Bucket list experience:

Last updated: 19 April, 2023

If you’ve ever wanted to swim with a seal, this is a great place to tick it off your bucket list. The crystal-clear waters around the Isles of Scilly are rich in sealife – an ideal habitat for grey seals, who are curious and playful around humans.

Snorkelers can encounter these intelligent creatures up close, watching as they glide effortlessly through the water and interact with each other. A peaceful yet exhilarating experience.
