Discover the Underwater World of Vanuatu with the Reef Explorer Semi-Submarine Tour

Imagine gliding above the vibrant coral reefs surrounding Iririki Island without getting your feet wet. That’s exactly what the Reef Explorer offers — a 1-hour semi-submersible boat ride that takes you beneath the waterline through four large viewing windows. For just $30.56 per person, you get a front-row seat to Vanuatu’s underwater beauty, all from the comfort of a well-designed glass-bottom boat.
What we love about this tour is its accessibility — no swimming skills needed, making it ideal for families, seniors, or anyone who prefers to stay dry. Plus, with small group sizes (a maximum of 12 travelers), you’re likely to experience a more intimate, relaxed atmosphere. Another highlight is the knowledgeable guides who make the experience engaging and informative.
One possible consideration is the weather — the visibility depends heavily on clear skies. A cloudy day might limit what you see below, though good weather is typically expected in Port Vila. This tour suits travelers who want a safe, low-effort way to witness vibrant marine life without the hassle of snorkeling or diving. It’s perfect for families, those with limited mobility, or anyone curious about the underwater environment of Vanuatu without getting wet.

What You’ll See Beneath the Surface
The underwater windows are the star of the show. Expect vibrant fish, coral formations, and possibly some larger marine creatures. One reviewer, Megan, noted that they “got to see a variety of different fish” and the children loved feeding them from the deck. However, it’s worth mentioning that cloudy weather can restrict visibility, as Megan pointed out, so it’s best to aim for a clear day.
