Snorkelling with seals


We have created a new website for our seal snorkelling trips.

Come snorkelling and have a close encounter with a seal! Watching seals swim gracefully and effortlessly in their natural environment is a fabulous, award winning wildlife experience.
A diving instructor will guide and assist you. All equipment is provided. No previous snorkelling experience is required, but you should be confident to swim in open water. The minimum age is 8 and all children need to be accompanied by an adult. These three hours trips are always popular so book early in your holiday to avoid disappointment. To book call 01720 422848.
  • Price £49 (minimum of two for a trip).
  • For groups of four or more, price £45 per person.
  • Hire of action camera - £15
  • We charge £22 per person for those who want to watch their party snorkelling but don't want to get in the water. Our minimum age for watching is six.
  • Payment by cash, cheque or BACS only.
If you're not staying on St Martin's and your trip is in the morning, we do offer a pick up service at £8 per person. We can collect you from St Mary's or Old Grimsby, Tresco. You will be travelling in our RIB so please wear appropriate protective clothing for the weather conditions. You will return to your island on a scheduled tripper boat at your own expense.
Please note that trips will be cancelled if our staff consider that the weather and sea conditions make it unsuitable for snorkelling.


Anna and Tim are accredited WiSe (WIldlife SchemE) operators. For more information about the WiSe scheme visit

It is possible to have an unguided dive with the seals if you have a recognised diving qualification and your own diving equipment. We can provide wet suits, cylinders and weight belts. We charge £75 for an unguided dive. Please note that snorkelling trips are run separately to diving trips and we cannot combine the two.
