Radhanagar Beach — Havelock Island, Andaman Islands, India
Tucked away in the remote Andaman archipelago, Radhanagar is the kind of beach that whispers rather than shouts. Pristine white sand stretches beneath a canopy of towering tropical trees, creating natural shade that makes golden-hour lounging an art form. The water shifts between shades of emerald and sapphire depending on the light, and the snorkeling around nearby coral formations reveals an underwater world that feels untouched by time. What truly sets Radhanagar apart is its sunset spectacle — a nightly performance of tangerine and violet that draws visitors to the shoreline like a curtain call. Reaching the island requires a ferry from Port Blair, but that journey across the Bay of Bengal only heightens the sense of arriving somewhere genuinely special.
