Until recently one of most interesting natural landmarks in Saint Martin was Le Trou de David (originally – Trou du Diable). Unfortunately this magnificent sinkhole collapsed.

This natural hole formed by a collapse of a large sea cave chamber. Le Trou de David was a hole with nearly vertical walls, with a diameter of some 25 m, some 10 m deep. It was divided from the sea with a narrow wall. There were two natural arches in this wall – one was deep enough to allow swimming in and out of the hole to the sea.

When the sea is rough, water in the hole seems to be boiling – hence the original name of the hole – Trou du Diable (Devil’s Hole).

On the walls of the sinkhole often were sitting large iguanas (Iguana iguana) – an invasive species. Reef outside the sinkhole is very interesting for snorkeling and diving – it has interesting rock formations and abundant sea life.

Nothing is forever. Natural arches at the sea are shortlived landmarks – sooner or later the support of the arches is destabilized by erosion. This happened with Le Trou de David as well – after heavy rains, it collapsed in the time period between November 29 and December 5, 2011.
