Diving in the Garvellachs Islands of West Scotland can be recommended and be really enjoyed. However, with strong rapidly-changing currents in a mountainous sea bed terrain, one must not take anything for granted and should always be on guard for the unknown. One can teach from experience but experience can’t be bought – only experienced. I’d like to share the experience that my wife, Gill, and I have had in the hope that it may prove beneficial to other divers that may wish to learn from it.
