Dive into the dark world of deep caverns that lie under the surface. There are hundreds of thousands of miles of underground passageways beneath Wales, all waiting for you to explore.
We have a range of trips for all abilities and styles, from big open passage ways to tight mud crawls, climbing/ abseiling on rock faces to paddling over underground lagoons.
Explore the slate caverns and tunnels that put Wales on the map.
Climb, abseil and traverse along chambers following the old quarrymen’s footsteps.
All the challenges are optional which makes this the perfect activity for a family adventure, or a mixed ability group (Hen/ Stag Do).

These are classic trips, popular with school residentials and holiday goers alike.
Located in between Betws y Coed and Blaenau Ffestiniog, we have several trip options available, which allows us to offer activities for returning visitors as well as new explorers. If you have been before or have a preference, please let us know in your booking (additional information).
You can combine this trip with any of our other half day options for an extended day (Gorge Walking, Canyoning, Mountain Biking, Coasteering etc).
Dirtier, wetter, smaller. Unlike the vast chambers in the slate mines, these trips are more akin to British caving/ potholing.
These trips start at the top and descend down through the mine via a series of abseils and traverses.
Fun trips for those who have been abseiling before.

Big abseils to get the heart rate going. Be prepared to get wet and dirty as you explore these underground passageways. Most of the passageways are a comfortable height whilst stopes/ chambers are long and narrow. Expect to use a via ferrata style system to traverse over the different levels and explore parts of this mine.
This is located between Beddgellert and Porthmadog this is a good activity to combine with Canyoning, Rock Climbing and Mountain Biking for an extended day.
Hidden near Mold, Flintshire, these muddy holes are full of crawling, with some tight-ish squeezes.
Exciting trip for those looking to try out some real caving for the first time.
There is a second cave on the other side of the river to explore if you’ve still got the energy.

Enjoyed by adults and children alike, this is an experience you’ll never forget.
Whilst a degree of confidence is required for all the small and tight-ish passageways, these trips are accessible for complete beginners and provides the only real caving experience in North Wales.
We also run easier and harder caving trips in Yorkshire, Peak District and South Wales, get in touch if you wish to try these out.
Given the location of this activity, it is not possible to combine this activity with any other activities in a single day, however we guarantee you’ll be ready for a well deserved pub lunch and nice cold beer or coca cola afterwards.

Regardless of whether you add this option we always aim to take photos on all our trips to send you following the activity.
- keyboard_arrow_downkeyboard_arrow_upHire a Luxury Changing Robe
Struggling using a normal towel to cover up whilst getting changed?
Our Luxury Changing Robes solve this problem, wearing one like a poncho makes changing so much easier. This isn’t essential, but these items have become increasingly popular in the last couple of years for a good reason. Like almost all providers we get changed and ready for the activity near to where the activity starts, and changed again near our vehicles after the activity.
We’ve chosen thick microfibre robes that are very cosy, to help keep you warm and dry you faster after adventures. These are usually made up of a 80% Polyester - 20% Polyamide mix, which is super absorbent and quick drying. Machine washable at 30 degrees.
Both sizes of robes are an XL width (85-95cm) which gives most people the ability to get changed easily and comfortably inside.
Our Medium Robe is 108cm in length and designed for people upto the height of 5ft 11inches/ 180cm. Our Tall is 118cm in length and designed for those over the height of 5ft 10inches/ 175cm. Sadly we don’t offer smaller sizes for children yet, but they are more than welcome to hire a Medium robe.
- £5 to hire Luxury Changing Robe sizes Medium/Tall
- £30 to hire and keep new Luxury Changing Robe siize Medium
- £35 to hire and keep new Luxury Changing Robe size Tall
Colours available: Black/Blue/Red
- keyboard_arrow_downkeyboard_arrow_upLunches and Drinks
On all full day/ extended day bookings it is essential that you bring lunch and a drink with you. For full day single activities we recommend light lunches with big breakfasts and evening meals either side of the day's activity.
You don’t want to be caught out on an energy low, but neither do you want a very filling meal requiring a long digesting time. For multi-activities you may want a slightly longer lunch break between the two activities where you can feast and digest it before starting the next one.
A hot drink in a flask is also recommended for all but the warmest days, we can provide this if requested, with hot squash, chocolate, tea, coffee.
- keyboard_arrow_downkeyboard_arrow_upWeather
Our underground adventures are generally a great option in poor weather, being underground and can be run in all but the most extreme weather (excluding the caves). However you will be exposed to the elements on the way to and from the mine.
In the extreme weather events unfortunately we may have to change activity, rearrange the date, or to cancel the activity and receive a full refund. We apologise for any inconvenience this may cause, unfortunately we are at the mercy of the weather Gods.
If we can’t run one of our underground adventures, the only likely option to change activities would be indoor climbing. Fortunately this is a very rare occurrence.
- keyboard_arrow_downkeyboard_arrow_upSafety information
Your safety is our number one priority and all our instructors are highly experienced and qualified to be able to offer these high quality adventures. They have all worked with lots of different clients from all age groups and abilities, and have been assessed by a number of different technical experts over the years.
Despite this, there is an element of risk to all the activities we do, these are adventure activities after all. For example; our instructors won’t be able to stop you falling over and bashing your knee or other parts of your body. They will, however, teach you how to move in these environments, what to look out for and keep safe near the big drops and wild water.
- keyboard_arrow_downkeyboard_arrow_upRecent injuries/ medical conditions
We would advise anyone unsure whether they can/ should join any of these activities to first check it with your GP, or any relevant health specialist. At any point, you are more than welcome to get in touch about any recent injuries or medical conditions you have to discuss how they might impact the activity.
Before each activity we’ll ask everyone to let us know if they have any recent injuries or medical conditions. It is essential you let our instructor know so should something happen, they’ll be prepared to deal with it quickly and effectively. A quiet 1-1 word would be perfect.
We’d like to be able to include everyone in activities, however it is essential that you can wear our safety equipment comfortably and you are aware of any additional risks the activity may propose. If you broke your ankle 2 weeks ago, then sadly it's probably best if you waited a little longer for it to heal before going on one of our activities.
