Crete has retained its position as Greece's leading region for certified beaches in 2026, with 154 Blue Flag awards across the island. The Blue Flag is an internationally recognized certification granted to beaches that meet strict standards for water quality, environmental management, safety, and facilities. Rethymno prefecture contributes a significant share of these designations. For visitors, Blue Flag beaches guarantee clean swimming water tested regularly throughout the season, lifeguard presence, accessible facilities, and proper waste management. When choosing where to swim in Crete, looking for the Blue Flag pole at the beach entrance is a reliable indicator of quality and safety. The certification applies for the current 2026 summer season.
