Britain’s coastline offers some of Europe’s most underrated snorkelling, from colourful kelp forests and playful seals to seahorses, octopus and crystal-clear island waters. Choosing the right snorkelling equipment makes a huge difference—not only for comfort and warmth, but also for safety and enjoyment in our cooler seas.
Whether you’re buying your very first snorkel set or upgrading to premium equipment, this guide covers everything you need to know, including budget and high-end product recommendations, material comparisons, what features actually matter, and the best places around the British Isles to put your new gear to use.
Why Snorkelling in the UK Is Worth It
Many people assume snorkelling is only worthwhile in tropical countries. In reality, the British Isles are home to an astonishing variety of marine life.
Depending on where you visit, you could encounter:
- Grey seals
- Common seals
- Cuttlefish
- Octopus
- Spider crabs

Visibility can range from 3 metres to over 20 metres depending on location, tides and weather, with the southwest of England, Wales and Scottish islands often offering the clearest conditions.

Buying purely on price often leads to uncomfortable masks, leaking snorkels and cold-water misery.

For most people snorkelling around Britain, the sweet spot is a mid-range setup featuring a silicone mask with tempered glass lenses, a dry-top snorkel, open-heel fins paired with neoprene boots, and a 5 mm wetsuit.

Choosing well-fitting gear means less time clearing water from your mask and more time enjoying Britain’s remarkable underwater world, from playful seals around Lundy Island to colourful kelp forests in Cornwall and the crystal-clear seas of the Isles of Scilly.
