Imagine arriving at a beach where the water has been scientifically tested for purity, where lifeguards are always on duty, and where the surrounding environment is actively protected by local authorities. That is exactly what a Blue Flag certification guarantees — and for travelers who care about both beauty and safety, these beaches represent the gold standard of coastal destinations worldwide.
From the volcanic black sands of Iceland to the pink-tinged shores of Greece, from the jungle-backed coves of India to the glamorous waterfronts of Brazil, this guide takes you through 30 Blue Flag beaches that deserve a place on every travel itinerary. Each entry includes practical tips on how to get there, what to pack, and what makes the destination worth the journey. Whether you are planning a honeymoon, a family holiday, or a solo backpacking detour, these certified shores will not disappoint.
30. Radhanagar Beach — Havelock Island, Andaman Islands, India
Reaching Radhanagar requires a flight to Port Blair followed by a two-hour ferry to Havelock Island, but every minute of travel pays off the moment you step onto the powdery white sand. The beach stretches for nearly two kilometers along the western coast, backed by dense tropical forest that creates a natural amphitheater of green. Swimming conditions are excellent from November through April, when the sea remains calm and visibility is at its peak. Pack reef-safe sunscreen and water shoes for the rocky patches near the northern end, where snorkelers can spot parrotfish and sea cucumbers. Sunsets here are among the most vivid in Asia, so arrive by late afternoon and claim a spot near the tree line for shade while you wait for the sky to ignite.
