Le Morne, or “the mournful one”, is deeply important to Mauritian culture. In the 19th century, it was home to a group of escaped slaves, who used the difficult terrain of the mountain as a hideout and fortress. These people converted the caves of the mountain into permanent shelters, and used the vegetation to avoid recapture.
Legend has it that colonizers of this area were ignorant of the abolition of slavery in 1835, and panicked when they saw soldiers making their way towards the mountain. Fearing that they were to be taken back into captivity, they chose instead to thrown themselves off the mountain in large numbers. Whether truth or legend, this was how the mountain earned its name, and as a result was conferred the status of UNESCO World Heritage Site in 2008.
The trailhead to this cache begins at the southern beach of the peninsula. The cache is hidden in a rock formation at 255 m of elevation (about halfway up the mountain), at a quiet spot that provides an excellent panoramic view of the surrounding area. There's no need to leave the trail or do anything dangerous in order to get the cache.
