Found in County Fermanagh, Northern Ireland, Marble Arch Caves are an already-popular site thanks to its otherworldly limestone formations. But visitors to the cave can also experience its ancient wonders in a unique way: a cave cruise.

Erne Water Taxi and Marble Arch Caves collaborated to create an adventure this year in celebration of the caves’ 40^th anniversary and Erne Water Taxi’s 10 years operating on Lough Erne. Travelers can climb aboard eco-friendly Island Discovery, which enters the caves via a guided tour. The trip departs from Enniskillen Castle Museum’s jetty, with guides sharing stories of local history and folklore, traveling 12 miles to the caves.

Traversing underground rivers, travelers will witness stalactites, delicate rock formations and more on this 60- to 75-minute tour.

A Virtual Reality Cave Explorer Experience is also available at the visitor center for travelers with accessibility needs.

“This collaboration highlights the best of Fermanagh’s natural beauty and eco-tourism efforts,” said Barry Flanagan, owner, Erne Water Taxi. “The Island Discovery offers a sustainable way to explore Lough Erne while learning about our unique island town. We’re delighted to be part of this incredible experience.”

The  experience also coincides with Tourism Ireland’s new global campaign, Ireland Unrushed, which encourages travelers to slow down and immerse themselves in the peace of Fermanagh.
