The Largest Cave In The USA Will Blow Your Mind

We journeyed into the cave with the largest underground room in the USA. It wasn't easy but it was so worth it seeing this place.

It is so loud in the And Me and Alex went on a long journey to somewhere and never found a dead end.... We just finally decided to turn around and come back.

Caves like this really make me wonder about the ones that are yet to be discovered

At 64 y’all make me miss my youth! Thank you for sharing this! Enjoy life to its fullest and keep practicing your safety!

The views of them repelling down in the big light really shows how massive the room is. Absolutely incredible. Thanks for sharing.

When I see massive underground water systems I think unknown things are going to come up and eat me.
I have always been in love with the feel of a cave and all of its mysteries. Now I can explore without leaving my house 😂 thanks guys for such wholesome content

Viewers take note. The current pulling someone in the water as they swim is an undercurrent. Still water can be deceiving and dangerous.

You guys should start carrying laser pointers with you for scouting out long linear spaces. Probably would work better than a flashlight for things like that water tunnel after the swim. Once the laser hits a wall, the light will bounce and light up the surrounding space as well.

These are some of the best caving videos on YT. Never was into vertical stuff, but did quite a bit of crawling and squeezing in tight spots. I’m 51 and my night vision has degraded to the point that it’s no longer safe for me to be underground. Thanks for taking me and others along on your adventures

[chrisjones]

Good lighting, camera quality, and shots as always make you the best caving channel on YT. I also like the clean commentary so my kid can watch it too. thanks guys and be safe!

[socomxx]

Great video man, I love how you go the extra mile, even though when things look creepy, just kept pushing. Hopefully ya'll get sponsored or something so you can travel the world exploring caves.

Hey lads I’ve done some real minimal caving in Lancashire, England I was in the army and it was an easy cave, nothing like what you lads are doing.
I have had to go up through a waterfall as part of an outdoor climb.
I climbed around 3/4 meters up and through a waterfall it’s an intense experience, I think I didn’t feel fully in control was the fear I guess feeling got to me, so underground sending props from Aberdeen, Scotland 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇺🇸

MASSIVE and SPECTACULAR experience! That would be terrifying beyond belief! You guys certainly bring the amazing, hidden wonders of this world to life! At times, it's kind of difficult to imagine the scale of these secret places until you add the human element into your camera shots! What I wouldn't give to be young enough to share in the subterranean dreams that you guys call reality! Not even Jules Verne could have imagined adventures as incredible as the ones brought to the surface by your teams! Thank You for another unforgettable journey down into the darkness!!!!

According to Wikipedia, Carlsbad Cavern includes a large limestone chamber, named simply the Big Room, which is almost 4, 000 ft (1, 220 m) long, 625 ft (191 m) wide, and 255 ft (78 m) high at its highest point. The Big Room is the largest chamber in North America and the 32nd largest in the world.

Dude that was scary watching you get in that murky water, you had no idea what kinda potential underwater currents were in that water that possibility could have easily pulled you under, be careful with deep water like that please

[christophermccall]

You are living the dream. It’s amazing to see these caves that most people will never see. I hope you will travel outside America would love to see what else is out there

I used to go caving when I was younger 60 years ago, we had food, extra thermal underwear and a wool blanket with us and used to stay the night over. There is nothing darker and more peaceful than spending a night in a place that was hundreds of feet below the surface and a mile + away from the entrance.

[anthonyrussell]

I always love that idea of from a tiny hole in the ground you can come to these wide open spaces. Who's to say there aren't other massive undiscovered caverns here in the US

[Cduff]

I don’t think I really appreciated the size of this room until the clip of your Buddy rappelling down, absolutely cathedral sized room in such an unsuspecting cave!

[mayw]

That is spectacular! What an incredible place, I cannot *believe* how big it is. Thanks for showing the rest of us!

[williampacey]

Good grief that is one monstrous cave. You guys kill it every time. Great video.
