Park Modifying Operations to Implement Latest Health Guidance

Mammoth Cave National Park is announcing modifications to operations to implement the latest guidance from the White House, Centers for Disease Control & Prevention (CDC), and local and state authorities to promote social distancing. Where it is possible to adhere to the latest health guidance, hiking, equestrian, and biking trails will remain open and accessible to provide healthy options for the public.

The health and safety of our visitors, employees, volunteers, and partners at Mammoth Cave National Park is our number one priority. The National Park Service (NPS) is working with the federal, state, and local authorities to closely monitor the novel coronavirus (COVID-19) situation. We will notify the public when we resume full operations and provide updates on our website and social media channels.

The NPS urges visitors to do their part when visiting a park and to follow CDC guidance to prevent the spread of infectious diseases by maintaining a safe distance between yourself and other groups; washing your hands often with soap and water for at least 20 seconds; avoiding touching your eyes, nose, and mouth; covering your mouth and nose when you cough or sneeze; and most importantly, staying home if you feel sick.

For high-risk populations, such as the elderly and people with underlying conditions, we ask that they take extra caution and follow CDC guidance for those at higher risk of serious illness.

Updates about NPS operations will be posted on For information on cave tour ticket refunds at Mammoth Cave, please contact the park’s fee office at 270-758-2417.

Additional projects in the Green River Ferry day-use area include the construction of a new canoe and kayak launch site and a foot bridge on the Echo River Springs Trail. Some closures may occur due to construction in this area of the park.

Mammoth Cave Trail Rehabilitation Project

The Grand Avenue and Wild Cave Tours are temporarily closed. The trail work will improve the walking path, stairs, handrails, seating and resource issues along approximately two miles of trail. The entire project is scheduled to take 18-20 months to complete. Other tours in the park are open to visitors as usual.

Several roads and parking areas on the south side of the park are undergoing repaving. Drivers may experience minor delays during the project. The pavement preservation project is being coordinated by the United States Federal Highway Administration and National Park Service and will extend the life of the paved areas throughout the park that will be resurfaced during this project.
