About Tenby Adventure
Tenby Adventure is a licensed outdoor activity provider operating from Tenby Harbour, Pembrokeshire and running guided coasteering, sea kayaking, and rock climbing across the South Pembrokeshire coast. Founded in 2017, we’ve safely guided over 30,000 participants and are the only provider running coasteering sessions within Tenby itself. Our guides hold the highest UK qualifications and carry state-of-the-art satellite locator beacons. We’re licensed by the Adventure Activities Licensing Authority, members of the National Coasteering Charter, listed by VisitWales, and rated #1 for activities in Tenby on TripAdvisor. We operate exclusively in South Pembrokeshire – including Tenby, Lydstep, Stackpole, and Manorbier – from an off-grid, solar-powered base.
We’re Pembrokeshire-based coasteerers, kayakers, climbers, surfers, scientists, free-divers, eaters of cake, investigators of weird caves, friends of crabs and seals, owners of many carabiners. We’re proud members of the Pembrokeshire Adventure collective, and passionate about the coast we work on.
Since we began we’ve supported Pembrokeshire’s Marine Code and the Pembrokeshire Coasteering Concordat, and worked alongside ecologists, marine biologists, the Pembrokeshire Coast National Park and the National Trust to leave every place we work better than we found it.
That runs through everything we do. Our Ghosteering project recovers lost ‘ghost’ fishing gear from the coast, which we deliver to Odyssey Innovation in Milford Haven to be recycled into kayaks! Our office runs entirely off-grid on a Victron solar system – 7.1 megawatt-hours of clean energy generated since install, powering kit drying, admin, coffee, and very soon charging our electric van straight from the sun (the widget shows what we’re producing right now). We even insulate the building with worn-out wetsuits too far gone to repair.
We’re lucky to do non-standard stuff in special places – sometimes challenging, never run-of-the-mill. The people who seek us out aren’t run-of-the-mill either. They’re our kind of people, and a reason to find the next adventure

Mark
Benevolent Dictator
Mark began adventuring aged 8, when he completed a semi-accidental solo crossing of Carmarthen Bay on a catamaran made out of scaffolding and optimism. Next came a solo ascent of Yr Wyddfa (Snowdon) aged 10 (his mum thought he’d gone to the Butlins arcade). He made several attempts on the land-yacht speed record from the age of 12, ending in an unfortunate incident on Pendine Sands that could’ve been much, much worse… A successful-ish home-made hang-glider flight aged 13 lead to a more successful glider pilot’s license aged 16.
Since then Mark has surfed all over the world, climbed many Alps, free-dived on shipwrecks in the Caribbean, sailed across the Atlantic on a boat he built in a potato shed and learnt to fly paragliders across the Welsh coast and mountains. He now lives in a passive house he built in the woods near Tenby.
Mark has been instructing all kinds of outdoor pursuits, from climbing to archery to surfing and coasteering, since 2007. Early on he realised that not only is coasteering pretty much the best of them all, but Pembrokeshire is probably the best place in the world to do it.
Tom
Head of Training, Vintner
Tom likes kayaks. A lot. He first sat in one aged 6 and despite the sanitary practicalities, didn’t get out ’til he was well into his teens. During that time he represented Wales in kayak polo and paddled/fell down many of the biggest waterfalls in Wales. He still sleeps in a ‘yak but now also operates on land and has climbed all over the world from the Caucasus Mountains to the slopes of Mont Blanc. Tom is the proprietor of the only vineyard in Sageston.
Tom now leads expeditions all over the world and is the holder of the almost mythical 5 Star kayak award as well as a wealth of qualifications in pretty much all of the outdoor pursuits. Tom is a wild sea-food expert and you’re likely to find yourself munching on some unexpectedly tasty seaweed on one of his coasteers.
When not adventuring, Tom likes to hide in his workshop and build hand-made paddles from locally-sourced windfall timber.
Myrdd
Guide, Gumpian cyclist
Myrdd (pronounced ‘merv’) brings a flavour of calm to coasteering sessions, because of his accent – he’s from the west coast of Ireland, so sounds all mellow and reassuring. It’s deceptive because Myrdd is nearly always bouncing of the walls with almost disturbing levels of enthusiasm.
