My Grandad showed me these tunnels when I was young. We didn't go far into them as we had no lights. Great fun following you guys and thanks for sharing it.

The tunnel complex within Dover is amazing! Nice to see Steve & ray bck . 👍

I remember going into some of these tunnels 60 years ago and eventually got escorted out through the army barracks. Several of us swung around an iron fencing which over hung the cliff face. We must have been mad, but it was great fun at the time. Fantastic to watch your You Tube clip.

imagine the sheer amount of work went into these tunnels.

With Dover becoming a garrison town, there was a need for barracks and storerooms for the additional troops and their equipment. The effective solution to this was to create a complex of tunnels about 15 meters below the surface of the famous White Cliffs of Dover... As well as Casemate there are four other Dover Castle tunnels. At the top is Annex, which was dug out in 1941 to use as a military dressing station, where casualties were assessed and treated before being sent to hospitals further inland...At its deepest, the tunnel is 75 metres (246 feet) below the sea level.

Very cool explore! My main fear would be encountering dry drowning in a pocket of methane, in one of those places. I'm amazed at how extensive that tunnel network is. Also amazed at how little water there was, considering the walls are chalk. Thanks for doing this.

The last tunnel (the one before the mosquitoes) looked like a sewer to my engineer's eye. The shape and the slightly sloped channel - the W.C.'s had to drain somewhere...

SpiderAlex climbs again. I love tunnels and bunker explores and was astounded at how long the tunnels ran for. Interesting to see names and dates to see how far back the history goes. Thanks Alex Steve and Ray. Xx

Got to love how they keep it juuust maintained enough to be re-used quickly in an emergency.

I'm surprised experienced explorers, like yourselves, would not have at least one set of spare batteries for your flashlights (torches). Just a suggestion... At any rate, thanks for posting your explorations. As a student of history they are fascinating.

What a brilliant place to explore….thanks for sharing 👍🏻👍🏻

Top explore guys. Thoroughly enjoyed 👍

What a cool explore. Thanks for all you do and much love to you ❤❤

You guys are insane. you broke the cardinal rule for underground exploration. ALWAYS BRING EXTRA BATTERIES FOR ALL YOUR LIGHTS, and also a full power bank for your rechargeable gear and don't forget the cables to connect them to your power bank. Light is the one thing you CANNOT do without! Other than that, you guys did a bang up job, I had no idea that there were tunnels in the Dover cliffs, Also I thought the white cliffs of dover were solid rock, and not chalk! Shows how much I know! I am part of a Flint Knapping community and came across a guy who wanted to do some knapping of rock from the Cliffs of Dover, but neither of us knew it was Chalk! So it would be completely useless for flint knapping! But it would be good for Carving. I have some carving tools used for various stone such as sandstone, soapstone and chalk so I could make something quite nice with a decent slab of it, so I am looking at the rock in the tunnels and thinking, hmmm, I could do some carving of that rock too, it would be nice to have a nice three foot or four foot rectangular slab of that Chalk but I don't think anyone quarries it, do they?

WOW-O-WOW was that a great find and tour. Those tunnels are very extraordinary. It's so wonderful that you explored them. I wonder if anyone has made a 3D representational drawing of the entire system of tunnels. That would be something to see. Thank you all for the great explore. I really enjoyed watching this video.

We didn’t see any light at the end of the tunnel on this one 🤣 Glad we made it out safe though 🤟

That was amazing , those tunnels went on forever . Thanks for sharing that explore , in some places it was very dodgey , with no place to turn around , and full of mosquitoes , that would bring on a panic attack . I'm glad I saw it from this side of the screen . Stuart in Canada ..

Look forward to this. 30 mins to go This was an amazing explore. Well used routes in and out. Much human traffic has used those tunnels. It was a tad spooky in there. Well done guys on another excellent explore and thanks for sharing it with us lot! Take care team. See you next weekend! 🤗💙💙🤗

Oh! Really enjoyed the exploration. The colored bricking was gorgeous. Very pretty. Thx!!! 😘🌷🌷🌷👍🏼👍🏼👍🏼

Awesome explore as always man! Smashing it! Stay safe and well Guys and girls! 👌💪⭐️❤️

Mate, your explores are unreal! Taking this to the next level.

