The Quill
This extinct, perfectly formed, 1,972-foot volcano has a primeval rainforest in its crater. Hike any of eight trails through woodlands filled with giant elephant ears, ferns, flowers, wild orchids, and fruit trees. If you're lucky, you'll glimpse the elusive, endangered Iguana delicatissima (a large—sometimes several feet long—greenish-gray lizard with spikes down its back). The volcanic cone rises 3 miles (5 km) south of Oranjestad on the main road. The tourist board or St. Eustatius National Parks will supply trail maps and help you arrange a guided hike, but you must purchase a $10 permit before setting out. Figure on two to four hours to hike the volcano. Bring sufficient water and snacks with you.
