This is like a different world This cave entrance may be beautiful, but looks can be deceiving We didn't know it yet, but the next seven days will by far be the hardest of our entire lives All right, it's gonna get dark in a couple hours if we don't have a camp we're screwed Okay, do you have any idea where you're going?

We're just looking for flat ground to set up camp upon entering the mouth of the cave We stumbled upon an area with high enough elevation to protect us from any flash flooding meaning that it was perfect for camp Perfect is a crazy word good enough is what I would use good enough for camp We spent the rest of day one grabbing our supplies that we were dropped with each one of these bags weighs like 80 pounds And as you can see by the footage we spent around four hours.

This is very hard to traverse Getting all of it back up to our base camp.

All right We've got some lights on in here.

Our supplies are finally at our home base And if you point the camera over there You'll see it's pitch black It took all day.

And so we set up the bare minimum for camping grounds.

We drilled holes to hang up some ropes Grab these pull yourself up Looks like the ropes will be able to support hammocks and with the help of our survival guide joel We hung our hammocks this thin rope is what holds up my hammock Yeah ate some dinner and prepared for a very cold night one Not gonna lie.

This hammock is uh way more comfortable than I thought it would be.

Hey Oh god, why is my head so big bro?

This part of the cave is two and a half kilometers deep and we're basically camping at the entrance tomorrow We have a lot of exploring How'd you guys sleep?

Horribly.

I didn't.

It's a very perplexing environment.

The cave's constantly dripping water on us from above So we put a tarp over us, but even still the water's dripping into our hammocks.

I have an idea Let's make our shelter actually good.

I say we connect these tarps so we stay dry while we're sleeping.

That's literally genius I'm, not just a youtuber.

Okay, my hammock gets out right here Are we serious right now?

This is where I just got out of bed and we didn't realize it at the time But this hole is almost 40 feet deep So while shawn and I got started on the super tarp mac and carl went to see how dangerous this hole was for themselves Do you see my hammock up there?

That is where I slept now Look at this and because everything looks the same and it's probably pretty hard to follow us in this cave On this map you can see our home base and how far they're moving away from it.

All right, it's been real bro.

Oh, bro This is crazy.

While the boys are randomly exploring me and shawn actually have to work on the camp Why is there a sleeping bag over here?

Uh, because it smelled like pee Ew.

Lesson number one.

Don't rent your sleeping bags.

Why did we rent sleeping bags?

Why did we not just buy sleeping bags?

We're zip tying the tarps together to create one mega tarp.

Don't mind me just Trusting this rope with my life and meanwhile mac and carl were still in a hole.

Oh my god And eventually they finally made it to the bottom We're supposed to be working on camp We just wanted to show how dangerous camp was just don't fall.

It's a skill issue Oh, okay, and even though they should have been on their way back carl and mac insisted on seeing how deep they could go Bro, this just looks so crazy.

You think you could make it through the river?

But little do these two know this river actually runs throughout the entire cave, which means we'll be spending some time in it Oh, there they are Tell me you guys cooked.

Oh, we cooked.

That's right a new home.

Am I right?

Let's go.

We now have a roof Look at this.

I'm not gonna lie.

You're actually kind of gross and we moved the fire pit to this little cove we found What do you think?

It's warmer.

It's cozy.

These rocks trap the heat here and block the pee from the rocks above It's not pee.

What do I call it?

I don't know maybe rain or something, but it's not rain.

It's rock Point it up.

Do you see clouds?

No, you see rocks.

It's not rain rock pee rock pee Rock pee fine.

All right, it's rocky and after a much drier night of sleep We decided to have joel our survival expert help us get all the way to the end of the cave cave Cave cave cave cave Let's see how deep in the cave we can make it now keep in mind We are still just at the beginning of this massive cave and our goal is to make it all the way through it Without dying, of course.

Oh my gosh.

This is kind of steep, bro.

You ain't seen nothing yet We're going deep in the cave.

All right, boys sucking you guys where things get tight I don't actually think i'm gonna fit the interesting part about cave exploration is one second You're barely fitting through cracks in the rocks.

Oh my god And then the next you're in a massive chamber so big that in order to see it all we had to do this Oh my god, I can actually see now.

This is awesome.

This thing is bright Wow, look at how cool this is.

Yeah So bright I can't even look at it.

I'm like getting blinded.

Oh, no Oh, no in hindsight.

We probably didn't use that the most effectively lead the way and so we continued on There's a really good handle up the top there and then you can sort of swing a foot around onto this one like this Yeah, yep.

Perfect.

Joel the best caving guide ever No one's died yet All right, guys, this is where things get interesting.

What?

What is this?

So from this point on wet suits We're going for a swim yesterday mac and carl were joking about doing this But the rest of this cave adventure takes place in a freezing river Oh my god, this is insane meeting wet suits are the only way to not get hypothermia.

Why are we doing this?

This is a once in a lifetime experience because you die after you do it So in order to get to the end of the cave We have to hop in this river and fight the rapids through this tiny hole in the rock And carefully squeeze our way through it.

Take your time.

It will take your feet behind you a little bit All right, i'm getting in the river follow follow the wall around.

It's so cold You got it jimmy I don't know if I fit jimmy.

I need you to pull yourself up out of the water.

Oh my god What's crazy about doing this?

