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.

Coming down the trail the view of Jacks is awesome, beautiful beach and the water had so many variations of blues and greens – emeralds, teals, blue, sapphire, dark and light – gorgeous. The beach and surrounding area is undeveloped, part of a protected area, very scenic. The shore is sandy with a lot of dried sea grass. The tree line didn’t provide much shade as its short bush. There is a rock ledge running from one end to about the middle of the beach (lots of urchins) making entry difficult to not possible. Mid-beach it was less rocky but still somewhat of a ledge basically around to the other side. Lots of sea grass in the water throughout the entire bay. The water was calm but not all that clear because of the seagrass - clearer in some spots than others. Nice for a hike, hanging out on the beach, enjoying the solitude and great view.

Hiking Tips

  • Tell someone where you are going and when you will return. Avoid hiking or swimming alone.
  • Allow for sufficient time to explore, swim and rest.
  • Remain on park trails – some trails cross private property, do not trespass into private property.
  • Wear cool clothing, comfortable walking shoes. Sandals are not recommended. Sneakers are your best option.
  • Protect yourself against the sun and insects.
  • Bring water and snacks.
  • Do not leave items or garbage on the trails. Make sure you leave with all the items you brought with you.
  • Do not remove anything from the park property; this includes but is not limited to shells, rocks, artifacts, flowers, plants and animals.
  • Pace yourself to prevent fatigue. Watch footing on wet rocks and trails made rough and slippery at times by heavy rainfall.
  • Do not eat unknown fruits, nuts or berries. Some plants and fruits are poisonous and can cause allergic reactions. Do not touch unfamiliar plants. Avoid handling or picking plant life that may harbor stinging insects, cause rashes, scratches or skin punctures. Many plants have thorns beware, look but don’t touch. Some ground covering shrubs cause severe itching – it is in your best interest to stay on trails.
  • Do not climb on fragile historic structures. Leave artifacts in place.
  • Hike early and return early.
