How the Tour Is Structured
The tour begins with a straightforward, boat-based entry—no stairs, no heavy equipment—making it accessible for all. The boat transports you from the meeting point in Onna Village to the snorkeling site near the Blue Cave. Here, the guides assist with flotation devices, providing a supportive environment for non-swimmers or nervous participants. You’ll explore the famous Blue Cave, where sunlight creates an enchanting blue glow in the water, illuminating schools of tropical fish and coral reefs.
Following the snorkeling, you’ll transfer to a different, calmer underwater site for the Sea Walk—an experience where you walk along the ocean floor while wearing a helmet that supplies air. The face and hair stay dry, which is a huge plus for those who dislike getting wet or just want a hassle-free underwater experience.
The Blue Cave Snorkeling Experience
The Blue Cave is a highlight—famous for its striking natural light. According to reviews, “the water was incredibly clear, and the guides were very patient,” making it a perfect introduction for first-timers. The guides offer step-by-step guidance, making sure everyone feels confident before entering the water.
Guests are often impressed by the colorful marine life and the sense of floating just beneath the sunlight-dappled surface. The experience is accessible even to those who are non-swimmers, thanks to flotation aids and attentive guides. You won’t be diving or swimming deep—just staying on the surface and enjoying the view.
The Sea Walk Experience
The Sea Walk diverges from snorkeling by offering a walk along the ocean floor without getting wet. Participants descend a ladder from the boat with instructor help, and with a helmet that enables natural breathing through the nose and mouth, exploring the seabed becomes effortless. Reviews mention how relaxing and easy this part of the tour is—“my face stayed dry the whole time, and I felt like I was walking on the ocean floor, not swimming.”
The location is chosen for its calm conditions and sandy seabed, which minimizes risk and discomfort. It’s the perfect way for non-swimmers or those with a bit of ocean anxiety to enjoy marine life close-up.
