Skill level:
All divers
Maximum depth:
98.4 ft / 30 m
Best season:
June to late September
By boat from Kos or Kalymnos island
Pserimos is a small, rocky island located between Kos and Kalymnos, near the coasts of Turkey and is part of the Dodecanese group of islands. Mainly mountainous and with no real roads, noisy cars, loud bars and crowds, Pserimos sounds like heaven for those who just want to relax and bathe in the crystal clear waters of the Aegean, while enjoying the serenity of a place that only a few people visit, even in high summer season.

Easily accessed by boat from Kos or Kalymnos, the island is an excellent get away and has many great diving sites. The Mediterranean climate provides hot, dry summers with high winds and an average temperature of 32°C/89°F, while the temperature of the water is around 27°C/80°F.

Located on the southeast side of the island, the Thor Star wreck lies on the sandy bottom of the sea and is broken into three pieces. Thor Star was a cargo ship build in 1965, with an overall length of 241 ft/3.5 m and was abandoned in Pserimos in 1997. After a few years it sunk, probably because of strong weather conditions – the reasons the ship sunk still remain unknown- and is now one of the favorite diving destinations in the area.

Located at a maximum depth of 98.4 ft/30 m, the wreck is in good condition and suitable for both novices and experienced divers. The bow of the ship is positioned in shallow waters, about 16 ft/5 m deep, while the second section goes down to 49 ft/15 m deep. For the most daring and qualified divers, the third section offers more exciting exploration options, as you can swim around the propeller and penetrate the ship’s bridge.

Thor Star wreck is surrounded by an outstanding biodiversity and many big fishes find shelter within its hull. Divers will come across damsel fish, tunas, jacks, snappers as well as the impressive thuridilla hopei sea slugs. With excellent visibility and low sea current, this is a very interesting dive for all wreck diving enthusiasts.
