A cluster of three tiny, sand-fringed islands off the northeast coast of Sabah serve as nesting sites for endangered green and hawksbill marine turtles. Each night of the year, a handful of females crawl out of the surf to dig a hole and deposit a clutch of eggs above the high-tide mark – a spectacle that may be observed at close quarters on Selingan Island, where the park authorities offer simple chalet-style accommodation. It is also possible to watch park wardens releasing hatchlings back into the sea – one of the most heart-warming spectacles wild Borneo has to offer.
