When people think of top snorkelling destinations, their minds often drift to exotic shores or the turquoise waters of the Mediterranean. But for those in the know, Collywell Bay in Northumberland offers a local alternative that’s just as magical — and far closer to home.
This quiet, picturesque bay near Seaton Sluice has become a hotspot for UK snorkelers in recent years. From its vibrant marine life to calm, clear waters, Collywell Bay ticks all the boxes for a top-notch snorkelling experience. But what exactly makes it such a magnet for underwater adventurers?
Crystal-Clear Waters and Shallow Depths
One of the biggest draws of Collywell Bay is its surprisingly clear water, especially during the warmer months. The clarity is enhanced by the bay’s rocky seabed, which reduces sediment and provides an ideal backdrop for spotting fish and other marine creatures.
Thanks to its shallow depth, snorkelers don’t need to be experienced divers to enjoy the underwater scenery. This makes the bay perfect for beginners, families with children, or anyone looking for a relaxing snorkel without needing full scuba gear.
A Rich Tapestry of Marine Life
Collywell Bay is a haven for biodiversity. Beneath the surface, snorkelers can expect to encounter a vibrant array of sea life, including:
-
Colourful wrasse, gobies, and blennies darting between rocks
-
Starfish and crabs nestled in crevices
-
Anemones swaying gently in the currents
-
Even the occasional curious grey seal
The intertidal rock pools also offer rich pickings for marine enthusiasts, especially during low tide when life teems just below the surface.
Natural Shelter from the Elements
Unlike more exposed stretches of the Northumberland coast, Collywell Bay benefits from a naturally sheltered position. The surrounding cliffs and outcrops protect the bay from strong winds and currents, creating a safe and stable environment for snorkelers to explore.
This makes it a year-round favourite, although late spring to early autumn remains the prime time to visit — especially when the sea is calm and visibility is at its best.
Easy Access for All
One of the most underrated aspects of Collywell Bay is its accessibility. Located just a stone’s throw from the village of Seaton Sluice, the bay is easy to reach with free public parking nearby and no long hikes required. You can be in the water within minutes of arriving, which makes spontaneous snorkelling sessions totally feasible.
This convenience is particularly attractive for local snorkelers from Newcastle, North Tyneside, and beyond.
Word of Mouth and Community Buzz
Collywell Bay’s popularity has grown largely through local snorkelling groups and social media sharing. From Facebook recommendations to GoPro footage on Instagram and YouTube, more and more adventurers are discovering the magic of this coastal gem.
Snorkelling clubs in the North East often list Collywell as a go-to site for training and exploration, further cementing its status as a snorkeller’s dream spot.
A Stunning Backdrop Above and Below Water
The natural beauty of Collywell Bay is not limited to what lies beneath. Above the surface, snorkelers and visitors alike are treated to rugged cliffs, sea stacks, and sweeping coastal views. It’s a scenic haven for wildlife too — keep your eyes peeled for seabirds and the occasional porpoise offshore.
After a session in the water, a stroll along the nearby beach or a visit to one of Seaton Sluice’s cosy cafes makes for the perfect wind-down.
