There are plenty of opportunities for wreck diving in Denmark, night diving, off-beach diving and archaeological trips. Swim with cod fry, the cuckoo wrasse and various other fish on a seabed with plenty of exciting wrecks.
The Baltic Sea provides the best of wreck diving. Given the low salinity, all wooden wrecks are in pristine condition. Also larger wrecks, such as WW1 cruisers, steam ships and other wrecks are in excellent condition. Visibility is usually 10-20 metres.
Check out the wreck of a Foxtrot-class Russian submarine, the U-406. In 1994, U-406 sank in 27 metres/90 feet of water in the North Sea, 22 nautical miles northeast of Hanstholm, reportedly due to a hatch left open while under tow. The sub is a whopping 91.5 metres/300 feet long and sits on her portside.