Oh, it's so cold is when you're completely submerged in freezing cold water gripping onto the rocks becomes incredibly hard Oh my gosh, that was crazy And even though this obstacle was difficult it's nothing compared to what's up ahead We're now 10 done Which means we've only scratched the surface of this expedition and we still have over two kilometers remaining to reach the end As you can see it rains in this cave 24 7 So i'm making a chill spot for us to hang out in and not get wet I wonder what it would look like if I wasn't here to build all this Pretty sure they'd just be sleeping in a pile on a wet rock Why is this so difficult Ah The worst part is every inch we go this way Is an inch we got to go that way to get back to camp our next obstacle may be out of the water But that doesn't make it any easier to get through.

Oh, is that a spider web?

Why not?

I don't see a spider.

That means it's probably on us.

It's on you.

It's on you.

I hate my friends This cave is like a Mr. Beast video The further you go the harder it gets just straight up if we didn't have joel I'd be dead and after three hours.

Joel had some bad news for us.

The water's too high and we've taken too long We're gonna have to turn around for today and head back to camp.

I disagree.

You can't disagree with the safety expert.

I disagree Well, we can't really disagree It turns out we wasted way too much time filming and playing with flares to the point where we now had to restart And attempt this mission another day Sean we're back What'd you do while we were gone?

Hopefully nobody gets wet now, but I didn't even know we packed lights.

Yeah, they're awesome, right?

Sadly, we only made it 20 through the cave today, but mark my words.

We will go the distance in a future day I doubt it That's not gonna happen We might rest on day four and then on day five try to go all the way to the end of the cave and see what's There day three was a lot of fun.

I'll see you guys tomorrow And After a third miserable night in the cave the next morning We only had one thing in mind a hot shower would literally save my life right now.

Oh showering would be awesome I haven't showered in three Four days as you can imagine showering inside a cave isn't easy We had to hike all the way back to where we rappelled in to safely reach the riverbed I feel my brain.

I've never felt my brain like this.

My forehead is frostbite Let's use the drone to dry our heads off.

Come here drone stop stop.

It's actually working Yeah, it is working who needs a hairdryer when you have a drone and after we dried off We sat down with joel to plan our journey.

What is this?

Joel, this is the map of the cave last time we had to stop because of the fast moving water But the rains have been slowing so we might just get a window to reach the end by tomorrow Dude, this is about to be wild first We'll need to pass some of those same rapids from yesterday dive off massive cliffs and avoid jagged rocks And if we can make it past all that we will finally make it to the beautiful glowworm chamber Don't tell us what that looks like.

I want us to be surprised.

Do you think we're gonna make it?

Nah, let's not play that game.

We're all gonna make it with tomorrow's plan thoroughly mapped out We rested up and made feastable s'mores to regain our energy everyone's cheers Oh, joel's about to have his first feastable s'more.

All right, joel be honest Joel approves.

Joel approved.

Why didn't we whip this chocolate out earlier?

This just got like 10 times more fun guys for real If you've never tried s'mores with feastables, you're really missing out tomorrow.

We're gonna explore the entire cave We'll see you guys then So we tried to sleep as much as we could and prepare for tomorrow's journey to the end of the cave We're about to embark on one of the most dangerous journeys of my life because of our experience from day three and focusing less On filming we were able to make progress way faster This water's cold just like the other day, bro Easy and to ensure our best chance of survival in addition to joel We brought another survival expert with us.

This is where we had to stop on day three.

How we doing?

We're making much better time behind us.

It's pitch black.

Where do we go?

That's the area gets narrow the current's strong.

So we're going to use the walls and kind of climb our way along.

Yep Here we go.

I got it.

Oh god jump for that first rock There's a couple of good rocks around the corner as well.

You can get a hand on too It's so dark down here, there's no water right now My feet aren't touching the ground right now because we couldn't reach the ground This meant that if we let go now we could get swept away by the strong current directly beneath us joel What are we doing?

I'll go into here if you can.

That's a good one.

I can't even see where i'm going The current is taking me away.

You got it.

You gotta get yourself in there and it's gonna get way gentler.

I go in here?

Yep In the hole Yeah, well done well done.

This might be the most insane thing we've ever done We are much deeper in the cave than we've ever been and we're now approaching our first serious obstacle Basically the water's recirculating So if you fall in it takes you to the bottom and it keeps you there.

If we fall we would die.

Yeah Okay, so death is on the table.

This is just not what I thought I was signing up for Come on Yeah, perfect Yeah, correct Oh, yeah Caving it's a lot harder than I thought you can tell how strong this river is because it created this entire cave and fun fact We're not as strong as a cave.

I'm barely as strong as a human Well, fortunately for us rather than carl leading this expedition We've got the literal avenger joel and just to prove how much of an expert he is This man literally flexed on us by jumping off a cliff Oh my god You're crazy This is a bit crazy.

Surely one of you guys are keen.

I'm crazy.

No shot.

You want to do that?

What are you talking about?

I'm doing it right now, baby.

Let's go.

Don't god speed back after everything jimmy's put me through This ain't that scary for me three two one Oh No, we got to keep going or we will hit the end Oh my god Can we go downstream why are we always fighting the current I might just start drifting away I might just give it up There are sharp rocks underneath the water.

You cannot see them.

So watch your step.

Oh my god, it's getting deep again I can't I need to put my feet up and if the sharp rocks weren't enough of a challenge It seemed like with every step we took Oh, bro, I can't see anything.

This is terrifying the caves became darker tighter And ruthless enough that we began to question if we could even get to the finish line It's awesome this cave is about to get a lot harder and I have something I need to show all of you joel Can I see your bag?

Thank you.

You know what you've been carrying.
