Snapshot
- Coasteering is a guided coastal adventure sport combining wild swimming, rock scrambling and cliff jumping.
- Coasteering routes stay in the intertidal zone, reaching sea caves and arches no boat can enter.
- Cliff jumping is optional, so first-timers can stick to short swims and easy scrambling.
- The UK has more coasteering providers than the rest of the world combined, with Cornwall and Pembrokeshire leading.
- Warmer options include Portugal's Algarve, Spain's islands and the Mediterranean; the Americas have one operator, in Trinidad and Tobago.
Water has a way of settling people. Blue mind, the science calls it. Coasteering takes that same calm and gives it a pulse. Matt George of Kernow Coasteering answers all your burning questions about this adrenaline-filled adventure.
Standing on a ledge about ten meters (approx. 33 feet) above the Atlantic Ocean, I am enjoying the rhythm of the sea as it gently rolls back and forth. I scrambled up to this point from sea level after I explored a gigantic sea cave.
With my small group of adventurers, we will jump from this precipice back into the ocean and continue our journey along the jagged coastline. If this sounds crazy, maybe you haven’t heard of coasteering?!
What Is Coasteering?
Coasteering includes wild swimming and scrambling over rocks. Call it the art of wrangling a rocky coastline by whatever means, having as much fun as possible. Cliff jumping is the part most people know it for. Indeed, for thrill-seekers, no coasteering session is complete without some tasty cliff jumps to get the adrenaline flowing.
But if jumping from high ledges into water isn’t your bag, don’t worry, there are still plenty of reasons to give coasteering a go. In fact, the flexibility of coasteering is one of the things that has given rise to its popularity. Adrenaline junkies definitely won’t leave disappointed. But for some, simply getting wet and navigating a short distance through the coastal environment can be just as rewarding.
For me, coasteering is first and foremost a form of exploration I haven’t found anywhere else. We primarily travel through the “intertidal zone,” which is the area between high and low tide. All the fun happens in that narrow band of wet rock and shallow water. Coasteering gives us a backstage pass to sea caves, rock arches and other formations that sometimes defy description.
Closer Than a Boat Gets
Of course, ever since humans have taken to the sea, we’ve had a fascination with the coast, and for many, we feel a deep connection to the ocean. I say there is no better way to exercise this connection than coasteering.
And there is no other water activity so hands-on. Almost every step of the way, you’re connected to the environment, literally. You’re either walking or scrambling along the rocks, or pawing your way along them in the water.
Coasteering is about as tactile as adventure gets. Unhindered by any craft, we venture into locations that are completely unreachable any other way. Whether it’s a narrow sea cave entrance, a diminutive sea arch or the spaces in and under wave-smoothed boulders, my explorations have taken me to innumerable places where I’m pretty confident I’m the only human to have ever set foot.
History of Coasteering
Coasteering was coined by British rock climbers, first turning up in print in a seventies sea-cliff climbing guidebook. Taking the suffix from “mountaineering” and adding it to “coast,” the word was born. Yet, these early pioneers of coasteering carried out the activity in a very different fashion from coasteering as we know it today.
Early coasteering was essentially a form of rock climbing. Climbers soon realized they could undertake long adventures — reminiscent of massive mountaineering objectives— by traversing long sections of the coast. Using ropes and full climbing equipment, they aimed to climb sideways, usually well above the water. Swimming served as a last resort, reserved only for obstacles that proved impossible to climb past.
This is in direct contrast to what coasteering is nowadays, when we intend to be in the water most of the time. As wetsuits became widely available from the 1960s onwards, water activities in colder climes suddenly proliferated. Within several years, activities like surfing and sea kayaking were firmly established.
Occasionally, leaving their kayaks or climbing gear behind and donning a wetsuit and a pair of shoes, inquiring minds would start exploring the coast. These people didn’t know it, but they were coasteering.
Today’s Sport
The mid-1980s changed that. An outdoor center in Pembrokeshire, Wales, started offering something new. Coasteering was now a guided activity. Here was a place where first-timers could suddenly have an adventure getting to know the coast up close and having a huge amount of fun at the same time.
Fast forward, and there aren’t many sections of suitable coasteering in the UK where guided coasteering isn’t available. Coasteering began popping up across Europe after the turn of the millennium, with Spain and Portugal the main epicenters in Europe today.
Outside of Europe, coasteering can be hard to find. However, isolated outposts spread the word in Africa, Asia and Oceania. The Americas came late and remain almost untouched.
What You’ll Learn
Like anything worth doing, the main reason is simple. Coasteering is FUN! But let’s dive a little deeper. Why is coasteering so much fun, and what added benefits does it offer?
Coasteering is an undeniably physical activity. It’s my idea of a legit workout. One where you’re so absorbed in what you’re doing and where you are that you don’t think you’re working out. Rest assured, after a few hours of intense swimming, scrambling and jumping, you will feel it when you’re done.
Coasteering is a mental workout, too. Facing and overcoming the emotional challenges thrown at you has manifold benefits. Whether facing your fears to take on the next jump, navigating a dark sea cave or confronting an ocean swell, conquering these challenges feels like a small victory every time.
It’s also a great opportunity for teamwork. Coasteering throws your group together in a way few activities do. You can’t beat the camaraderie from sharing the euphoria (or is that mild terror?) of a good coasteering session.
As I said before, my favorite thing about coasteering is the feeling of exploration. And I can’t think of many activities where you are more immersed in the environment. This results in a much deeper appreciation of the landscape you are exploring. You can’t help but marvel at nature’s infinite beauty and complexity along the coastline you are traveling.
Where Can You Try Coasteering?
Hopefully, you are now convinced you need coasteering in your life. With its origins in the UK, the motherland of coasteering still has more providers than the rest of the world combined. If you head to any part of the UK with a rocky coastline, there’s a good chance coasteering is available.
Coming from Cornwall, my first recommendation is undoubtedly Cornwall. With more than 400 miles of coastline, the hard part is picking a stretch. Also, let’s not forget the birthplace of coasteering — Pembrokeshire in Wales. Pembrokeshire’s limestone cliffs make it one of the best spots in the UK.
Spain, Portugal and their island territories have coasteering just about everywhere. With warmer water and jaw-dropping coastlines, the conditions beat anything in the UK. I’ve explored long stretches of the Algarve region in Portugal, which, I reluctantly admit, is home to the best coasteering I’ve ever done.
Other locations across the Mediterranean, from Turkey to Sardinia and Malta to Croatia, serve up prime coasteering. Warm waters and cliff after limestone cliff mean new coasteering routes are opening constantly.
Beyond Europe, the map gets patchy. That said, you can still find it in some surprising locations, including Cape Town in South Africa and the Margaret River in Western Australia.
You can even try coasteering in places like Goa and Hong Kong. For the western hemisphere, one dive outfit in Trinidad and Tobago carries the whole load. The United States and Canada have nothing, despite thousands of miles of terrain built for it. My money is on the Gulf and the Caribbean resorts next.
