There are several water parks along the Black Sea coast, but we think most youngsters will agree that these are among the best. A day out for all the family can be quite pricey, not to mention what being out in the bright sun and water all day can do to your kids (don't forget the sun protection) - some parks offer cheaper admission after 2 or 3pm - so it is worth checking out. Most water parks do not allow you to take in your own food and drinks.
