Plan your visit

Natural snorkel pools at the east end

The snorkelling here is around the chalk-rock outcrops at the eastern end of the beach, below the white cliffs that run toward Dunluce Castle. On a calm, clear day you can enter easily from the sand and explore the shallow pools and gullies between the rocks. It suits confident swimmers and snorkellers who are comfortable in cold, open sea, not first-timers. You may spot kelp, small fish, crabs and other rock-pool life, but sightings are never guaranteed and visibility depends entirely on swell and recent weather. For a guided alternative, Aquaholics in Portrush Harbour run licensed boat snorkel trips along this stretch of coast with kit and a briefing provided.

Good to know before you go:

Conditions here change with the weather and the tide, and visibility changes with them — clear and calm one day, murky and rough the next. Check a forecast and a tide table before you set off. This is a self-access site with no lifeguard, so match it to the experience you actually have, go with a buddy, and never dive alone.

Before you set off

What to bring

  • 🗺️A proper planA buddy, a tide check and a weather check. Wild sites have no lifeguard and nobody expecting you.
  • ☕Warm layers and a hot drinkThe water is cold all year. Dry clothes and something hot afterwards make the whole day.
  • 🏖️A towelAnd somewhere to put wet kit for the drive home.
  • 🤿An honest look at your experienceMatch the site to the training you actually have. Plenty of people start with a try-dive instead.

The story

About it

Whiterocks forms the eastern end of Portrush's East Strand, named for the white chalk and limestone cliffs that have been carved over centuries into arches, caves and outcrops such as the Wishing Arch and Elephant Rock. The beach is a regular Blue Flag award winner and part of the council-managed Whiterocks Coastal Park on the Causeway Coastal Route.

It is a popular spot for surfing, diving, kayaking and swimming, with seasonal RNLI lifeguard cover on the main beach. The natural rock pools at the eastern end give snorkellers a calm-day option, while licensed Portrush operators run guided boat snorkel trips to the nearby caves and rock formations.
