incorporating in 2015, their ambitious volunteers have undertaken several projects, including a successful 100th anniversary celebration, a successful campaign to re-open the Berry Pond swimming area, establishment of the annual Berry Pond Scramble 5.6k trail race, and the publishing of an amazing HPSF map and guide. Volunteers run the popular Wednesday walking group and lead monthly guided nature hikes. Hailing from Andover, North Andover, North Reading, and beyond, on foot, on horseback, and mountain bike, their members represent a diverse range of park users who all want to make Harold Parker the best it can be.