Great explore and video, thanks Alex 😎👍

Brilliant, enjoyed this so much, well done guys and Custard Cream also.

Nice explore!! Made me nervous though. I explore old anthracite coal mines in Pennsylvsnia and I recommend you use a surveyors string and tie it to the beginning. As you go deeper the string will always lead you back(especially if your lights fail) just like firemen follow their hose back out of a building. It's like an automatic maping back to the entrance. Do you have an air meter with you? Just incase the air is stale(low oxygen).Great explore!!

Thank you all, for the explore! Much better without all the steel reinforcements around ya. Safe journeys, and hopefully no more mosquitos! My dad fell off the cliffs when he was 17, that was in 1914, lol.

AWESOME JOB exploring and sharing the adventure !!! Many THANKS

Love these channels. So much abandoned building and bunkers we made and spent millions and just they left to rot. See it all over the world. I watch Exploring the unbeaten path also. Great work guys. And I love the excitement they have. I find fascinating who made that and who worked down there. Be good to find info to try and find who worked there and interview tjem

An awsome adventure from you guys. Top draw as always. Thanks for doing this for our entertainment 10/10

One of the best videos so far! Awesome video guys! 🤟🇦🇺🦘

Brilliant explore x

Thankyou really enjoyed that guys well done ❤

I watch them every Sunday and I look forward to it

Thanks for the tour.

Great explore Alex, someone has spent a lot of time and money building the supports and things. Really interesting to see what looked like a room full of flimsy petrol cans rusting away. Keep up the good work stay safe. 👍

This was so entertaining guys, I loved it. Thanks everyone 😊

Hello 👋🏻 from British Columbia Canada 🇨🇦. I love your channel and the amazing adventures! What an awesome exploration , cheers 🍻 guys ! 🙂 those tunnels are crazy so many of them running all over the place down there. It’s hard to know where to go next and easy to get lost! 😮 I’m only about 10 min in but definitely looking forward to seeing all of this 👍🏻 Anyone have any idea what all the army tins were for ? Maybe fuel oil / liquid white gas cans for lamps / or cooking stovetops etc ?

That was Epic. Thank you for the Adventure . Can't wait for the next one ❤❤❤❤❤

amazing explore , thanks guys and Custard!

Still worth watching once again thx guys

Totally blown away by this video. Never knew about the existence of such an underground bomb shelter in Dover. Thousands could take cover in such an area. Thank you for exploring these tunnels and sharing on UTube. Without your curiosity and bravery I never would have seen it. I’m sure this area was utilized during the horrible bombings of WW II. May they never be necessary again.

I screwed up and watched Exploring Within's video first. I normally wait for yours to watch 1st and watch the others after. I do like watching all the explores because I see different things. I started watching your channel 1st so I like to start with yours 1st. Still catching up with Steve Matt and Ray's libraries because they are all good as well. Thx again guys and a shout out to to Ned and Eddie

Love the dedication guys. Keep it up love watching this stuff !

Amazing , I'd love to explore them, love your channel, rite up my street 👍

Thanks for posting this awesome adventurous video, i enjoyed watching it immensely 🙂

Another great explore boys and girl, great Sunday eve entertainment! Take it easy peeps!

Wot an explore brilliant love it thank you great video

Amazing explore! Love how pristine those labyrinthine tunnels were. There are just SO many tunnels under Dover, and these were brand-new to me too, which is always a treat.

So brilliant watching you exploring caves

"Ray" is the worse kind of explorer to explore with, wants to get everywhere first, do everything first, see everything first, and spoil it for everyone else by telling you what's there.

That was awesome guys loved it 😀👍👍👍👍👍

Oh I am so sorry. I fall asleep, so the premier passed away. Have a good start into the week and cheers to Vacant Haven 👍👍👍

😂😂😂 You said a onsie! I laughed so hard out loud. I love watching y'all. ❤

That was awesome thanks for the tour

WoW I came across your Ch by total accident and the video is of an area I've been too, many years ago !! - When we visited my aunt ! Who lived just up the road .. There are some great areas to explore and visit all within a few mins drive of here. Many great times were spent exploring them..

