The topography of St. Maarten is mountainous with lush, green hillsides that slope upward to heights well above 200m. The highest peak is Wymouth Hill (382.7m or 1,255.57ft) followed by Sentry Hill (341.1m or 1,119.094 ft) and St. Peters Hill (316.2m or 1,037.401 ft).
This centrally-located ring of hills in the shape of a horse shoe forms a Cul de Sac in the valley below. Along the St. Peters - Sentry Hill ridge is the primary seasonal rain forest with a variety of flora and (avi-) fauna. There are different species of mosses, lichens, fungi and flowering plants such as bromeliads and orchids. Butterflies, moths, dragon flies and humming birds are just some of the animals found in the forest.
Sentry Hill also boasts impressive geological features, large rock formations that form the peak of the hill with crevices and caves that serve as nesting areas for bats and geckos. Sentry Hill offers magnificent bird’s eye view of Philipsburg in the east and westerly Cole Bay and environs.
