The topography of St. Maarten is mountainous with lush, green hillsides that slope upward to heights well above 200 meters. The highest peak is Weymouth Hill (382 meters or 1,255 feet) followed by Sentry Hill (341 meters or 1,119 feet) and St. Peters Hill (316 meters or 1,037 feet).
This centrally located ring of hills in the shape of a horseshoe forms a Cul de Sac in the valley below. Along the St. Peters – Sentry Hill ridge is the primary seasonal rainforest with a variety of flora and fauna. There are different species of mosses, lichens, fungi and flowering plants such as bromeliads and orchids. Butterflies, moths, dragonflies and hummingbirds 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 a magnificent bird’s eye view of Philipsburg in the east and westerly Cole Bay and environs.
