5 Strange Places To Dive
1) A Former Soviet Labour Camp
Rummu in Estonia is a former Soviet prison camp and open cast mine which naturally flooded after it was abandoned and has become a popular local dive site with good viz and strange buildings and structures to explore.
2) An Active Volcano in Indonesia
The underwater volcano Banua Wuhu rises more than 400m from the sea floor to form a shoal less than 5m below sea level and is located just off the island of Mahengetang in Northern Sulawesi.
3) The Ancient Ruins of Lion City, Qiandao Lake, China
A maze of temples and memorial arches of the ancient Chinese city of Shi Cheng near Five Lion Mountain disappeared in 1959 when a vast hydroelectric scheme dammed the valley. Today it is a dive back to Imperial China.
4) A Flooded Former Slate Mine in Germany
Underneath a busy ski resort this former slate mine in Willingen might be a tad chilly (5ºC), but the viz is great and there is lots of machinery and the like to check out.
5) Where Two Continents Clash
Swim between two continents. The Silfra fissure in Iceland's Thingvellier National Park is where the North American and Eurasian tectonic plates meet. The viz is staggering (more than 100m) and each year the crack gets 2cm wider.
