Imagine swimming through shoals of colorful surgeonfish as you glide along the coral reefs of Hawaii in search of adventure. Sunbeams penetrate the ocean’s surface, cascading down to show off the submerged lava flows in an otherworldly glow.

Snorkeling tours on the Big Island take you on a journey beneath the waves, to a realm where wonders never cease. Feeling a little daring? Then a night snorkel with manta rays will be right up your street.

Here's everything you should to know about booking snorkeling tours, one of the most incredible outdoor activities on the Big Island.

What are the best snorkeling tours on the Big Island?

Small group snorkeling and dolphin tours on the Big Island

These Big Island snorkel excursions take place on sailing boats and catamarans for a relaxed and intimate experience. You’ll be adventuring with other travelers, but group sizes are kept small to minimize the impact on the environment and its inhabitants.

You’ll sail along the coast, admiring the scenery and soaking up the sun on deck. Keep your eyes peeled for dolphins and whales, which are often spotted during these trips.

On arrival in the marine reserve, it’s time to jump in and see what lies down below. The waters here are pristine, so life on the reef is thriving, making sightings a piece of cake. If it’s your first time, the guides will be on hand to give you some instruction to help you feel confident using a snorkel.

Flotation noodles and viewfinder boards can be provided, and the instructors will take you on a snorkel tour of all the best spots. Some of the larger boats have a water slide for daring swimmers. Breakfast and a barbeque lunch are also included on the longer trips to keep your energy levels topped up.

Night manta ray snorkeling tours on the Big Island

For something a bit more out of the ordinary, why not go snorkeling at night? This is when the manta rays come out to play and encountering them after dusk offers many moments of magic.

On these Big Island manta ray snorkeling tours, you’ll set sail after dark – the boat will be small to ensure a non-intrusive encounter. Then you’ll float in the water alongside the rays while holding onto the light board which illuminates the ocean. Your guide will be there to answer questions and keep everyone safe.

This is one of the most iconic experiences in Hawaii and a must for wildlife lovers and adventure seekers. You’ll see the rays gracefully gliding through the water as they come to feed on the plankton, which are attracted by the lights. You have nothing to fear from these gentle giants as they come up close to interact with each other.

Previous snorkeling experience is required for this excursion.

Private snorkeling trips on the Big Island

If you don’t fancy snorkeling in a group or just want to feel like a VIP, then private Big Island snorkeling tours are the answer.

The itineraries are the same as for the group tours, but you won’t be sharing your experience with anyone else. Your guide will select the perfect swimming spot away from the crowds, so it’ll be just you and the marine creatures you’ve come to see.

Both daytime and evening manta ray experiences can be booked as a private tour. Some trips take place on board a speed boat so you can reach the snorkel sites even faster. The route and activities can be tailored to your preferences.

Lunch is offered during day tours, while on night excursions, hot drinks are provided so you can warm up after your dip.

What if there are no manta ray sightings on the night tour?

Although manta rays are seen on most night snorkel tours on the Big Island, their presence isn’t guaranteed. They are wild animals after all.

If they fail to show up during your excursion, you will have the opportunity to rebook for free, depending on availability.

What happens in case of bad weather?

If your Big Island snorkeling excursion is canceled due to bad weather, don’t worry. You’ll be given a full refund or offered an alternative date. As such, it’s a good idea to book your tour at the start of your trip, just in case it has to be postponed.
