Perimeter

Perimeter is a short, easy mountain biking route in the Pemigewasset Ranger District of White Mountain National Forest in New Hampshire. It sits about 0.3 miles from the center of the district, and the whole trip is under a mile long. The route is an out-and-back with a flat profile. The high point is about 1,628 feet, and the low point is about 1,616 feet, so the total climb and descent are each about 29 feet. The steepest stretch is about 0.27 miles in, with a grade of about 2 percent. Summer is the most comfortable time to ride. Typical averages from the nearby Pinkham Notch weather station run to highs around 75°F in July and 74°F in August, with lows in the low 50s. That station sits about 400 feet lower than the route, so temperatures on the trail run a little cooler. Bridle Path, a cross-country ski route, is about 0.1 miles away, and the B&M mountain biking route is about 0.3 miles away. Omni Mount Washington Resort, Bretton Woods, offers lake fishing about 1.4 miles off, and Mount Oscar, a climbing area, is about 2.8 miles away.
