Blairgowrie Pier
Australia
Blairgowrie Pier is a fantastic site for photographers, due to the abundant macro life. It's also a popular training site, due to its sheltered position and manageable depth range (2-7m). The pier pylons and sea wall are heavily encrusted with sponges - home to many Seahorses and Nudibranchs - even the odd Tasselled Anglerfish. Ledges and hidey holes make great homes for numerous species of Rays, as well as Octopus, Squid and Giant Cuttlefish. You can also see Stargazers, Flathead, Decorator Crabs, Goatfish and many others. Blairgowrie Pier often hosts the annual Giant Spider Crab march in May-June each year. Thousands of crabs gather in the shallow waters to moult.
Playa del Cabrón
Spain
This is a fun dive to 12m maximum, beginning with an easy walk from the beach; we then follow the reef out towards the headland, which forms the natural shelter for the bay. As conditions here are invariably calm this makes it the perfect site for beginners or trainees, and those of you who have been out of the water for some time. Yet many experienced divers and underwater photographers also enjoy the bay because of the diversity of life and excellent light conditions There is a wide range of sea-life ranging from the ever present shoals of atlantic and blue-fin damselfish, bream, parrotfish, wrasse, lizardfish and pufferfish. More diligent searching will reward the diver with clams, razorfish, juvenile barracudas, trumpetfish, wide-eyed flounders, common stingrays, octopus, as well as cuttleFish and many other species. In spring many predators enter the bay at night to feed on the spawning fish. Some stay during the day giving close-ups of stingrays, anglesharks, barracuda and weaver fish
St. Didier Wreck
Turkey
St Didier has been sunked by an English aeroplane in 4th of July 1941 durin WW2. The ship whose real name was "Saint Didier", is lying right under the buoy which is an untired guard of the Antalya yatch harbour, 1 km away from there. With her bow looking to south and stern looking to the north, she is lying between 18 and 34 meters with an 35 degrees angle to the starport side. Her length is around 70 meters. In the studies done between 1946 and 1974 , they salvaged the skeletons and a lot of the ship's cargo. There is nothing much left as an artifact in the wreck becase of the later dives where everyone took some part of the wreck as a souvenier. But still she is getting the interest of the wreck divers.

Bergse Diepsluis
Netherlands
Many believe the waters surrounding The Netherlands have more underwater life than the Mediterranean Sea. After diving in The Oosterschelde, you might believe it too. Bergse Diepsluis is less challenging than other dive sites in this area, but still rich with life. Situated in a tributary of The Oosterschelde, there is little to no tidal current, making it an ideal breeding ground for cuttlefish and squid. Colourful anemones, crustaceans and invertebrates are abundant year-round. Spring is the best time to see cuttlefish, but wait until the water temperature reaches 12°C/53°F. The maximum depth is 19 metres/62 feet. Average visibility is 4 metres/13 feet. Photo Credit: Daniel Versteeg
