The North Sentinel Island in the Bay of Bengal is arguably one of the most isolated places on earth, both through remote location and inaccessible population. The small island of around 60 square km is located off the Norwest coast of Indonesia and has been far from explored.

While few places are truly "undiscovered" in the age of satellite maps, several islands remain off the mass-tourism radar in 2026. Tiwai Island in Sierra Leone is a rising star for 2026; a recently designated UNESCO World Heritage site, it is an inland river island home to rare pygmy hippos and diverse primates. For a more remote "ocean" feel, Jaco Island in East Timor is considered sacred by locals, meaning no one lives there, but tourists can take day trips to its pristine, untouched beaches. In Europe, Vis Island in Croatia is emerging as a "not-hot" alternative to crowded Hvar, offering a slower pace and preserved military tunnels. For those seeking true isolation, the Antipodes Islands of New Zealand are nearly impossible to visit due to strict conservation rules, making them some of the most "untouched" volcanic landscapes left on Earth.
