Mammoth Cave National Park participates in the congressionally authorized Federal Recreation Lands Enhancement Act. Under this program, parks keep 80% of all fees collected; the remaining 20% is deposited in a special account to be used in parks where fees are not collected. Funds generated by the fees are used to accomplish projects the parks have been unable to fund through annual Congressional allocations. Entrance fees help support projects in the park to improve the experience for visitors. For more information, call (270) 758-2180.