Myrdd is a rabid cyclist. Not for him a quick spin down the shops, no – Myrdd cycles a LONG way when he pops out for a ride. In 2019 he hopped on his bike, set off down the road and came back 15,000km later having toured across Europe.
Charles
Guide, cape-wearer, 2015 New Zealand Sand-castle champion
Charles is an experienced coasteering guide, accomplished climber and legendary route-setter.
He’s the creator of the world-famous Spotify playlist ‘What is Techno? And Why?’ and a toe model for absolutely no-one. Charles lives in a yurt near a remote waterfall in which he takes daily dawn-swims and drives a Passat that in the event of any kind of apocalypse has enough stuff in it to rebuild civilisation.
Meg
COASTEERING GUIDE, Neuroscientist, Frisbee Champion
Meg grew up in Pembrokeshire and after spending a while abroad learning to surf and perfecting the art of hanging around at the beach, came back to the UK to study Neuroscience. Meg is a quietly calming presence in the water and having joined us during the ridiculously rough 2024 summer season is now an expert in keeping people safe on choppier days.
Meg really likes Hermit Crabs, is a legendarily skilled frisbee pilot and can not operate our wetsuit hanging device.
Henry
Rock Maestro
When he’s not guiding people for his business Climb Pembroke on cliffs and mountains all over the UK, Henry likes to relax by climbing the cliffs and mountains of the UK. He’s equally at home running a beginner session on a mellow Pembrokeshire sea-cliff as he is persuading clients up vertical ice-bound gulleys in the Scottish Highlands.
A climbing instructor with almost 20 years of experience and holder of the WMCI, Henry REALLY likes climbing.
Rich
Guide, 90s throwback, occasional nude-surfer
An absolute coasteering fanatic, Rich is the inventor of the Twisted Penguin jump and is a veteran of many, many coasteers. Outside of coasteering season Rich is a farmer.
Rich tries to surf every single day (even if the surf is rubbish) and can often be found out back at Manorbier on winter days with his signature Mississippi Mud Flap (mullet) blowing in the howling onshore wind.
Rich likes planes and sports a selection of aviation-themed tattoos.
Rachel
Coasteering Guide, Philosopher, Brother to Alpaca
Rachel is an experienced assistant guide and the second member of the Alpaca family to joint Tenby Adventure. Like her brother before her, Rach has reliable calm in the face of gnarliness – a valuable trait in a guide. Rachel is a 3rd year Philosophy student and can often be seen staring off across the rolling hills of deep thought. We’d see her brother Zac staring into the distance too, but he was probably just thinking about surfboards, or protein.
Ricky
Watersports Instructor, Castaway, Master of Lunch
Ricky is a water sports instructor with over a decade of experience. His destiny became clear when – aged 7 – he was banned from a campsite for taking his commitment to piracy more seriously than perhaps he should.
After myriad multi-day hikes through Scottish mountains in the dead of winter, a shipwreck (kayak-wreck?) on an uninhabited Croatian outcrop and very many other odd adventures Ricky has developed according to his CV) ‘a clam and joy-embracing style that puts people at their ease’. Maybe lock up your bi-valves…
He is also an expert at lunch. Like seriously, no sad midday sarnie for this chap, it’s real food all the way!
Sam
Kayak Guide, Coastal Troglodyte
Sam inhabits a cave (former fisherman’s shed) overlooking Tenby harbour. He shares the cave with his kayak – and so has some things in common with his kayak-mentor Tom (who also cohabited with his boat for many years until he learnt the art of punching way above his weight and met Sarah).
Sam is on his way to study music, sings bass in several choirs and his favourite piece of music is St John Passion
Along with the above, we have a squad of eager lead and assistant guides who help us keep you safe. All are finely tuned adventure machines, highly qualified and trained to our particular ways. They’re ready to feed you some seaweed, gently encourage you to jump off something, climb a thing, embark on a voyage, make friends with a jellyfish or give you a tow.
