Embark on the Smarts Mountain via Lambert Ridge and Ranger Trail loop for a diverse hiking experience that showcases New Hampshire's natural beauty. The ascent along Lambert Ridge, part of the Appalachian Trail, treats you to scenic quartzite ledges with views of Mt. Cardigan and the Dartmouth Skiway, transitioning into beautiful boreal forest as you climb. The highlight is undoubtedly the Smarts Mountain Fire Lookout Tower, offering spectacular 360-degree panoramic views from its 40-foot perch.
This moderate 7.0-mile (11.2 km) hike involves a significant 2191 feet (668 metres) of elevation gain, typically taking around 4 hours and 15 minutes to complete. The Ranger Trail descent can be quite wet and muddy, particularly after rain, so waterproof footwear is a good idea. Smarts Mountain is a great option if you're seeking a less crowded hiking route compared to the busier White Mountain peaks.
Smarts Mountain is recognized on New Hampshire's "52-with-a-view" list, a testament to its accessible yet rewarding vistas. Along the Ranger Trail, you can also spot historical elements like remnants of old telephone poles and a fire warden's garage, offering a glimpse into the mountain's past as a fire observation post. The summit also features a renovated ranger cabin, providing shelter for Appalachian Trail thru-hikers.