Just like to say, I've been in some great wartime tunnels in Dover and have enjoyed exploring them. I was searching for this one, but didn't find it. I would have liked to have see this one for sure. I'm sure though, there are many I haven't been in and would like very much if possible, to join you guys on an explore sometime. I used to have a friend from Kent who I used to go with, but unfortunately his work prevents him from going anymore, which means, I go on my own. Not the same. I've seen a couple of you videos and have enjoyed watching them, also, looks like you are a good bunch of guys.

The sloped doors are anti gas doors they had a treated cloth layed against the slope. They could be rolled down from above and were very fast to install. They used them in WW1 bunkers on the western front. The oval tunnels are the sewers

Looking forward to watching the video guy’s.

Thank you that was exciting, scary but well interesting well done all of you ❤

“That is the start of every horror film” how true.

Well done guys I enjoyed that video

Thanks for these great videos

Nice going! I got lost; I don't know how you found your way out. Thanks!

That was crazy amazingly wow to watch . I was feeling clostaphobic just watching you guys go into those tight tunnels. But there is always a beckoning to go and see where it leads to Thankyou ❤

Oh wow, _so_ glad I found your channel… Of course, now I have to binge every video 🥳🎉

Stunning. Imagine finding that when you were kids.

I understand those tunnels are VERY haunted. We've heard about it even in the states.

Amazing and fascinating!!!

Cool explore! Very interesting place Stay safe. All the best from Northern Nevada, USA

I had a lady friend from Scotland, who immigrated to the States after the big war, and she told me that when she was a teenager, she and all the other children who would be playing in the fields below, would all run into the caves (that's what she called them), when the bombs were falling. She told me that there wasn't a minute to lose, and if you tarried, you would die. She told me that one time, that her girlfriend was lagging behind, and my friend, (her nickname was Kitty), said one moment the gal was there, and the next moment she was gone. I can't even imagine how frightening it was to have to run to the caves while bombs were falling, let alone the horror of losing a friend because her little legs couldn't carry her fast enough. 😭 Thank-you for this video. My friend is gone now, she passed from old age, but now I know what the caves look like that she was talking about.

Hidden history!! Good job to all..

Great video!

Nice exploration. When I was younger I explored the tunnels under Ft Armistead in Baltimore harbor. This was in the 1970's. I wouldn't go there now too many weirdos and creepy people hang around there.

Love how you guys speak, its so intriguing. Keep it up boys!

I carnt get back on to the live chat. Still watching thou this is amazing u guys u go above n beyond thank you ❤

That was amazing I would love to go down there myself with you guys to look around the tunnels of Dover. I know some ww2 airfields if you guys are up for coming up to Lincolnshire for a walk about in Lincolnshire there are some old homes around here.

So exciting,felt like I was there

Great ending for October lol Thought you found some wild lair there at first, nice exploration - keep safe!

Thanks for the adventure, you guys are very fun to watch.. I live by carelessly through your journeys..

Great stuff

Awesome explore 🧲⚓️👍

A very nice set of tunnels. Thanks for exploring!

New sub. Love ❤️ yalls energy

Wow… what an amazing little adventure 👌

I really enjoyed it. ❤❤ Great piece of adventure 😁 well done all of you ❤❤

This looks great. Can’t wait to see the gang doin their thing!

First explore ive seen of Hellfire Corner! Brilliant.❤

Hey from tx USA thanks for the tour guys. God bless 🙌 🙏🏻✝️

That was an epic adventure. Im from the US and the first video I’ve seen. Hooked! Liked, shared, subscribed, and commented. I had no idea of the term mozzies. We call them skeaters for short. I hate them. I’m really allergic to the ones in my state. I’ve been bit by some, I could feel in Alaska. They were huge! I wasn’t allergic to them so the bit did not swell up or itch insanely bad. Great find. Ready for more adventures and watching old videos.

Amazing. Thank you for the video. It doesn’t look very ancient. Unlike many other secret underground tunnels everywhere in the world.

Very nice to see Alex, in his natural habitat exploring chalk tunnels and being The Mole-Spiderman.😉 Interesting and enjoyable video nice length too. You are all so brave to be there in semi darkness. Thank you for the fun tag along 💖💖 Flowers for Custard Cream 💐💐

Loved the last bit! Well the sewer is nice and clean now!
