The short 0.1 mile long trail along the north side of Pond Brook is wide and easy. It follows the Brook, passing numerous cascades over large slabs, over a total drop of 100 feet. The top (east) end of the Pond Brook Falls trail, comes to Trio Ponds Road, meeting up with the Trio Trail across the Road.
The Trio Trail begins by passing openings created by beaver activity, now dry, on the left, offering views of Whitcomb Mountain. Previous wood cuts along the beginning of the trail give views to additional nearby peaks. The majority of the trail travels through hardwood forests, with just gentle to moderate ascents. It passes over Long Mountain Brook 3.5 miles from the trailhead, a quarter mile from its junction with the Percy Peaks trail.
It is an addition one mile to the top of North Percy Peak from the end of the Trio Trail.
The Cohos Trail is a system of pathways and spur trails from southern Crawford Notch in the White Mountain National Forest through the Great North Woods to the Canadian border at far-flung Pittsburg, NH. Within this geography it stretches for 170 miles of wilderness hiking. To learn more about the Cohos Trail, visit their website, purchase the Cohos Trail Guidebook and support the organization.
