Dive in to Scotland’s Living Seas!

Experience the wonder beneath the waves on one of our award-winning snorkel trails. We have selected nine sites along the north west highlands coast around Ullapool, and six sites on the Isle of Harris that showcase the amazing diversity of Scotland’s seas.

Bursting with marine life, you could see everything from small sea squirts, sponges and anemones right up to dolphins, whales and harmless basking sharks.

Before you go snorkelling, make sure you read our Snorkel Safety Information below so that you know how to be a safe and responsible snorkeller, and check out the Useful Links for further information on snorkelling and some of the marine life that you might see.

We’ve put together a handy leaflet which tells you a little bit about each of the snorkel trail sites and some of the wildlife that you might see.

Stay safe

Snorkelling can be dangerous and is done entirely at your own risk. Information is provided free of charge; it is your responsibility to check the conditions present on the day and assess whether it is safe to snorkel.

Snorkel Safety

Here are some top tips to being a safe and responsible snorkeller…

Before you go

  • Check the conditions: be aware of tides, water temperatures, currents and weather forecast before you leave.
  • Take a friend: never snorkel alone and always tell people where you are going.
  • Know who to contact: find out where the nearest medical and/or coastguard facility is and note down who to contact in an emergency.

At the beach

  • Know your surroundings: check what the weather and tides are doing, and identify a landmark for reference.
  • Use the right equipment: only use good quality and well-fitting equipment – mask, snorkel and fins.
  • Wear the right protection: a wetsuit will keep you warm and protect you against jellyfish stings. If it’s sunny, remember to cream up!

In the water

Follow the Snorkeller’s Code:

  • Do not remove seaweed or animals from the rock or from their homes.
  • Take care not to kick sealife with fins or stand on delicate animals.
  • Observe animals where they live and don’t take anything away with you.
