Heard the one about the Blue Hole? Or maybe it was the Blue Lagoon? I’m sure most of us have heard stories of ‘secret’ dive sites before; they normally surface after a few beers following a hard days diving. Those telling the story will often reminisce about a time when diving involved a degree of exploration and adventure! With that in mind I decided to seek out some of these lost treasures for myself and set out on a series of UK Diving Adventures!
