Isaac Bay is long, mostly sandy. The far right is rocky with some sand and sandstone. Short shrubs line the shoreline; they provide little to no shade. The waters are mostly calm with the exception of the rocky area on the right and it deepens quickly. The bay is framed by beautiful, undeveloped hills.
Located on the far eastern end of St. Croix are Jack and Isaac Bays. They include 301-acres (122-hectares) of white sand beaches and upland forests and make up one of the few pristine ecosystems remaining on St. Croix. They are perfect for those looking for an off the beaten track beach. Jack and Issac Bays are accessible by hiking only and are often sparsely populated to unpopulated.
Snorkeling is excellent in the area. Coral reefs in these bays are home to at least 400 species of fish, including parrot fish, blue tangs, four-eyed butterfly fish and sergeant majors. These beaches have the largest nesting populations of green and hawksbill turtles on St. Croix and are under the care of the Nature Conservancy. Beach access may be limited during some periods of turtle nesting season. The Conservancy invites visitors to study turtle behavior and the landscape around Jack and Isaac Bays during guided hikes they conduct in an effort to educate visitors and collect funds to support their turtle monitoring and protection programs. Trails start at Point Udall down past East End Bay; behind the large satellite across from Cramer’s Park and up past Goat Hill and from the far left of Grapetree Bay.
