Ojamo lime mine in Finland.

Far below Helsinki lies an underworld playground.

Ojamo lime mine is about 40 miles west of Helsinki, Finland. Today the water-filled mine looks just like any other small forest lake. Underground, the tunnels stretch for miles. The shallowest start at a depth of about 90 feet — the mine reaches a depth of more than 800 feet at the bottom of the main shaft, with tiny tunnels and huge mining halls throughout.

Although Ojamo is a very popular diving site in Finland, some sections have been seen by only a handful of divers, since they are located at a depth of almost 450 feet. Bring your drysuit with you:Decompression in 39-degree water takes hours.
