What is Coasteering?

Coasteering on Anglesey is a thrilling mix of wild swimming, rock climbing and cliff jumping. A truly adrenaline fuelled action packed coastal adventure. Guaranteed to make lasting memories and an unbeatable way to expend excess energy and keep fit. Amazing fun for both adults and children.

  • Qualified and experienced instructors

What is your Coasteering session like?

Your Anglesey Coasteering adventure usually begins after our initial meet at the picturesque Trearddur bay. We then drive on to the most suitable coasteering venue that will provide the best conditions for the day. You will then kit up in warm winter wetsuits, buoyancy aids and helmets. A full safety briefing follows.

Your amazing Coasteering adventure then begins. You will be broken in gently with some easy scrambling over rocks and fun small jumps.

The coasteering fun and adrenaline then ramps up a notch. Bigger jumps and bigger swims. You will find yourself clinging to seemingly blank rock faces up to 20ft above the crystal clear Irish sea. One slip and you’re in the drink! If you don’t fancy being spiderman, don’t worry you can always swim around! That’s the beauty of Coasteering on Anglesey, the challenges are all optional.

Are you afraid of the dark? If the tide is ok you may find yourself in one of the marvelous Anglesey seacaves. Bright sunshine gives way to pitch black at the back of some of these awesome caves. Are you brave enough to go all the way in?

The cliffs of Anglesey are perfect for Coasteering. Never too high they will provide you with numerous jumps to conquer, some up to 10m+. The remarkably complex coastline provides a vast adventure playground. You may only travel 400m on your Coasteering adventure but the fun and excitement is packed in to this phenomenal stretch of Anglesey coastline.

If there is swell then the fun powers up a notch. Timing is crucial if you want to avoid a rinse cycle! In any swell the swims are better than any artificial wave pool.

For the finale of our Anglesey coasteering sessions we always aim to finish on a high. Literally, we save the best till last. Depending on tide height this could mean you have the option of a 10m+ leap of faith. Try to calm your nerves as you climb up to the small overhanging ledge 10m above the azur blue sea. Stand on the edge take a deep breath and take a single step. You have done it, freefall for a second and then land in the deep refreshing sea below. The sense of achievement and satisfaction will stay and the memories will last a lifetime.

Your Coasteering adventure is over, get changed, relax and look forward to a cool drink and a well earnt hearty meal. Coasteering on Anglesey ticked. What’s next?

Who is Coasteering on Anglesey suitable for?

Coasteering on Anglesey is suitable for most people. You do not have to especially fit. If you are finding the climbing too stressful you can simply drop into the sea and swim! Coasteering is ideal for adults and children absolutely love it. Your child just has to be able to cope walking over rough terrain. This usually means 8-9yrs +.

The beauty of coasteering is that we can tailor the venue or the session to suit you or your group and also “challenge by choice”.

Coasteering on Anglesey is a popular choice for Stag and Hen parties making great stories for the wedding day.

Also a great choice for military adventurous training groups involving lots of teamwork and stretching of comfort zones.


I am scared of heights, is Coasteering suitable for me?

Don’t worry if you don’t like the jumps you can simply swim around. You may also surprise yourself. With a bit of coaching, positive self-talk and progressive jumps you might be amazed at what you can achieve. If you don’t try you will never know!!

I am a non-swimmer can I go coasteering?

The ability to swim well isn’t an absolute necessity. You will be wearing a full winter wetsuit made of neoprene. Neoprene is extremely buoyant and this alone should make you float. We also always wear a well fitting buoyancy aid. This will ensure you do not sink.

All you have to do is kick your legs and doggy paddle. We can even use a rope to pull you across any longer swims.

  • Warm Winter wetsuit
