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.
Paris Springs, MO
This lovingly recreated 1930s Sinclair station became internationally known through the hospitality of the late Gary Turner and remains a major Route 66 pilgrimage stop. Vintage pumps, signs, vehicles and roadside memorabilia recreate the atmosphere of the Mother Road's service-station era.
Thayer, MO
Grand Gulf is a collapsed cave system often described as Missouri's 'Little Grand Canyon.' Visitors can view the deep chasm from rim trails and, when conditions allow, descend designated routes into portions of the natural feature.
Alton, MO
Greer Spring is one of the largest springs in the Ozarks, releasing an enormous volume of clear water that quickly forms a substantial stream. A roughly one-mile trail descends from the public parking area to the spring branch.
Camdenton, MO
The Colosseum is a huge collapsed sinkhole, roughly 150 feet deep, created by the same karst processes that shaped Ha Ha Tonka's caves and natural bridge. The feature is reached from a signed state-park trail rather than by entering the collapse itself.
Camdenton, MO
This massive natural limestone bridge is one of several karst features concentrated inside Ha Ha Tonka State Park. A maintained trail reaches the arch and makes it an easy addition to the nearby castle ruins and spring.
Camdenton, MO
A large blue spring emerges at the base of the Ha Ha Tonka bluffs and feeds a clear stream toward the lake. Boardwalks and trails connect the spring with the park's other geological features and historic ruins.
Sycamore, MO
Hodgson Mill stands dramatically at the base of a bluff beside a powerful spring that once drove milling machinery. The privately owned building is best treated as a roadside exterior/photo stop unless current access information specifically permits more.
Marshfield, MO
A one-quarter-scale, roughly 1,200-pound replica of the Hubble Space Telescope stands near the Webster County Courthouse in astronomer Edwin Hubble's hometown. The outdoor monument turns a complex spacecraft into an easy roadside science-history stop.
Versailles, MO
Jacob's Cave offers guided walking tours through a large Ozark cavern filled with reflective pools, columns and other formations. The cave has operated as a tourist attraction for decades and remains a dependable central-Missouri subterranean stop.
Middle Brook, MO
The East Fork of the Black River is squeezed through resistant volcanic rock here, creating chutes, potholes and cascades known as shut-ins. Designated public access makes this one of Missouri's most dramatic routeable geological stops.
Pierce City, MO
Jolly Mill survives from the vanished community of Jollification and has served at different times as a mill and distillery. The restored mill stands inside a public park with seasonal grinding demonstrations and an unusual local history tied to Civil War-era violence and Ozark folklore.
Kansas City, MO
The parking garage of the Kansas City Public Library is disguised behind a row of enormous book spines selected with community input. The oversized titles turn an otherwise utilitarian downtown structure into one of Missouri's most recognizable pieces of literary street architecture.
Eminence, MO
Klepzig Mill is a small historic turbine mill beside Rocky Creek in the Ozark National Scenic Riverways. The remote structure, shut-ins and creek setting create a strong backroad OddWay stop, but access roads can be rough after bad weather.
St. Louis, MO
More than 100 acres of woods and lawns hold large-scale contemporary sculptures, including monumental works that can be walked around and through. The free outdoor collection makes an easy OddWay cluster of strange objects rather than a single conventional gallery visit.
Ridgedale, MO
Lost Canyon is explored by self-driven golf cart along a constructed nature trail that passes waterfalls, rock formations and a cave containing an underground bar. It is highly developed, but the unusual cave-drive format earns it a place in the OddWay database.
Hannibal, MO
Known to Samuel Clemens as a boy and later woven into The Adventures of Tom Sawyer, Mark Twain Cave is Missouri's oldest continuously operating show cave. Guided tours explore its maze-like passages while connecting the geology directly to Hannibal's literary history.
Branson, MO
Marvel Cave was the original attraction around which Silver Dollar City developed and contains one of the largest cave entrance rooms in North America. Theme-park admission includes scheduled cave tours that descend hundreds of feet below the surface before returning visitors by cable train.
Sumner, MO
Maxie is a roughly 40-foot-tall Canada goose sculpture with a wingspan of more than 60 feet, built as a monument to Sumner's identity as a goose-hunting and migration town. The giant bird stands in a public park and is an easy northern-Missouri photo stop.
Stanton, MO
Meramec Caverns is a large commercial cave system beneath the Ozark hills that has drawn Route 66 travelers for generations. Guided tours pass through extensive limestone rooms and formations, with the attraction also trading heavily on regional Jesse James lore.
Ironton, MO
Mina Sauk Falls drops in a series of cascades down Taum Sauk Mountain and is generally considered Missouri's tallest waterfall. Its flow is seasonal, so the rugged trail is most rewarding after wet weather.
Washington, MO
Missouri Meerschaum has manufactured corn-cob pipes in Washington since the nineteenth century. Its small museum and shop interpret the unusual local industry beside the still-active factory, while factory production areas themselves are not a public tour.
Salem, MO
Multiple large springs rise inside Montauk State Park and combine to form the headwaters of the Current River. Trails and historic mill features make the spring area a strong natural-history stop rather than simply a fishing destination.
Leasburg, MO
Onondaga Cave contains a dense concentration of stalactites, stalagmites, flowstone and large rooms beneath its namesake state park. Missouri State Parks offers scheduled guided tours during the 2026 cave season.
Kaiser, MO
Ozark Caverns is an undeveloped cave at Lake of the Ozarks State Park where tours rely on hand-held lanterns instead of installed electric lighting. Angel Showers, a formation created by water falling from the cave ceiling, is one of its signature features.
