Good thread, some people sure get around...
My list.
WALES:
Numerous sites on the West coast and in Cardigan Bay, Dorothea quarry, Blue hole (no idea where this was), Various muddy puddles
SCOTLAND:
Oban, St Abbs.
AUSTRALIA:
GBR from Townsville to Port Douglas including Cod Hole and the Yongala, Live aboard to Osprey Reef in the Coral sea (North Horn not to be missed!!!). Scientific dive work.
BELIZE:
Barrier reef around South Water Cay. More diving in the name of science. Diving lacking in colour.
EGYPT:
Hurghada area, Sharm El Sheik area, Straits of Tiran, Abu Nuhas wrecks, the Thistlegorm. Marsa Alam region. Deep south liveaboard. Busy region, but still good diving.
MALDIVES:
Ari Atoll (Great for Whale sharks, but weather can really suck!)
TRUK:
Blue Lagoon resort to be recomended. Fabulous diving even if you're not a wreckie.
YAP:
Obligatory Manta pilgrimage.
PALAU:
Beautiful sharks and wall dives. Blue corner not great on every dive, had to do it three times to get it at its best.
PAPUA NEW GUINEA (New Britain):
Excellent live aboard from Rabaul to Walindi. Great diving for everything including stinging plankton!
GRAND CAYMAN:
Stingray city of course, but diving better than I anticipated. Quiet as many americans still staying away.
September this year TAHITI. Rangiroa and Manihi.
Still on the list. SOUTH AFRICA for White Sharks, COCOS ISLAND for all the others...
No kids, a diving partner, and dual London income gets you some fairly decent holidays .
