Dark Sky Week at Mammoth Cave National Park

April 15, 2023 - April 22, 2023

Mammoth Cave National Park invites you to celebrate International Dark Sky Week with ranger guided walks, talks, and special evening programs.
International Dark Sky Week (IDSW) is an annual event held during April’s new moon, that encourages people worldwide to turn off lights and enjoy the night sky without light pollution.
Mammoth Cave National Park was recognized as an International Dark Sky Park by the International Dark-Sky Association (IDA) in 2021. The park is committed to preserve the night sky’s beauty and share it with future generations.
During the IDSW programs visitors can view deep sky objects and constellations through telescopes, take a nighttime walk on a park trail to learn about nocturnal wildlife, and even get a closer look at our nearest star, the Sun. Most of the programs will take place in the evening hours but there will be two daytime events during the week at the visitor center.
Check the Mammoth Cave Events Calendar for a list of daily activities.
All events are weather dependent and free and open to the public with no tickets or reservations required.
