Redzak, Heidelberg, Germany; October 2019


I made two dives with Sea World Diving Center. Absolutely Fabulous! Very well Organized. Both dive sites had very interesting marine life and underwater landscapes. Can highly recommend!

Fantastic experience, a must do

Absolutely fantastic! The staff are extremely friendly and make diving very straightforward for beginners. The time spent in the water is brilliant and the experience is immersive. Would definitely recommend to anyone who would like to see various sea creatures. A must do on your holiday!

Great Diving!

On holiday at Ikos Aria. The diving center is on the beach right outside the hotel. I am an advanced open water diver but only thirteen years old. None of my family dive. The team at the center have made me very welcome and really looked after me. I have done three dives in my first week and it has been amazing. Fantastic visibility, warm water even at 18 meters deep, incredible rock formations and lots of fish, including moray eels and the invading lion fish.

Great diving experience at Kefalos Bay - Ikos Aria

Our daughter Clara (10years) finalized the PADI Scuba Diver course at Sea World Diving Center Kos!

From the first to the last dive it was a great adventure and experience for her!
Especially Ian made the Diving experience unforgettable for her!

But also for the experienced divers the Diving Center provides new equipment, detailed briefings, a good boat and interesting dive sites.

Tanja, George, Dimitris & Ian are a great and experienced team!
Hope to be back next year!
