This dive site, Alien Nation, is a vibrant reef experience located off the coast of St. Croix in the US Virgin Islands. The dive typically begins at a mooring line situated at a depth of 14 meters (45 feet). From this point, the reef gently slopes westward, eventually meeting a sandy bottom at 28 meters (90 feet). The optimal diving depth, often referred to as the 'sweet spot,' lies between 15-20 meters (50-70 feet), where the reef's most captivating features are concentrated. While no specific historical narratives are provided for the site, its evocative name suggests a uniquely compelling underwater environment.
Divers at Alien Nation can anticipate a rich display of marine life and striking coral formations. The reef is characterized by the presence of large barrel sponges, providing habitat and visual interest. Numerous nooks and crevices offer ideal hiding places for various species of eels. Regular encounters include green sea turtles, which are frequently observed passing through the area en route to Sandy Point, and graceful stingrays often found resting along the sand line at approximately 12 meters (40 feet).
The dive site is generally accessible and enjoyable year-round, benefiting from the consistently favorable conditions of the Caribbean Sea. Its gentle topography and moderate depths make it an excellent choice for a wide range of divers, from beginners completing their open water certification to more experienced divers. Freedivers will also find the site particularly appealing, with its 'sweet spot' depths well within reach for extended exploration of the reef's vibrant ecosystems and animal encounters.
