Pawtuckaway State Park features 32 miles of hiking trailswith difficulty ranging from easy to hard. Trails lead to the approximately 900-foot summits of North and South Pawtuckaway mountains and connect the ring dike area to the lake. Most popular routes are loop trails that incorporate ridge walks and mountain summits. Key scenic highlights include a mountaintop fire tower, an extensive marsh where beavers, deer, and great blue herons may be seen, and a geologically unique field where large boulders called glacial erratics were deposited when glacial ice melted near the end of the Ice Age. A short 15-minute hike brings visitors to the fire tower at the top, withgreat views of the area and views to Pawtuckaway Lake. The park’s boulder field is of interest to boulderers, along with roped climbing. The Fundy Trail goes right alongside Burnham’s Marsh, so pack binoculars if you want to do some wildlife viewing. An easygoing route leads visitors to a boulder field, though it’s downhill on the way there, so save some energy for the uphill return leg. The Pawtuckaway Mountains form the outline of an ancient volcanic ring dike dating from 130 to 110 million years ago (Cretaceous).
