The Quill is the dormant volcano that forms the southern third of St Eustatius, rising to 601 metres above the flat agricultural plateau that takes up most of the island. The cone is steep and symmetrical, the crater intact, and the interior of the crater contains a lush pocket of rainforest that feels extraordinary given how dry the surrounding island is.
The hike from the trailhead on the eastern slope to the crater rim takes about 45 minutes to an hour at a steady pace. From the rim, you can descend into the crater on a rougher trail through increasingly dense vegetation — wet, mossy, and very different from what's outside. Back on the rim, the views extend in all directions: the island of Saba to the northwest, St Kitts and Nevis to the south, St Maarten on a clear day. Quill/Boven National Park manages the trails and charges a small entrance fee.
