Cathedral Cave Off-Trail Tour

at Onondaga Cave State Park

6/6/2026 | Onondaga Cave State Park | Leasburg, Mo.

Onondaga Cave State Park is hosting a series of off-trail tours of Cathedral Cave again in 2026. These tours are perfect for beginning cavers who want a more intense cave experience, one that goes beyond the lighted tour with rails and trails. Each tour is led by an experienced guide who will provide general instructions and share information about the cave's biology, geology and history. During the tour, participants will climb, crawl and get a little muddy. They will spend four to five hours in the cave and some additional time outside the cave.

Each tour is limited to 15 people aged 13 and up. Paid registration is required. The fee is $75 per adult and $55 per youth. All interested guests will be asked some questions to determine whether they are able to complete the tour, and they will be shown a video of what to expect inside the cave. After registering, they will receive a list of items to bring. Caving helmets will be provided.

To register, call the park at 573-522-3760. Tours begin at 10 a.m. on the dates listed below. Meet at the park visitor center, located at 7556 Highway H in Leasburg.
