The core of this tour is the dolphin cruise, which lasts approximately 50 minutes. You’ll board a sporty cruiser, greeted with refreshing mango juice — a nice touch that immediately sets a laid-back tone. The boat ride is smooth, and the crew is known for being friendly and knowledgeable.
What makes this segment special is the opportunity to spot skipjack tuna and flying fish, which are often seen skimming the sea surface. But the real highlight? Watching spinner dolphins leap and twirl in tropical waters.

The bus takes you back to the Fish Eye Visitor Center, then across to the observatory at Piti Bay. Walking the ocean bridge offers breathtaking reef views as you cross over the waves.
Descending 72 steps to the lower deck places you about 10 meters underwater, with 26 panoramic windows revealing more than 200 species of tropical fish and 80 varieties of colorful coral. From this vantage point, you can observe marine life in its natural habitat, making it a truly immersive experience.
Guests have described the observatory as a highlight, with one noting, “The views through those giant windows are stunning, and you get a real sense of what’s happening beneath the surface.” The setup is ideal for those who want a close-up look at coral reefs and marine species without getting wet.
