Zip World Caverns: Experience Adventure

Zip World Caverns – A truly exhilarating experience, that’ll leave anyone who takes on the greatest underground adventure utterly terrified.

Earlier in the year we had previously taken on ‘Bounce Below‘ which is just one of the unique adventures Zip World offers, but that is a walk in the park compared to this monster challenge we were back for. Two years in the making, Zip World Caverns is a remarkable, uniquely exhilarating adventure found deep inside a former slate mine, that has been inaccessible for nearly 200 years. Failing to disappoint, they have managed to create one of the world’s largest underground zipline adventures! Anyone in average fitness should be able to complete the course. It may look physically demanding, but it’s mostly tough psychologically!

Zip World Caverns: An exhilarating underground adventure


Before you are let loose in the caverns, you must be able to complete the two training sessions. After being kitted out in some of the world’s safest harnesses and CLic-iTs tools, have no worries should you lose your footing whilst climbing around the edge of a 100ft+ cavern wall. Thanks to the patented design, there is no way you can accidentally detach both safety clips at the same time.

Zip line training consists of getting to grips using the CLic-iT hooks along the wire and the ‘Zippy Trolley’ for ziplines. Safe to say, you will treat these tools like they are your best friend as they are ultimately keeping you from having an unhappy end to your adventure.

Once the outdoor training session is complete, it’s time to head underground. The sudden shock of realism will hit you hard as you walk past the 100ft+ caverns to the second training area. The nerves will soon kick in as you complete the next round of training in preparation to be left to your own devices to navigate your way around the 2-3 hour thrill seeking adventure.

Zip World Caverns Experience

It’s time. Whether you are feeling pretty confident or utterly terrified, the underground world of ziplines, cavern wall climbs and decents down ladders await!

Once you make the first zip line across from the start, it’s all up to you as the course puts your heart rate through its paces. No matter how much you don’t want to look down, you can’t help but take a glance – usually followed by some wobbly knees as you realise just what you are taking on!

The atmosphere inside is great, although a little chilly, Zip World have kept things real by leaving the rock walls as untouched as possible. With technicoloured lighting all around the caverns, providing you just enough light as you fly past rock walls at just out of arms reach, along one of the 15 ziplines featured. Whilst some of the ziplines aren’t insanely fast, it’s more about testing you psychologically as you fly over huge drops, eagerly wanting to land back onto the platform the other side.

If that isn’t enough, did I mention that in between the ziplines you will find yourself facing multiple mental challenges along the way? You will have to pass a wobbly bridge that rocks with every footstep, climb your way up by stepping on a series of metal plates that are pinned to the rock edge, that are only big enough for tiny feet. Not forgetting side stepping across wooden logs, suspended above a drop into darkness.


Nothing quite like says ‘Don’t look down’ by mentally shouting it to yourself for 2-3 hours. You will need to make sure you’re hooked to the right cable, feet in the right places to not slip, crawl through narrow tunnel like passages to make your way round the course.

Zip World really do like to keep things dramatic, with an end that everyone brave enough will remember. Those who don’t heights, will really be staring into the eyes of fear if you opt to take the extension course. As you clip your way around the TOP of the cavern you will need to make your way across.. either hanging along monkey bars, or take the terrifying tightrope. Both of us opted for the tight rope, and made it safely over the 100ft+ drop and continued upward via ferrata to finish with a fast speed zipline.

As terrifying as it was, it was one of my best birthday’s to date. We both felt like we had really accomplished something after some testing moments and leaps of faith. Zip World Caverns is a must for all looking to put themselves through their paces.

The experience lasts around 3 hours in total depending how fast you are. Being underground, Zip World Caverns are open all year round which means there’s no excuse the next time you find yourself in Wales.

      You’ll love it! Mentally challenging forcing yourself to trust a few hooks and a wire to take you safely across 100ft drops into darkness. It’s going to be hard to top this!

    Oh my word my claustrophobia kicks into high gear at the thought of going underground but to add in a zipline – I do admire your courage though and the pictures are amazing. We have a tiny zipline in London Ontario and I couldn’t even go on that it was too scarey…lo…

    Pics you posted gives an impression of a really adventureous experience. As you rightly said normal zip line is a walk in the park when you look at this. Nice information.Bookmarked.

    What fun! We have had some zip line experiences and they were really an amazing experience. oNce in Canada and another in Tortola…Both times my husband was working so I ‘had’ to go outside my comfort zone and go with the kids. It turned out to be fantastic and not nearly as scary as I feared. It was also a great chance for me to show the kids that you can face your fears and live life to the fullest. 🙂

    Not being able to see far and wide like you do in typical tree top zip line experiences would make this a really different experience! Would love to try this out!

      Glad you pushed yourself to go outside of your comfort zone Natalie. It’s amazing what you can achieve once you put your mind to it 🙂 We certainly faced our fears here, you really would love the experience

    OMW this looks amazing!

    I thought I’d mention that we have the most amazing zip line adventures in South Africa. My favorite is one in Mpumalanga, which is about 3 hours drive from Joburg.

    It’s all across and in between the tree tops of one of the most breathtaking places in our county. There are also cavern zip line adventures but thought since you’ve already done that why not try a different one!

    We also have something called kloofing. in the same area. basically it’s an adventure where you jump off waterfalls, clear gorges by jumping and jump from cliffs into pools. Needless to say, the ADRENALINE never stops pumping!

    Maybe a trip you should add to your bucket List!
