This Lake Erie island has the world’s largest geode tucked under a winery’s floor

It’s three miles off the mainland

Put-in-Bay sits on South Bass Island in Lake Erie, just three miles from Port Clinton, Ohio. The island stretches 3.5 miles long and 1.5 miles wide, covering 1,382 acres.

You get there by ferry, either Miller Boat Line or Jet Express, and once you step off the dock, golf carts take over. Rentals line the harbor.

Vacationers have come here for over a century, and the island keeps pulling them back. The history alone goes deeper than you’d expect.

A War of 1812 battle launched from this shore

South Bass Island landed on the national map during the War of 1812.

On Sept. 10, 1813, Commodore Oliver Hazard Perry sailed from the island and defeated a British naval squadron in the Battle of Lake Erie. That single day changed the course of the war on the Great Lakes.

Peace followed, and by the mid-1800s, the island had shifted from battleground to resort town. Today, tourism drives the entire economy, and traces of that fight show up everywhere you look.

A 352-foot column honors three nations at once

Perry’s Victory and International Peace Memorial rises 352 feet above the island, the tallest Doric column in the world. It’s also the only international peace memorial in the U.S. National Park System.

Built between 1912 and 1915, the column honors those who fought in the Battle of Lake Erie and the lasting peace between the United States, Great Britain and Canada.

Six officers killed in the battle rest beneath the rotunda floor, three American and three British. All three nations’ flags fly at equal height beside it.

The column’s closed, but the story isn’t

The memorial column and observation deck closed in March 2026 for a major restoration funded by the Great American Outdoors Act. Construction runs through November 2027.

But the visitor center and surrounding grounds stay open, and you won’t pay a dime.

Inside, you’ll find exhibits on the Battle of Lake Erie and the War of 1812, a 15-minute film, and ranger-led programs that walk you through the full history. Plan around the closure, not instead of it.

Dig a well, find the world’s largest geode

Forty feet beneath Heineman’s Winery sits Crystal Cave, the world’s largest known geode. Workers stumbled onto it in 1897 while digging a well.

The walls are covered in celestine crystals, a pale blue mineral, with some stretching up to three feet wide. Heineman’s has been making wine here since 1887, the oldest family-owned winery still running on the island.

When Prohibition shut down all 17 other island wineries, Heineman’s survived by opening the cave to tourists and selling unfermented grape juice.

Perry’s Cave stays 50 degrees all summer long

A natural limestone cave sits 52 feet below the surface at Perry’s Cave Family Fun Center, registered as an Ohio Natural Landmark.

Commodore Perry reportedly drew fresh water from it during the Battle of Lake Erie back in 1813. Guided tours run 15 to 20 minutes through a single room that measures 208 feet long and 165 feet wide.

It holds at about 50 degrees year-round, so you get a break from the heat.

Above ground, the Fun Center adds mini golf, gemstone mining, a rock wall, a giant maze and an antique car museum.

Walk through 50 species of butterflies

The Butterfly House opened in 2004 inside a 4,000-square-foot tropical greenhouse at Perry’s Cave Family Fun Center. More than 50 species from around the world fly freely through flowering gardens and winding pathways.

Soft music plays in the background. You walk at your own pace with no time limit, and the butterflies land wherever they want, including on you.

A butterfly-themed gift shop sits just outside the exit if you want to take something home besides the memory.

A burned hotel and a rescued snake

South Bass Island State Park lines the southern shore with camping, a stone beach, a fishing pier and picnic areas. Ancient ice sheets carved glacial grooves into the dolomite bedrock here, and you can still see them.

The ruins of Hotel Victory, once one of the largest hotels in the world before fire destroyed it in 1919, sit on the grounds.

The park is also home to the Lake Erie watersnake, a species found only on the Lake Erie islands. It was once federally threatened but recovered enough to come off the list in 2011.

A live beehive inside a giant replica tree

The Lake Erie Islands Nature and Wildlife Center focuses on conservation and education about the island’s plants, animals and habitats.

Inside, you’ll find more than 200 taxidermied specimens of mammals, birds and fish native to North America, plus an indoor turtle pond and a live observation beehive built into a large replica tree.

Outside, nature trails lead past a frog pond and butterfly gardens.

Every summer, the center runs Wild Tuesdays with hands-on programs led by regional wildlife experts.

Wildflowers bloom on trails most people skip

Massie Cliffside Preserve covers 11 acres on the eastern point of the island, right along the Lake Erie shoreline.

Jane Coates Wildflower Trail loops half a mile on the southern end, connecting three acres of woods to the Ladd Carr Wildlife Woods.

Wildflowers peak in April and May, and migratory birds fill the canopy through spring and summer. Dodge Woods Preserve, near Perry’s Cave, opens daily from dawn to dusk.

All the preserves are free and public, a quieter side of the island away from downtown.

DeRivera Park sits right on the harbor

Downtown Put-in-Bay is walkable. Shops, restaurants and waterfront views cluster around the harbor, and DeRivera Park anchors the middle of it all with fountains, shade trees and benches overlooking the water.

Behind Town Hall, the Lake Erie Islands Historical Society Museum fills more than 6,000 square feet with exhibits on island history, the War of 1812, winemaking and Victorian-era tourism.

Founded in 1975, the museum screens a free history film and rotates artifact displays. A heritage resale shop on the grounds sells donated items, with proceeds going back to the museum.

You can cross the whole island in 10 minutes

Golf carts rule here. Multiple rental companies line the downtown ferry docks, and a cart gets you to most attractions in under 10 minutes.

The Put-in-Bay Tour Train runs a narrated, open-air loop around the island and works as a hop-on, hop-off shuttle between stops. You can also bike, grab a taxi, or just walk.

One thing to know: on weekends and holidays, day-trippers can’t bring personal vehicles onto the island without proof of an overnight stay.

Catch the ferry to Put-in-Bay, Ohio

You can reach Put-in-Bay by ferry from Catawba Island or Port Clinton, Ohio.

Miller Boat Line runs from Catawba with the lowest fares and most frequent trips, about 20 minutes each way. Jet Express runs high-speed service from both Port Clinton and Sandusky.

Most attractions open from May through September, with some staying open into October. The island sits about halfway between Toledo and Cleveland in northwest Ohio.
