We arrived about 7:05 pm, there were several people already there. We saw maybe 3 bats as they flew up by us. We stayed until 8;05 everybody had left but us but the bats appeared to have left from another exit. Which I wouldn't blame them. The host kept answering questions throughout the whole hour, there were noisy kids that... More

So much better than I expected. Pay the $5 fee to go down below. Good talk by the ranger, and then the bats came out. They do this cool circular thing building up height to clear the trees then fly off for miles and miles. The population had recently dropped from 3 million to 800,000 as the bat started heading...

Went there during the day/ no charge if you are not watching the bats. Really neat to see the old tunnel but it's a short steep hike to the bottom.

We went on Labor Day weekend - was really crowded, and we arrived too late to go down to the lower level to get closer to the cave. But that was okay, because the smell would have probably been too much. We saw plenty of bats come out, and in fact, they also emerged from the north end. Enjoyed the... More

Fun for a great price. We went to lower level and paid the 5.00. The bats came out early around 845 pm so we were done by 915. We didn't wait for all of them to come out because it is a good walk back up the hill and not well lit. Was worth the 5.00. Like the information the... More

We paid the small fee to go to the bottom where the bats actually come out of the tunnel right over you! I actually felt one sweep right over my head! The park ranger comes and talks to you and answers questions before the bats come out each night. You can even go early and walk to the bottom of... More

Wow! Such an incredible sight to see if you have never been before. We drove up to the state park around 5:30pm. Upon arriving we were greeted by two very friendly and knowledgable park volunteers. They informed us about all of the different types of bats to see, history of the park, and so on. We luckily got there just... More

this was so cool - be sure and call the number to find out the emergence time & be there an hour ahead to get a seat - you cannot imaging what it is like for 3 million bats to emerge but it is awesome.

Experienced a fun evening- even with lightening, thunder and a major down pour of rain. We arrived at 6.30, and paid our "donation" to sit in the lower seating area. The road down to the tunnel was still open, so we quickly walked down to take a look and then back up to get some seats. A very knowledgeable volunteer... More
