This dive site, Isabella Reef, is named after a small wreck nestled among its coral formations. Situated off the coast of Sint Maarten, the site offers a maximum recreational depth of 22 meters, with an average dive profile often around 11 meters. While the main coral reef structures are described as being present from 22 to 29 meters, divers primarily explore the shallower reaches down to 22 meters, which are rich with vibrant barrel sponges and various corals. The wreck serves as an excellent focal point and provides an artificial reef habitat, making navigation engaging and rewarding.
Divers can expect to encounter a variety of marine animals, including schools of jacks, the impressive gray shark, and the graceful hawksbill turtle. The reef's structure of barrel sponges and different corals also supports a rich ecosystem of smaller reef fish and invertebrates, contributing to a lively and colorful underwater scene.
Isabella Reef is particularly popular for Deep Diving training due to its depth profile. The best time to visit for optimal conditions generally aligns with Sint Maarten's dry season, typically from December to May, offering calmer seas and excellent visibility. While primarily a scuba diving site, experienced freedivers might find the 22-meter depth appealing for practice, though the primary reef features are deeper.
