St Croix, part of the US Virgin Islands, offers some of the Caribbean’s best snorkeling, thanks to its calm waters, clear visibility, and an abundance of marine life. Whether you’re a novice or an experienced snorkeler, the island provides options that suit different preferences and interests. We’re particularly fond of the Snorkeling with Sea Turtles at Rainbow Beach because it combines relaxing beach activities with the chance to swim alongside turtles and other sea creatures. The inclusive water sports rental and friendly hosts make it an easy choice for a fun day on the water. For a more guided experience focused solely on turtle encounters, the Frederiksted Sea Turtles Snorkeling Tour offers an intimate look at Hawksbill and Green Sea Turtles in their natural habitat. Both tours promise unforgettable underwater moments, but each caters to different needs.
Quick Overview
This list features two top-rated snorkeling tours in St Croix. The first combines a relaxed beach day with full access to kayaks, paddleboards, and snorkeling gear at Rainbow Beach, ideal for those who want flexibility and a casual atmosphere. The second is a guided, focused turtle snorkeling tour that immerses you in the waters where Hawksbill and Green Sea Turtles are most often seen. Both options have received excellent reviews for their friendly guides, memorable encounters, and overall value. Now, let’s explore each in detail.
1. Snorkeling with Sea Turtles

At number one on our list is the Snorkeling with Sea Turtles experience at Rainbow Beach, which offers a blend of beach relaxation and water-based fun. This package includes full day beach gear rental, so you can keep your swimwear on and enjoy the water all day long. Unlimited access to kayaks, paddle-boards, snorkel gear, and beach floats makes this a versatile choice for those who want to explore at their own pace. The calm waters surrounding Rainbow Beach are perfect for beginners or families with children, and the nearby restaurants provide a convenient way to grab a bite or cool drinks.
What sets this tour apart is the atmosphere. The hosts—friendly and helpful—make everyone feel comfortable, whether you’re trying snorkeling for the first time or just want to unwind. Many reviewers praise the experience for its ease and the chance to see sea turtles, rays, barracuda, and numerous fish, often described as “mild and easy to swim in.” Brandon and Joe, the tour operators, are especially noted for their warm hospitality and caring attitude, making you feel like you’re snorkeling with friends rather than strangers. The accessibility and relaxed vibe make this suitable for all ages and skill levels.
Bottom Line: If you want a flexible, all-day water adventure with the chance to see turtles and marine life while relaxing on Rainbow Beach, this tour provides great value and a friendly atmosphere.
2. The Frederiksted St. Croix Sea Turtles Snorkeling Tour

For those more interested in a guided experience, the Frederiksted Sea Turtles Snorkeling Tour offers a focused outing that emphasizes swimming with Hawksbill and Green Sea Turtles in clear, shallow waters. This tour lasts about 1 hour and 15 minutes, making it a shorter but highly concentrated adventure. It includes expert guidance and all necessary snorkeling gear, ensuring you can focus on the experience without worrying about equipment.
The tour is designed to maximize your chances of encountering turtles without disturbing their natural setting. A reviewer described it as “an amazing experience” with the guide Jovan prioritizing safety while helping maximize encounters with marine life. The shallow waters make it accessible for snorkelers of all skill levels, and the small group setting allows for personalized attention. The cost, at $89 per person, reflects its guided nature and specialized focus.
Bottom Line: This guided tour is perfect if you want a more intimate, structured encounter with sea turtles, especially if you’re short on time but want a high-quality experience.
How to Choose
When deciding between these two options, consider your budget, time constraints, and what kind of experience you’re after. The Rainbow Beach tour is ideal if you want the freedom to explore the water at your own pace and enjoy other beach activities, making it great for families or casual water lovers. The guided Sea Turtles Tour suits travelers who prefer expert guidance and a higher chance of close-up turtle encounters in a shorter time frame.
If seeing turtles is your main goal, both tours deliver, but the guided tour offers a more focused, intimate experience, while the Rainbow Beach option provides a full day of relaxed fun with multiple water activities. For a broader adventure with flexibility, check out the snorkeling with sea turtles experience.
Final Thoughts
St Croix truly caters to snorkelers at every level. For those seeking a laid-back day with opportunities to see sea turtles and other marine creatures, the Rainbow Beach package is hard to beat. If you prefer a guided, small-group experience focused solely on turtle encounters, the Frederiksted tour offers a more personal journey.
Both tours are highly rated and provide memorable experiences. To ensure you don’t miss out, consider booking early, especially during peak season. Whichever you choose, remember that snorkeling in St Croix is a chance to connect with the sea in a way that’s both relaxing and awe-inspiring. Happy snorkeling!
