Highlights

Outing Highlights

THE WILDLIFE

Up-close encounters with a resident seal colony

Trips visit the Skerries Islands to snorkel and swim among the resident seals; interactions with curious island seals are common and are a defining feature of the outing.

THE UNDERWATER

Kelp forests, underwater canyons and cave passages

Participants explore lush kelp forests and—depending on experience—can descend to caverns, canyons and deep drop-offs that reward more confident snorkelers and freedivers with dramatic underwater topography.

THE BOAT EXPERIENCE

A small safari boat with in-water instructor support

The operator runs the trip from a safari-style boat; instructors enter the water with guests and have buoyancy aids available, while the vessel remains in close proximity for rest and retrieval.

What the day feels like

What the outing feels like

You meet at Portrush Harbour, kit up with provided equipment and receive safety and wildlife briefing before boarding the safari boat. The short transit brings you to the Skerries Islands; after entering the water you drift through swaying kelp and among inquisitive seals, guided closely by instructors. Expect roughly ninety minutes in the water before returning to harbour to warm up and debrief ashore.

Suitability

Who it's for

Who this outing suits — and who should think twice.

1
Beginner snorkelers & confident swimmersA good match if you can swim 100 metres unaided; beginners are supported by in-water instructors and buoyancy aids and can experience the kelp and seals under close supervision.
2
Freedivers & experienced snorkelersWell suited for experienced swimmers who want to explore underwater caverns, canyons and deeper features—these participants can push beyond the kelp forest under guide oversight.
3
Those with limited mobilityNot ideal if you cannot climb a ladder back onto the boat or lack the moderate mobility required to enter and exit the water; the operator can request you remain on board for safety.
4
People with relevant medical conditionsShould disclose any medical issues in advance; medical conditions that could impact the activity need to be advised to the operator and may affect eligibility to enter the water.
