Big Island Snorkeling Tours: Common Questions

What happens on a manta night snorkel?

You board in the late afternoon or evening, ride out to a manta viewing site off the Kona coast, and float at the surface holding a board while underwater lights draw plankton up and the mantas feed below. Ten tours in this comparison offer that experience.

Which month should you snorkel the Big Island?

Every tour on this page runs year round. Manta sightings happen in all months, Kealakekua Bay is a steady destination, and winter adds whale watching trips from $99.

Do you need to be a strong swimmer?

Many first-time snorkelers join these tours, and several catamaran and raft operators run family-friendly departures. Operators supply masks, fins and flotation, and brief everyone before entering the water.

Why do boats go to Kealakekua Bay?

The bay holds some of the clearest water and healthiest coral on the Kona coast, and the Captain Cook Monument at Ka'awaloa is reached by boat or a long hike, which is why so many tours anchor there. Eleven trips in this comparison include it, from $80 per person, lasting three to four and a half hours.

Is snorkel equipment provided?

Yes on almost every trip. Masks, fins and snorkels are standard inclusions on these tours, and one small-group manta outing lists a wetsuit right in its title.

Do the tours offer free cancellation?

All 31 tours compared here come with free cancellation. Each operator sets its own cutoff, and the exact window is shown on the live booking page when you reserve.
