Strange things to be seen at sea. Is it a bird? Is it a plane? No it's Reef Despina

Very busy at the lighthouse with a group of older people looking at the geology of the area, school children examining rock pools, photographers and birdwatchers.

There was also a grandfather talking to his granddaughter. I thought he was telling her a story. She was enthralled. It turned out that he was explaining how coal was made.
