Everything OddWay knows about. Narrow it down by what you're after, or where you're going.
Giant objects, odd monuments and things built for no clear reason.
Brookline, NH
More than 100 large-scale sculptures are scattered through roughly 140 acres of wooded hiking trails on Potanipo Hill. The pieces appear unexpectedly among rocks, trees and former ski-area terrain, turning the mountain into an outdoor gallery that feels more like a scavenger hunt than a conventional museum. Trails are open daily from dawn to dusk.
Wilton, NH
A roadside obelisk marks the place where Captain Samuel Greele was killed by a falling tree in 1798. Instead of moving the memorial into a cemetery or town square, later residents preserved the exact location of the freak accident. The monument is visible from the roadside but should be approached only where it is safe to pull off legally.
Moultonborough, NH
The mountaintop mansion known as Lucknow was completed in the early twentieth century for industrialist Thomas Plant. Its Arts and Crafts design incorporated then-cutting-edge technology including unusual plumbing, refrigeration and electrical systems. The estate, trails and mansion are ticketed or seasonally operated depending on the area.
Manchester, NH
An otherwise ordinary pedestrian alley in downtown Manchester has been turned into a gallery of cat-themed murals. More than 20 painted cats appear in styles ranging from realistic portraits to pop-culture riffs. The public walkway is free and open year-round.
Rindge, NH
This outdoor sanctuary spreads memorials, stonework and worship spaces across a hill facing Mount Monadnock. Its centerpiece is a massive open-air altar assembled as a memorial to Americans who died in military service. The grounds are generally open dawn to dusk year-round, although staffed facilities have more limited hours.
Littleton, NH
Chutters' downtown store contains a candy counter stretching 112 feet along the shop, once recognized by Guinness as the world's longest. Rows of jars and bins turn an ordinary candy shop into a deliberately excessive roadside attraction. The business is currently open seven days a week.
Lincoln, NH
Clark's has operated as a White Mountains roadside attraction for generations, combining trained bear shows, the White Mountain Central Railroad and a collection of intentionally old-fashioned amusements. Its mix of live animals, steam trains and roadside-showmanship history makes it a distinctly New Hampshire oddity. The attraction is ticketed and seasonal.
Contoocook, NH
This long wooden bridge was built for railroad traffic rather than wagons or automobiles and survives as one of the country's oldest covered railroad bridges. Its heavy timber trusses once carried trains across the Contoocook River. Today the preserved structure can be explored on foot from public areas.
Concord, NH
A downtown mural transforms a tall elevator shaft into a giant level of the classic Donkey Kong arcade game. Painted in 2022, the work uses the building's vertical shape as part of the joke, with pixel-style platforms climbing toward the roof. It is best viewed from public streets without entering the residential property.
Sargent's Purchase, NH
Inside the Sherman Adams Visitor Center at the summit of Mount Washington, this museum recreates the extreme weather that made the mountain famous. Exhibits cover the observatory, brutal wind, cold and the 231-mph gust measured here in 1934. Reaching the museum requires reaching the summit by hiking, the Auto Road or the Cog Railway, and seasonal mountain access can change rapidly.
Hart's Location, NH
Frankenstein Cliff rises dramatically above Crawford Notch and is reached as part of a steep hiking loop near Arethusa Falls. Despite the horror-movie association the name suggests, the cliff honors nineteenth-century landscape painter Godfrey Frankenstein rather than Mary Shelley's creature. The coordinate routes to the established trailhead rather than to the cliff face itself. Trail source: https://www.trailfinder.info/trails/trail/crawford-notch-state-park-frankenstein-cliff-loop
New Boston, NH
A massive split boulder in the woods resembles a crouching frog when viewed from the right angle. Frog Rock was once a well-known nineteenth-century scenic curiosity before changing roads and travel patterns left it comparatively obscure. The natural formation remains reachable on foot and makes a strong old-school roadside-oddity detour.
Greens, NH
Garnet Pool was once promoted as a scenic Victorian-era swimming hole near Mount Washington before fading from mainstream tourist maps. The secluded pool and surrounding rock formations survive without the formal infrastructure of a modern attraction. There is no clearly signed official trail, conditions can be slippery, and the source warns that common map directions can be wrong, so visitors should use caution and avoid treating it as a guaranteed swimming stop.
North Woodstock, NH
Each winter, crews build a walk-through landscape from hundreds of thousands of icicles and massive frozen walls. Tunnels, towers, slides and illuminated chambers change shape as the weather changes, making the attraction temporary by design. Opening dates depend heavily on winter conditions and tickets can sell out.
Madison, NH
Madison Boulder is an enormous glacial erratic carried and deposited by moving ice during the last Ice Age. The exposed granite block is roughly the size of a small building and has long been promoted as one of the largest known glacial erratics in New England. A short approach makes the scale easy to appreciate from ground level.
Northfield, NH
Industrialist Charles E. Tilton built this massive Roman-style stone arch as a memorial to his ancestors. It stands high above the Winnipesaukee River and looks wildly oversized for the rural hilltop around it. A short trail leads visitors to the monument and surrounding views.
Milford, NH
A narrow iron suspension footbridge crosses the Souhegan River in Milford, swaying noticeably as pedestrians move across it. The current bridge dates to the nineteenth century and feels more like a miniature Victorian suspension bridge than a typical town walkway. It remains a pedestrian crossing, so visitors can experience the movement directly.
Hanover, NH
Mexican muralist José Clemente Orozco covered the walls of Dartmouth's Baker-Berry Library reserve corridor with a dark, violent and often surreal interpretation of the history of the Americas. Gods, skeletons, machinery, conquest and war fill the panels rather than the genteel imagery expected in an Ivy League library. Public viewing follows current library access policies.

Durham, NH
The Paul Bunyan Tree was a famously massive old tree in the University of New Hampshire’s College Woods, estimated to be more than two centuries old rather than something “built.” Current map data identifies the individual tree as deceased, so a traveler should not expect to find the living giant that originally earned the nickname.
Rumney, NH
Glacial boulders piled against one another here to form narrow passages, chambers and squeezes with names such as the Lemon Squeezer and Devil's Turnpike. Unlike a traditional limestone cavern, these "caves" are spaces between enormous granite blocks left by glacial activity. The attraction is ticketed and seasonal.
Amherst, NH
A boardwalk enters a floating bog landscape filled with sphagnum, pitcher plants, sundews and other species adapted to acidic wetland conditions. The environment can feel more like a northern peatland than suburban southern New Hampshire. Visitors should remain on the boardwalk to protect the fragile habitat.
Manchester, NH
A bronze statue of inventor Ralph Baer sits on a bench in Arms Park near the Manchester mill buildings where he developed pioneering home video-game technology. Baer is widely credited as the "father of the video game" for work that led to the Magnavox Odyssey. Visitors can sit beside the life-size figure overlooking the Merrimack River.
Warren, NH
A full-size Redstone missile stands improbably in a small New Hampshire town park. The missile type was originally developed as a ballistic weapon and later adapted to launch Alan Shepard, the New Hampshire-born first American in space. Its towering presence beside ordinary village surroundings makes it one of the state's strongest roadside oddities.
Groton, NH
The Cockermouth River has carved deep potholes, bowls and smooth twisting channels into the bedrock here over thousands of years. The shapes look almost intentionally sculpted, which gives the gorge its name. The state natural area is generally open for recreation, though conditions can become hazardous around high water and ice.
