Attn: Hours for the Niagara Cave vary depending on what time of year you visit.  April: Saturdays and Sundays 10:00 - 4:30 May: Weekends 10:00-4:30 Mon-Fri Tours @ 11:00, 1:00, 3:00 & 4:30 Summer (Memorial Day - Labor Day): Daily 9:30-5:30 September: Weekends 10:00-4:30 Mon-Fri Tours @ 11:00, 1:00, & 3:00 October: Weekends 10:00-4:30 Thurs & Fri: Tours @ 11:00, 1:00, & 3:00 Niagara Cave is one of the most fascinating and unique geological attractions in the United States. In fact, it has been rated one of the top ten caves in the United States by many outdoor activity rating sites! During the one-hour, one mile, guided tour visitors will witness an underground stream leading to a waterfall nearly 60 feet high, stalactites both delicate and massive, calcite flowstone, several fossils that have been dated to over 400 million years old, and a wedding chapel in which over 400 weddings have been performed, plus much, much more. Niagara cave is a constant 48 degrees year around, so a light jacket or sweatshirt is suggested. Proper walking shoes are required, (flip flops and Crocs are not recommended) High heels and bare feet are not allowed. Also, because there are several sets of stairs on the cave tour wheelchairs and strollers can not be used on the tour. However, the gift shop is wheelchair accessible. If you have a heart condition, have difficulty taking stairs, have severe asthma, or any condition that may hinder your ability to walk one mile and descend and climb a total of 250 stairs in a cave environment with high humidity, we do not recommend that you take the tour. Niagara Cave is not a bat habitat.

Niagara Cave is also home to the Crystal Wedding Chapel where couples can have their wedding ceremony in the deep underground caves. Since 1934 they've held over 400 weddings in the little chapel overlooking the amazing waterfall!

We arrived early and did their mini golf. Cute gift shop. Bathrooms in gift shop. We've done a lot of cave tours and this one was different as it was much more narrow and it had the waterfall in it and a tiny chapel set up for those who want to get married. Lots of stairs. Repeat! Lots of stairs. Gets cold so definitely wear a sweater and pants. Property was very well kept. Beautiful wildflowers greet you at the entrance. Knowledgeable and nice staff.
