Coasteering is one of the most exhilarating ways to explore a coastline, combining rock climbing, swimming, scrambling and jumping all within a few metres of sea level.[4] Born in Pembrokeshire during the early 1980s when local surfers began exploring the cliffs between sessions, this unique activity has evolved from a niche pursuit into a world-class adventure suitable for families, beginners and thrill-seekers alike.[5] Today, Pembrokeshire remains the coasteering heartland of Wales, offering some of the best routes in the world with dramatic cliffs, hidden caves, sheltered coves and abundant marine wildlife.[5]
What Exactly Is Coasteering?
Coasteering is fundamentally about exploring the coastline at sea level in ways that would be impossible from land alone.[4] Rather than following a single path, you'll navigate around rocky outcrops, through sea caves and across wave-cut platforms, combining multiple skills as you go. The activity typically involves scrambling over boulders, swimming between sections of coast, climbing short rock faces and, if you choose, jumping from rocks into deeper water.[4] What makes coasteering special is its adaptability—sessions can be as mellow and exploratory or as adventurous and adrenaline-fuelled as you wish, depending on your comfort level and experience.[3]
Beyond the physical challenge, coasteering offers genuine education about the marine environment. You'll learn about local flora and fauna, observe wildlife such as spider crabs, sponges and seaweeds, and occasionally encounter seals or porpoises.[1][3] Guided sessions also teach you about coastal characteristics, tidal patterns and the geology that shapes these remarkable landscapes.
Pembrokeshire: The Birthplace of Coasteering
Pembrokeshire's claim as the official birthplace of coasteering is well-earned.[1] The region's spectacular coastline provides the ideal setting for this activity, with vertical cliffs dropping straight into the sea, sheltered coves, sea caves and a huge variety of locations to explore.[4] The most famous coasteering areas are found on the St Davids Peninsula and the South Pembrokeshire Coast, with iconic spots including Abereiddy and the Blue Lagoon near Tyddewi.[5]
Since TYF Adventure introduced coasteering to the world in 1986, expert guides have taken over 200,000 people out onto the rugged coastline of St Davids.[2] This pioneering heritage means Pembrokeshire operators have unmatched knowledge of local conditions, hidden features and safe practices. The combination of stunning natural beauty, reliable coastal conditions and expert local guides makes Pembrokeshire the gold standard for coasteering experiences.
What a Typical Coasteering Session Involves
Most coasteering sessions last between 2.5 and 4 hours, depending on the operator and difficulty level chosen.[1][2] You'll typically arrive 10 minutes early to be fitted with specialist equipment: a wetsuit, helmet and buoyancy aid, all provided by your guide.[2][3] All you need to bring are old trainers or secure beach shoes with decent soles, a towel and swimmers if you prefer to wear them under the wetsuit.[3][6]
Once kitted up, your guide will lead you along the coastline, choosing a route suited to group conditions and your experience level. You'll scramble over rocks, wade through shallow water and swim through deeper sections, discovering features such as sea caves, swirling whirlpools, dramatic sluices and rocky gullies.[7] Cliff jumps are always optional—you're in complete control of your adventure. The buoyancy aid does most of the work in the water, so even if you're not a strong swimmer, you can relax and enjoy the experience.[7] Throughout the session, your guide will share knowledge about the environment and ensure your safety at every stage.
Best Operators and Session Types
Pembrokeshire has several excellent coasteering operators, each offering different experiences tailored to your needs. TYF Adventure in St Davids offers Discovery sessions ideal for first-timers, where you can scramble, leap, swim and explore at your own pace under expert supervision.[2] They also run Explorer sessions for those seeking a faster pace and more challenging scrambles, plus specialist powerboat coasteering trips that reach remote spots only accessible by water.[2]
Tenby Adventure operates at three superb South Pembrokeshire locations: Lydstep Headland (known for sea caves and cliff jumps), Tenby's St Catherine's Island (offering mellow tidal cruises) and Stackpole Quay (perfect for accessible, relaxed exploration).[3] They recommend the best location based on conditions and your group's experience level. Prices typically start from £45 per person, with sessions lasting around 2.5 to 3 hours.[3]
Is Coasteering Suitable for Beginners?
Absolutely. Coasteering is designed to be accessible to people of all ages and abilities, provided you can swim.[3] Most operators welcome ages 8 and upwards, with children under 16 requiring adult supervision.[2] Sessions are tailored to suit your group, meaning beginners work at a comfortable pace with no pressure to attempt features you're not ready for.[3] Your guide will assess conditions and adjust the route accordingly, ensuring you gain confidence gradually.
Safety is paramount in coasteering. Proper equipment—wetsuits, helmets and buoyancy aids—protects you from cold water and minor bumps.[2][3] More importantly, detailed knowledge of sea conditions, tides, weather patterns and first aid are essential, which is why choosing a reputable local operator is crucial.[4] A sudden change in weather or swell can transform conditions quickly, so guides trained in the environment are invaluable.
Preparing for Your First Session
Before booking, confirm you're a reasonably confident swimmer—buoyancy aids help enormously, but swimming ability is the main requirement.[2][3] Wear old trainers or secure beach shoes; flip-flops and sandals won't stay on.[3] Bring a towel and consider packing swimmers to wear over your wetsuit if you prefer. Most operators provide changing facilities and lockers for your belongings.[2]
Check the operator's minimum age requirements and any specific fitness or health considerations. If you have concerns, contact the operator beforehand—they're experienced in working with people of varying abilities and can advise whether coasteering is right for you. Arrive early on the day so guides have time to fit you properly with equipment and brief you on safety procedures.
