Located at a family resort on the Adriatic Sea, this US-style camp hosts children from 30 different countries and promotes cross-cultural friendships by having no more than three of the same nationality per cabin. Camp language is English and there’s lots going on to bring kids together, with watersports, performing arts and gymnastics. Teen-specific courses include sailing, rafting, kayaking and kitesurfing.
