Pembrokeshire's dramatic coastline, part of the UK's only coastal National Park, reveals its full splendour from the water. Boat trips here offer unparalleled views of sea caves, offshore islands and abundant wildlife, including puffins on Skomer, seals around Ramsey, monks on Caldey, gannets on Grassholm and adrenaline-pumping jet boat rides. Whether you're seeking serene wildlife encounters or thrilling speeds, these excursions capture the wild heart of West Wales.
Skomer Island: Puffin Paradise
Skomer Island stands as one of Pembrokeshire's crown jewels for birdwatchers, renowned for its massive puffin population during breeding season. These charismatic black-and-white seabirds nest in burrows across the island's cliffs, emerging to dive for fish in the surrounding waters. Boat trips circle the island, allowing close encounters without landing, as operators like Thousand Islands Expeditions provide expert commentary on the teeming seabird colonies including guillemots and razorbills.
Departing from Martin's Haven, these 1-2 hour cruises offer stunning vistas of the island's rugged contours and the Irish Sea beyond. Sunset puffin trips add a magical touch, with birds silhouetted against the glowing sky. Families and photographers adore these outings for their accessibility and the sheer volume of wildlife visible from the boat.
Ramsey Island: Seals and Dramatic Scenery
The most popular boat trip in Pembrokeshire leads to Ramsey Island, a nature reserve teeming with Atlantic grey seals that bask on rocky shores and playful pups swimming alongside vessels. Operators such as Voyages of Discovery and Pembrokeshire Islands Boat Trips navigate the treacherous Bitches tidal race, showcasing the island's towering cliffs and cascading waterfalls.
These trips from St Justinians near St Davids last about 1.5 hours and often spot porpoises, dolphins and seabirds. The island's isolation fosters a raw, untamed beauty, with boat tours providing the best way to appreciate its wildlife without disturbing habitats. It's an essential for anyone exploring the Pembrokeshire Coast.
Grassholm Island: Gannet Spectacle
Grassholm, home to the largest gannetry in the world with over 40,000 pairs of these elegant white seabirds, delivers a sensory feast on boat trips. The air fills with their calls and the sea churns with diving birds plunging for mackerel. Falcon Boats and similar operators venture into the Celtic Deep for panoramic views of this RSPB reserve, often combining it with whale and dolphin spotting.
Longer expeditions from St Davids or Fishguard highlight the island's chalky cliffs blanketed in guano, a testament to its biodiversity. These trips suit dedicated nature enthusiasts, offering insights into marine ecosystems amid Pembrokeshire's Blue Flag beaches and national park landscapes.
Caldey Island: Monastic Serenity and Seals
Just off Tenby's harbour lies Caldey Island, a peaceful retreat blending spiritual heritage with coastal wildlife. Boat trips from Tenby skim past seal colonies and reveal the island's golden sands, perfume-scented paths and ancient monastery. Monks continue Cistercian traditions here, adding a layer of timeless tranquillity to the voyage.
Short ferry crossings or wildlife cruises allow glimpses of the island's abbey and chocolate factory, popular with families. Combine with dolphin watching for a full day out, immersing in Pembrokeshire's blend of history and nature. Explore more things to do in Tenby nearby.
High-Speed Jet Boat Rides: Adrenaline on the Waves

Saundersfoot Safaris and Fishguard Bay Boat Trips power through waves at up to 40 knots, plunging into sea caves and skimming past dramatic headlands. These 1-hour adventures showcase the coastline's power from a speedster's perspective.
