Discover vibrant coral reefs and marine life on this 4.5-hour Kona snorkeling tour with expert guides, comfortable boat, and authentic Hawaiian scenery.
Planning a trip to the Big Island of Hawaii and looking for a way to experience its stunning marine environment? The Kona Snorkeling Adventure Open Charter offers an inviting way to explore beneath the waves, with a focus on vibrant coral reefs, diverse marine life, and scenic coastline. While it’s a relatively short trip—about four and a half hours—it packs a punch in terms of memorable sights and knowledgeable guidance.
Two things we love about this tour are the expert crew’s lively commentary—which makes the whole experience educational and fun—and the comfortable, well-equipped boat that ensures a smooth ride. The only potential drawback is that, at $160 per person, it’s not the cheapest activity on the island, but you get quite a bit of value in return. This tour is ideal for travelers who want a relaxed, well-organized snorkeling outing with a small group atmosphere and a chance to learn about the region’s marine environment.
If you’re someone who appreciates expert guides, beautiful scenery, and the chance to see turtles and colorful fish in their natural habitat, this could be a great fit. It’s also suitable for those with moderate physical fitness—since snorkelers will need to swim a bit—but no previous experience is required.

The Kona Snorkeling Adventure departs at 7:30 a.m. from Manta Adventures a convenient location in Kailua-Kona. The tour spends about four and a half hours exploring the Kona Coast, offering plenty of time to enjoy the scenery and underwater sights without feeling rushed.
The vessel, a 36-foot custom-made Island Hopper, is designed for comfort and stability, making the sea crossing pleasant even if the weather isn’t perfectly calm. The boat has onboard restrooms and a warm water shower—small touches that make a difference when you’re spending several hours on the water.
The trip’s main draw is the chance to see vibrant coral reefs teeming with life. Guides will lead you to the best snorkeling spots, where you can glide through crystal-clear waters, marvel at the kaleidoscope of colors, and encounter fascinating marine creatures. The tour highlights encounters with sea turtles, schools of colorful fish such as parrotfish and butterflyfish, and curious clownfish darting through anemones.
The tour also comes with all snorkeling equipment—masks, fins, and snorkels—meaning you won’t need to rent gear elsewhere. Bottled water and snacks are provided, so you can stay hydrated and energized during your underwater adventure.
