Flush with fascinating endemic species, steamy rainforests, towering ancient baobab trees and orchids exploding in a riot of colour, Madagascar is well-known for its out-of-this-world biodiversity. And yet despite being the fourth-largest island in the world, there are still certain pockets of the beguiling country that remain mercifully undiscovered. One such region is the deliciously remote northwest, home to Tsingy de Namoroka National Park. An expansive haven of six distinct ecosystems ranging from riverine forest to bamboo groves, plus an extensive cave network and a series of unique tsingy limestone rock formations carved into shape by the elements, the rugged, off-the-beaten-track park is accessible just seven months of the year. Until now, the closest accommodation was a four-hour drive away, but the opening of Namoroka Tsingy Camp is set to change that.
