Lambir Hills, half an hour south of Miri, holds a quiet world record: research plots here have documented more tree species per hectare than almost any forest ever studied, making this modest range of sandstone hills one of the most biodiverse places on the planet.
For visitors the park is blissfully simple — a network of well-marked trails linking a series of waterfalls, the closest and most beloved being Latak, whose deep pool below a 25-metre drop is Miri's favourite natural swimming hole.
