The Unicorn Wreck is a 55 meter Japanese refrigerated cargo vessel sitting nearly upright only 30 minutes north of Koh Tao.

The top of the bow is at 37 meters, maximum depth 50 metres. Perfect for experienced recreational divers, technical diver training or a tec day trip.

The Unicorn arrived at Koh Tao in 1989, anchored for a few days and then suddenly sunk. An insurance claim for canned tuna was made, but when a team of divers dived the wreck they found animal feed.

We called her the Unicorn for years but recently discovered some medical items marked Hishi-Daiya Maru.
