Welcome to the new Cave-Exploring website. I plan to add more information and resources over time. For those folks who are used to the old site, every page has been updated with the latest links and information.

Tennessee has a cave that’s currently sitting at 58 miles of surveyed passage and it’s no longer a secret. It has the potential to hit hit 100. There are numerous other caves that have been surveyed over 1 mile that are not on the list. I enjoy the site and know it’s a work in progress that will never be complete because of the nature of cave exploration and survey.
I know there are many caves not on the long and deep list as posted. I generally wait until getting official data from the project coordinators, state cave surveys, or other sources to add things to the list. I will also update the list when the projects post information on Facebook or other social media. My policy is not to “scoop” official project announcements even if I am aware of them.
Thanks for checking out the site and good luck on your caving adventures.

Thank you very much. I’ve put the information into the database and it will be in the next updated list.

I did a search of ‘West Virginia’ today July15,2026 to see if any of the caves I have been in are on the list. Friar’s Hole is and it is longer now than I recall when I was there. I’ve been to Ellison Cave a few time, even did a through trip once. I did not know there was a cave in West Virginia with the same name? But maybe there is? Thanks for doing the web site BTW.
As of September 23, 2026, the 25th expedition to the Shuanghe Cave System recorded a surveyed length of 481.5 kilometers and a depth of 912 meters, with 124 connected entrances—an increase of 41.8 kilometers and nine entrances compared to the 24th expedition. Additionally, 436 unconnected entrances were identified, with a combined length of 165 kilometers; the number of such entrances increased by 25 compared to 2025.
Breakthroughs have also been achieved in paleontological surveys, with the discovery of remains belonging to nine giant pandas, one antelope, one rhinoceros, and one *Stegodon* (an extinct type of elephant). Additionally, a tapir skeleton and a clouded leopard skeleton were unearthed, and two sets of giant panda claw marks were found within the cave. The tapir specimen is a juvenile with a well-preserved skeleton. This marks the first time skeletal remains. of tapirs and clouded leopards have been discovered in the Shuanghe Cave System. To date, remains representing a total of 61 individual giant pandas have been found.
