When you think of the Blue Hills, you may think of Great Blue Hill, or the ski area, or maybe Houghton’s Pond or the Trailside Museum. However, the Blue Hills Reservation is HUGE, stretching over 7000 acres, from Quincy to Dedham, Milton to Randolph. There are over 125 miles of trails, according to the website. The Blue Hills has much more to offer than just the hike up the main hill (which we love too!).
