St Johns in Antigua and Barbuda offers some of the Caribbean’s most inviting waters and islands. The boat tours here stand out because they combine spectacular scenery with authentic experiences, often away from the busy cruise ship crowds. We especially like the Green Island and Sea Turtles Half Day Trip for its personal touch and the chance to see wildlife up close. Meanwhile, the Private Catamaran Charter is perfect if you want a tailored experience, especially for families or groups wanting privacy and flexibility.
Whether you’re looking for a quick, relaxed island visit or a full day on the water with snorkeling and lunch, St Johns has options. The list below highlights two of the best boat tours, each offering distinct ways to explore Antigua’s waters.

Both tours are highly rated and offer unique vantage points of Antigua’s beautiful coastline. Now, let’s dive into each one in detail.
1. FANTASTIC Green Island and Sea Turtles – Half Day share boat trip
At number one on our list is the Green Island and Sea Turtles Half Day Trip. For around $180 per person, this tour offers a quiet, personal experience on Green Island, a pristine, government-protected island known for its untouched beauty. The trip begins with a van transfer from St Johns or your resort to Willikies, where the boat departs.
What makes this tour special is the small group size—just seven people—giving you a chance to relax without the noise and crowds of larger boats. The highlight is spending about 3 hours on Green Island, where you can lounge on the beach, explore the shoreline, and enjoy crystal-clear waters. The island is renowned for its rich marine life, including frequent turtle sightings, which add a magical touch to the experience. Afterward, the trip includes a transfer back to St Johns, completing a smooth, hassle-free adventure.
Guests consistently mention how private and peaceful this tour is, with reviews praising the personalized service, fresh fruit, and the chance to see turtles. One visitor summed it up: “Very private. They made sure we got to see turtles and had a pleasant trip.” This tour is ideal for travelers wanting an authentic, relaxed day away from crowds, especially if you appreciate nature and wildlife.
Bottom Line: If you prioritize intimacy, wildlife encounters, and a serene beach experience, this half-day tour is hard to beat.
2. Catamaran private charter
Next, at number two, is the Catamaran Private Charter. Priced at $1,800 per group (up to 15 people), this experience offers a fully customizable day on Antigua’s waters. Whether you want a half-day, full-day, or sunset cruise, this private charter adapts to your group’s preferences.
The captain and crew focus on providing personalized service, with no need to bring your own snorkeling gear—everything is provided. The tour can include snorkeling over coral reefs, swimming in calm bays, or simply relaxing on deck while enjoying the views. A highlight is the stop at a local restaurant for lunch, allowing you to sample island cuisine without leaving the boat.
Guests praise Kareem, the guide, for his extensive island knowledge and genuine care for visitors. One reviewer notes, “He knows his island best and did all to show us more than he had to.” This tour is perfect for families, couples, or friends looking for an exclusive experience with flexibility and comfort. Because of its tailored nature, it’s an excellent choice for those wanting a private, stress-free day on the water.
Bottom Line: For groups seeking a flexible, all-inclusive day with snorkeling, lunch, and privacy, this private catamaran is a standout.
How to Choose
When deciding between these options, consider your budget, interests, and how much time you want to spend on the water. The Green Island trip offers a private, wildlife-focused outing perfect for those craving serenity and nature encounters without breaking the bank. It’s well-suited for travelers who prefer a small-group, relaxed experience.
On the other hand, the Private Catamaran Charter is ideal if your group values exclusivity, customized itineraries, or wants to combine snorkeling with a scenic lunch. It’s a bit pricier but offers the flexibility to craft your perfect day.
Booking early is recommended, especially for the private charter, to secure your preferred date and time. Also, think about your physical activity level—both tours involve some swimming or walking, but the private charter can design a more leisurely day.
