I had an amazing experience taking my PADI Open Water Diver course at Hydrovius. The lessons were professional and tailored to my needs as a beginner, with extra exercises to reinforce skills. We got to explore a Luftwaffe wreck, torpedo, and plenty of marine life. Kostas, Annie, and Tasos made me feel comfortable from the very first lesson and were very accommodating. If you're looking for a great place for scuba lessons, Leros is a unique destination that is easy to navigate (you're never more than a 10-15 minute drive from the dive center). The island has so much to offer outside of diving, making Hydrovius a complete package. Thank you so much Kostas, Annie, and Tasos!
