Discover the impressive coastline of North Wales from an entirely new perspective and join us on an exhilarating sea-level traverse.

A real test of nerve, this activity involves scrambling across the rocks to reach the dramatic sea cliffs where, attached to ropes, you’ll climb the steepest sections. To reach the next cliff, you’ll need to harness yourself to a rope bridge and slide yourself over the waves below.

This activity is both a physical challenge and a thrill, and is sure to leave you and your teammates with a true feeling of accomplishment.

Possibly.... Whilst SLT is a dry activity, there is always a chance of being splashed as you'll be near the sea, and every now and then a wave might get your feet. But it's certainly not a submersion activity.


Most people are fine sea level traversing, there may be an element of height on some sections (though you will be on ropes for safety), and you need to use some technical gear that we will guide you through (it’s very similar to what you might have used on a ropes course) If you’re happy to scramble about on rocky ground and climb trees, then this will be for you.


We provide the essential safety items you’ll need, such as a harness, helmet and buoyancy aid, and we can kit you up with some waterproofs if you don't have your own (only for windy or wet days)

You would need to bring:
  • Warm clothing, ideally that dries quickly (meaning jeans are not ideal at all).
  • Waterproofs to cover you up, this isn't always necessary at all but on a wet or windy day these will keep you comfortable (we do have some we can lend you if needed)
  • Shoes. There is a good chance these will get wet. They need to be stiff soled so you can stand on pointy rock, and have secure fastenings to stop them coming off!Stiff soles are really important as the sea cliffs are knobbly and you don’t want to feel all the knobbles through the sole of your shoe, so it needs to be robust. Jelly shoes, pumps, wetsuit boots and other floppy shoes are not suitable at all. Astroturf shoes are really slippery on wet rock so avoid them too. Your best bet is a good robust trainer shoe.
  • Spare clothes for afterwards just incase you do end up getting quite wet. Especially shoes.
  • Sun cream and any medication you would usually carry.
  • People with long hair bring something to tie your hair back (that will fit under a helmet!)
  • Suncream, for when it’s nice and sunny! Which is surprisingly often on Anglesey!
  • Any medication you might usually carry or need.


Because we are so close to the seaside we run half day sessions, and because travel time is so short this still gives plenty of time to make the most of the activity. We can do full day sessions too for the hardened explorers amongst you (you’d need to bring food and drink for a full day, or get a packed lunch from us).


The best place for this locally is a 5 min drive away. Sometimes if the conditions are not right for it, we may travel a little further, but never more than 25 mins to go to a suitable spot.


Sea Level Traversing is not really suitable for people under the age of 11, but it is still possible at certain locations which are really easy going. We use a variety of locations to suit varying abilities so can accommodate pretty much everyone.

We work with groups of 8. If we go over this, we can get a second instructor.


SLT is a great year/round activity, because in the winter, we can keep it fairly dry if we want to.

We have excellent local venues for sea level traversing. And our instructors have a good working knowledge of the venues, so they can set up all sorts of interesting challenges along the way.

Like all adventure activities, there is an element of risk, otherwise it would be known as 'boring activities'...
