If you are a fan of underwater exploration, and your children are old enough, you can discover the gorgeous underwater world of Crete through scuba diving courses.
You can also enjoy sea kayaking on the south coast. Crete also offers plenty of surfing opportunities – wind surfing, paddle surfing and kite surfing – in locations including Elafonisi, Falassarna, Agia Marina, Plakias, Amoudara and Ierapetra.
