​Snorkelling & Wildlife Safaris

Our snorkelling and wildlife safari swims allow you see what's under the water as well as on top of it. You'll be swimming as well as snorkelling and duck diving around the beautiful Pembrokeshire coast.

Previous experience is desirable but not essential as we will tailor the snorkelling route to your ability as well as the sea conditions. As always, it helps if you have your own snorkelling gear but again, we have a small stock of equipment we can rent at a reasonable cost.

There's plenty of wildlife to see, from crabs to jellyfish to small mud sharks, aka 'dog fish'. Maybe even a seal or dolphin depending on the time of year.  Click here to learn more about the wildlife in the area.

We'll explore sea caves and arches, swimming and diving through them and checking out deserted beaches on the way. 

​Coastal Adventure Swims

We partner with a local charter boat company to provide you with the ultimate in open water swimming experiences.

Meeting at Neyland Marina, we will embark on a sea swimming trip to remember, which is not only about the swimming experience but a complete sea life adventure, you never know what you will come across on, or in, the water.

Boat Facilities

The ‘Celtic Wildcat’ is a 10.5 meter (36’) long Catamaran with twin 300hp engines. There is ample room on the deck for up to 12 people.

The boat is designed with a walk around wheelhouse which along with the on deck seating allows plenty of room to chill out and take in the spectacular views that the Pembrokeshire coast has to offer. There is seating in the cabin as well.

There are also facilities for making hot tea and coffee as well as refreshments and snacks offered as part of our swim packages.

Your adventure will start from Neyland Marina, which has free parking a café and restaurant on site. The marina also has showers which will be available to you at the end of the day. There is a shower and toilet on the boat as well as an interior area for warmth and shelter if needed.

The Swim Plan

All of our swims have been explored and assessed for risk and hazards, which are documented and known by the swim guides. When everyone's ready we will get kitted up, split into your groups and review the swim plan with your swim guides. We will then enter the water and start the swim according to the swim plan. Once in we are sure you will be amazed by the clear visibility and beautiful underwater and coastal scenery.

​Marine Wildlife

The wildlife safari and coastal adventure swims follow the coast line of the either a nearby island or the mainland but can in some cases involve swims between islets or across bays. All you have around you is miles of open ocean! You will also get to see various other marine animals that live on the land or in the coastal zone: puffins, razorbills, crabs, seals, dogfish, jelly fish, to name a few.

The wildlife safari swims will take in a number of different coastal environments from shallow beaches to rocky drop offs to about 7 or 8 metres depth. You will see a range of wildlife including those listed here and depending on the time of year, possibly seals too.

The day long Cost Adventure Swims are more than just a sea swim, they are a complete sea life adventure with loads to see above and below the water. It's not uncommon to see seals on the day long boat trips, even whales and dolphins.

Multiple Swims

Our Coastal Adventure Swims are a full day out and allow you to sample a range of swimming environments, from island bays to coastline cliff swims, to deserted beaches.

Over the course of the day we will do multiple swims moving to new locations each time. Swims will follow the same structured format and a planned route each time and your swim guide will review this with you before you get in.

If you are tired or would rather stay in the boat then of course this is OK. If at any time you wish to leave the water, then you can do so, there's plenty to see on the surface too!

Swim Breaks & Refreshments

After our coastal adventure swims we go back to the boat and get warmed up. We recommend bringing coats you can put on over your wetsuit to get warm as quickly as possible. A DryRobe is great for this. Check out this link for more info.

We will have hot drinks and snacks on the boat and chat about all the awesome stuff we just saw! You can bring your own packed lunches of course. It goes without saying, please dispose of rubbish responsibly.

Breaks are normally 45-60 minutes and when everyone is ready we will move the boat to a new location, depending on the weather and sea conditions. Once we're ready, off we go again!

The one thing we have absolutely no control over is the great British weather!

The British weather is notoriously unpredictable, especially in at sea; it can be foggy one minute, brilliant sunshine the next; and the other way round: you may start the day in glorious sunshine and end in a howling gale.

For us, this is just part of the adventure and being well prepared can help minimise the downside of a bad weather turn, but it is important to understand this is not something we can control.

Your safety and comfort is our concern, so if the weather is deemed to be too poor to reach the destinations and have an enjoyable experience doing so, we have contingency sites that we can go to instead.

However, even though these packages run in the summer/autumn months, we recommend preparing for weather extremes!

What to Bring

  • Mandatory swim kit: triathlon style wetsuit, googles, hat, swim tow. Sorry, no skin swimming.
  • Neoprene socks, skull cap and gloves if needed.
  • Dry clothes. We recommend warm weather gear too, even if it is the height of summer.
  • A waterproof/windproof jacket to keep off the wind or spray if it turns cold. A DryRobe is great for this.
  • More information on correct kit for sea swimming can be found here.
  • Underwater action cam if you have one, if not there are action cams available for rent.
  • Camera, with a good zoom lense if you have it, there is lots to see on the coast line.
  • Binoculars if you have them, you can do plenty of wildlife watching from the boat.
  • Snacks/packed lunch for the day, there will be plenty of tea/coffee/snacks on board.
  • Sun cream, sun glasses, sun hat if needed..
  • An open mind and sense of adventure!
