Construction Projects

Mammoth Cave Hotel Roof Replacement Project

The Mammoth Cave Hotel Roof Replacement Project began on Monday, December 6, 2021. The main building of the Lodge at Mammoth Cave Hotel is open for commercial visitor services, such as the Lantern Cafe, retail, and the hotel check. The Green River Grill is anticipated to re-open in March, 2024. The project is funded through the Great American Outdoors Act (GAOA) and will help address the park’s backlogged maintenance needs and correct other exterior and interior deficiencies of the park’s main hotel building.
