30. Radhanagar Beach — Havelock Island, Andaman Islands, India
Regarded as one of Asia’s most exclusive coastal escapes, Radhanagar Beach unfolds along Havelock Island like a private white-sand runway framed by primeval tropical forest. The crystalline waters, warmed year-round, invite leisurely swims while vibrant coral reefs just offshore deliver world-class snorkeling in complete seclusion. Arriving by private charter or luxury ferry from Port Blair only heightens the sense of privileged access. As evening approaches, the beach delivers what many consider the Indian Ocean’s most spectacular sunset — a cascade of amber and rose that transforms the horizon into a living canvas. Boutique eco-resorts nearby offer open-air dining and spa treatments steps from the shore.
