Nestled at the most southwestern tip of Wales, Pembrokeshire is a hidden ocean gem. Known for its craggy coastline and gold sandy beaches, this mythical county was named one of National Geographic’s top coastal destinations in the world.

“Above the waves, life is abundant. In early summer, the cliffs are packed with seabirds and dappled with soft pastel hues from blossoming clumps of sea thrift. Along its beaches, seals can be spotted hauled out sneaking a nap, whilst rock pools brim with mini-beasts, from snakelock anemones to tompot blennies. For those willing to venture that bit further offshore, life in its deep waters is just as spectacular, harbouring some of the most spectacular marine wildlife in the UK such as blue sharks.”

Charlie Young - Saltwater Britain

For this inaugural expedition, we’re partnering with Celtic Deep – a responsible travel charter run by a team of conservationists – to take you on a week-long expedition to explore Pembrokeshire’s seas and encounter some of its most iconic marine wildlife.

Your SWB guides

Joining you on this trip will be both Charlie Young AND Francesca Page!

Charlie is a marine scientist, diver, expedition leader and wildlife presenter based in the UK. Passionate about inspiring people to care for the ocean, Charlie uses her skills as a scientist and communicator to champion change for our big blue.

Charlie founded #SaltwaterBritain as a campaign and micro-adventure series to raise awareness of UK marine wildlife and habitats. Together with Blue Ventures we’re bringing this movement to life via a series of immersive ocean expeditions that blend adventure with science to inspire a new wave of ocean advocates in the UK.

Francesca is an internationally renowned artist, published illustrator, award-winning photographer, storyteller and dive professional. She creates incredible large scale watercolour and gouache paintings of wildlife interacting with their environment based on her own encounters. Her adventures, photos and stories inspire her Projects, which aim to capture the environment explored. Her work has featured in Dive Magazine UK, and she is the winner of the travel category in the National Geographic Traveller competition 2020. She illustrated the animations for the Seaspiracy documentary on Netflix, and is proud to have worked with some amazing organisations and brands over the years.

Francesca’s desire for adventure, storytelling and creating personal connections with my subject matter drives my work and makes her the perfect SWB guide! Over the years photography has become a love for her and for her art an important tool to capture the world around me. Indeed, photography and painting go hand in hand for her creative practice. Whether she is diving into the blue or exploring the magic found on land, photography is such an important tool to help capture these special and intimate moments. Francesca believe’s photography and art are both powerful ways to help connect others to the natural world and, she hopes, to inspire people to want to help protect it.


Activities to expect:

As with any UK based adventure our exact itinerary is subject to changes based on weather conditions but across the week we hope to have:

  • 5 days on and in the water including 2 days searching the Celtic Deep for blue sharks, porbeagle sharks, sunfish, minke & fin whales, common & bottlenose dolphins and even bluefin tuna, orca or humpbacks!
  • Seabird boat excursions around Pembrokeshire’s islands; Grassholm (gannet colony), Skomer (puffins, guillemots and razorbills), Skokholm and the Smalls.
  • Seal swimming around Skomer and Skokholm.
  • Kelp bed explorations.
  • Treks to secret spots along Pembrokeshire’s stunning 186-mile coastline.
  • Marine conservation expert-led presentations, films and workshops.

Note – We’ll get in the water as often as it’s safe to do so (all activities are optional of course)


Ocean adventures with impact

As well as all profits from your adventure supporting grassroots international marine conservation, your adventure will give you a brilliant insight into the issues facing our ocean at home and abroad.

The active conservation elements of the week will include on-water activities and a scheduled series of optional lectures and interactive workshops, beach clean-ups and visits to local conservation projects. The content will have UK focus with a global marine conservation overview.


For the duration of the trip, we will be staying at Dale Fort!

Set high on the cliffs within the Pembrokeshire Coast National Park, Dale Fort has superb views over the sea. Built in 1856 to defend the Milford Haven waterway against invasion, it has been a field centre since 1948 and is a short walk away from the beautiful seaside village of Dale.

It’s from here that we will be launching into the deep each day, making it perfectly situated for this trip.

Prices are based on two people sharing a large twin room. Single supplements may be available on request.

What to bring

Kit isn’t available to hire and so there are some things you will need.

Sea temperatures average at 11 degrees in June. Therefore we advise you to bring:

  • A 5mm, full-length wetsuit (7mm is recommended) or a 2 piece freediving suit.
  • Gloves, hood, fins, mask and snorkel are needed – preferably all black or dark coloured as the sharks are very attracted to bright colours.
  • Warm coat or dry robe.

When onboard it is also recommended you bring a change of clothes, SPF 50, sunglasses, hat, food and plenty of water for the day. Facemasks will also be required to adhere to COVID regulations.

Celtic Deep have a great kit guide here if you’re in need of recommendations.
