by CONCORD, N.H. — New Hampshire’s rugged terrain is a paradise for geology lovers, hikers, and anyone seeking awe-inspiring natural landmarks. From massive glacial boulders to dramatic granite cliffs, the Granite State offers a collection of rock formations that reward every challenging mile of hiking and rough driving. Whether shaped by glaciers, rivers, or centuries of erosion, these natural wonders showcase the raw beauty and geological diversity of the region.
According to River City Omaha, these ten rock formations stand out as some of the most impressive and must-see destinations in the state.
1. Glen Boulder
Perched precariously on Slide Peak in the White Mountains, Glen Boulder is a massive glacial erratic that seems almost impossibly balanced on the mountain’s slope. The hike to reach it is demanding, with steep ascents and exposed ridges, but the reward is sweeping views of the Presidential Range and surrounding valleys. This striking formation also serves as a testament to the immense power of glaciers that once dominated the region.
2. The Watcher (Old Woman of the Notch)
Located on Eagle Cliff in Franconia Notch, The Watcher — also known as the Old Woman of the Notch — is a striking rock profile that has often been compared to the state’s iconic Old Man of the Mountain, which collapsed in 2003. While not as famous, The Watcher offers an equally dramatic and somewhat mysterious visage, making it a favorite among photographers and hikers exploring Franconia Notch.
3. Cathedral Ledge
Rising 700 feet above the Mount Washington Valley, Cathedral Ledge is a sheer granite cliff beloved by climbers, hikers, and sightseers. A road and hiking trails lead to the top, where panoramic views stretch across North Conway and the surrounding mountains. Its vertical walls also make it one of New Hampshire’s premier rock-climbing destinations.
4. Madison Boulder
This colossal boulder, located in Madison, is one of the largest glacial erratics in North America. Measuring 83 feet in length, 23 feet in height, and weighing over 5,000 tons, the Madison Boulder is designated as a National Natural Landmark. Scientists believe it was transported to its current location by glacial ice thousands of years ago, offering a tangible connection to the region’s ice age past.
5. Sculptured Rocks Natural Area
Carved by the Cockermouth River, the Sculptured Rocks Natural Area features narrow gorges and smooth rock formations shaped over millennia by rushing water. The area’s swirling potholes and sculpted channels create an otherworldly landscape perfect for exploration, photography, and appreciating nature’s artistry.
6. Flume Gorge
Located in Franconia Notch State Park, Flume Gorge is a natural granite passageway extending 800 feet with walls that rise up to 90 feet high. Formed during the Ice Age, the gorge is a breathtaking destination with wooden boardwalks that allow visitors to walk through its dramatic, moss-covered cliffs alongside cascading Flume Brook.
7. Pawtuckaway Boulders
Within Pawtuckaway State Park lies a wonderland of massive boulders scattered by glacial activity. Known as the Pawtuckaway Boulders, this area is a top spot for bouldering, hiking, and nature walks. The scattered rocks create an adventurous playground for climbers and a fascinating destination for geology enthusiasts.

8. The Basin
Another gem in Franconia Notch, The Basin is a naturally formed granite pothole that spans 20 feet in diameter. Created by the swirling waters of the Pemigewasset River over thousands of years, The Basin is often called the “Old Man’s Footprint” and is easily accessible for visitors of all ages.
9. White Horse Ledge
Adjacent to Cathedral Ledge, White Horse Ledge is a broad granite slope that offers equally spectacular views and climbing opportunities. The ledge’s name comes from the light-colored rock that, from a distance, resembles the shape of a horse.
10. Mount Monadnock Summit Ledges
Famous as one of the most climbed mountains in the world, Mount Monadnock’s summit features expansive granite ledges with unobstructed 360-degree views. The mountain’s exposed rock face is a result of both glacial erosion and centuries of fire clearing the summit of vegetation.
Why These Formations Are Worth the Journey
Exploring these formations is not just about sightseeing — it’s about experiencing the state’s geological history firsthand. Many of these landmarks are tied to glacial movements, volcanic activity, and centuries of erosion, offering insight into the natural forces that shaped New Hampshire.
From strenuous hikes to short scenic walks, these sites offer something for every type of adventurer, making them perfect additions to any Granite State itinerary.
