Plummer's Ledge Natural Area in Wentworth, New Hampshire is a 3.5-acre (1.4 ha) plot of land protected by the State of New Hampshire to preserve unique geologic features called glacial potholes. Geologists usually account for the isolated potholes, now high and dry, by the plunging of melt water through vertical cracks or crevasses in the glacial ice. These cracks, called moulins, caused water, boulders, cobbles, and gravel to churn with intense cutting power, drilling into the slope of a granite ledge. The three giant potholes at Plummer's Ledge are not only very large and very deep, to 15 feet (4.6 m) across and 20 feet (6.1 m) enclosed depth, but they were cut straight down into a ledge on its 45-degree side slope. The depth is an interesting puzzle. "It is hard to see how either moving or stagnant ice could hold in position a plunging torrent long enough to drill a cylindrical hole ten or more feet deep in rock."The area was deeded to the State of New Hampshire on May 7, 1938 by George F. Plummer and is administered by the Department of Resources and Economic Development under the Division of Forests and Lands. The giant potholes are at the foot of a short cliff approximately 75 feet (23 m) east of Buffalo Road, opposite a lumberyard 2.8 miles (4.5 km) from East Side Road in Wentworth village, 1.7 miles (2.7 km) from Sand Hill Road in Rumney. Access is easiest from a grassy area at the side of the road southeast of the potholes. There are traces of an old trail from the northwest corner of this area, uphill and then turning left towards the potholes, but the trail is obscured by many fallen trees; the area is evidently not maintained by the state. Only one of the potholes has been excavated, and since it is filled with water a visitor cannot see its depth.

The Fly is a short 25-foot (7.6 m) schist sport climbing or highball bouldering route in the Rumney Rocks climbing area, New Hampshire, USA, at the Waimea Cliff. The Fly was bolted by Mark Sprague in 1995 as an open project but did not see a first free ascent until David Graham, an 18-year-old American climber from Maine, climbed it in April 2000, who graded it 5.14d (9a) or V14 (8B+). It was quickly repeated by his climbing partner, Luke Parady. At the time, these ascents were milestones for climbing in North America.

Polar Caves Park is a set of glacially-formed caves located in New Hampshire's White Mountains region, in the United States. The caves were formed during the last ice age from granite boulders and are so named because the deepest cave is cold enough to allow snow to linger long into the summer. The caves are a popular tourist destination. The park contains nine granite boulder caves connected by a series of boardwalks, a giant boulder maze, an animal park with European fallow deer and ducks, and a mining game for children. The caves are lit, well-marked and relatively easy to traverse using walkways and stairs. They are naturally cool during the summer. The caves were first discovered by Bernard A. Campbell, a student at Plymouth High School. Campbell was exploring the area with a group of friends in the summer of 1922 when they came across what appeared to be a small cave, and upon further exploration, they discovered a network of caves hidden beneath the forested area. Campbell recognized the potential of the caves as a tourist attraction and shared his discovery with his science teacher, Henry Minot. Minot was impressed with the caves and contacted Arthur B. Thatcher, a local businessman, to share the discovery with him. Thatcher recognized the potential of the caves and soon purchased the land where the caves were located. Thatcher then began developing the Polar Caves into a tourist attraction, clearing the forest and creating safe pathways for visitors to explore the caves. The first Polar Caves tour was conducted in 1923, and it quickly became a popular destination for tourists visiting the area. Today, the Polar Caves remain a popular tourist attraction in New Hampshire, attracting visitors from all over the world who come to explore the unique geological formations and learn about the history of the area. Polar Caves are located in the town of Rumney, along New Hampshire Route 25, approximately 5 miles (8 km) west of Interstate 93 in Plymouth.

The Sculptured Rocks Natural Area is a 272-acre (110 ha) geology-oriented nature preserve in Groton, New Hampshire. The natural area's main feature is its namesake, the Sculptured Rocks, which are a series of narrow, sharply carved rock formations that are a popular local swimming hole. They are located on the Cockermouth River, which is the longest tributary of Newfound Lake. The Sculptured Rocks Road, which runs along this same river, shares its namesake with the park.

WPNH-FM (100.1 MHz) is a commercial radio station located in Plymouth, New Hampshire. The station identifies itself as "100.1 The Planet" and airs active rock peppered with alternative rock and, more recently, classic rock. The station primarily covers the western Lakes Region and southern White Mountains area, though it can be heard as far south as Manchester and as far west as Barre, Vermont. WPNH-FM originally transmitted from a hilltop in nearby Holderness until the late 1990s when the station's transmitter was moved to the top of Tenney Mountain in Plymouth by new owners. In January 2013, soon after another rock station in the area was purchased by new owners who immediately stopped broadcasting the show, WPNH-FM became the Central New Hampshire affiliate for The Free Beer and Hot Wings Show. It replaced the station's previous morning show, the locally produced "Daily Planet" hosted by then-music director Annie Biello and newswoman Amy Bates. On December 29, 2014, shortly after hiring a new music director, the station began incorporating classic rock into its programming while eliminating most of its classic alternative catalog. The station now primarily broadcasts Westwood One's Rock 2.0 music service, peppering in locally selected music on featured shows like Local Outbreak, Out Of The Box and Punch Out.WPNH-FM's sister stations are WFTN and WFTN-FM in Franklin, WSCY in Moultonborough, and WPNH in Plymouth. The station does not stream its signal over the internet.

Groton is a town in Grafton County, New Hampshire, United States. The population was 569 at the 2020 census.

Tenney Mountain is a mountain near Plymouth, New Hampshire. The summit of the mountain, at 2,350 feet (720 m) above sea level, is located in the town of Rumney, approximately .4 miles (0.6 km) west of the top of the Tenney Mountain Ski and Snowboarding Area.

Smarts Mountain is a 3,238-foot-high (987 m) mountain in the town of Lyme in Grafton County, New Hampshire, United States. Smarts is flanked to the north by Mount Cube, at 2,909 feet (887 m), and to the southwest by Holts Ledge, at 2,110 feet (640 m). Although of only moderate elevation, Smarts is separated from the southwestern White Mountains by Oliverian Notch, a fairly low pass traversed by New Hampshire Route 25 southwest of Mount Moosilauke. That gives Smarts a relative height of 2,190 ft (670 m), which makes it one of twelve mountains in New Hampshire with a prominence over 2,000 ft (610 m).The northwest and south sides of the mountain drain by several brooks into the Connecticut River and thence south into Long Island Sound in Connecticut. The northeast side drains east into the South Branch of the Baker River, and thence via the Pemigewasset and Merrimack rivers into the Gulf of Maine in Massachusetts. Smarts Mountain is the southernmost significant mountain in New Hampshire on the Appalachian Trail, a 2,170-mile (3,490 km) National Scenic Trail from Georgia to Maine. Smarts is outside the White Mountain National Forest, but the trail runs through a narrow corridor along the ridges which is administered by the Forest Service. There was a Learjet plane crash on the mountain in 1996, as well as a Piper Apache twin crash in 1971.
