Top Water Activities in Kona — Explore Hawaii’s Ocean Paradise

Kona’s Ocean — A Playground of Wonder and Wellness

The Kona Coast is a living canvas of sunlight, coral, and deep blue water. Here, the Pacific is calm and clear, offering both excitement and serenity. Whether you’re snorkeling in coral gardens, sailing at sunset, or watching manta rays under the stars, the ocean becomes part of your story.

At Sea Paradise Hawaii, we’ve spent over 40 years guiding guests into this world — safely, sustainably, and with aloha. These are our favorite ways to experience Kona from the water.

The Best Ways to Enjoy the Ocean

Snorkeling at Kealakekua Bay

Start your day with our Morning Snorkel Tour — calm seas, clear visibility, and colorful reefs at legendary Kealakekua Bay. Glide above coral gardens alive with tropical fish and feel the warmth of the Hawaiian sun on your back.

Manta Ray Night Tours

Join our Manta Ray Night Tour for a once-in-a-lifetime adventure beneath the stars. Watch Kona’s graceful mantas loop and glide under the glow of blue light — a memory that will stay with you forever, backed by our Manta Guarantee.

Sailing into the Sunset

Even if you never enter the water, sailing aboard Hoku Nui is pure tranquility. Enjoy a beverage as the sun drops behind the horizon, painting the sky in gold and crimson on one of our sailing charters.

Kayaking & Paddleboarding

Kona’s bays are perfect for gentle exploration. Kayak through calm waters around Keauhou Bay or Holualoa, or rent a paddleboard for an early-morning glide when the sea feels like glass.

Scuba Diving & Free Diving

Certified divers can explore deeper coral structures and lava tubes offshore. Kona’s visibility often exceeds 100 feet — ideal for underwater photography, free diving, and manta observation.

Whale Watching (Seasonal)

From December to April, humpback whales (koholā) migrate through these waters. While Sea Paradise does not run dedicated whale tours, they’re often spotted on our daily sails. Learn more about the season on our Humpback Whale guide.

Responsible Recreation — Caring for the Sea You Enjoy

Choose Reef-Safe Products

Sunscreens with zinc oxide or titanium dioxide help protect both your skin and Kona’s fragile coral reef ecosystems.

Respect Wildlife

Keep at least 10 feet from turtles (honu), 50 yards from dolphins, and 100 yards from whales. Observe quietly and respectfully — admiration, not pursuit, helps protect these incredible animals.

Book Certified Eco-Tours

Choosing responsible operators like Sea Paradise supports reef-safe practices, conservation education, and sustainable ocean tourism — ensuring these waters remain healthy for generations to come.

Build Your Kona Adventure

Mix and match the perfect combination of exploration and relaxation:

That’s a full day of discovery, comfort, and connection to the ocean — all powered by aloha.

Excellent!
The crew were professional, kind, knowledgeable and fun.
Extremely clean, with luxury bathroom facilities.
Lots of refreshments and snacks, also a freshwater shower to wash off as you get out of the sea.

Awesome experience. This is the place to do a manta ray tour. We have done one before and in the other area where you see the manta rays. The short boat ride to the area is the way to go. Last time 30 mins ride. Koa boat captain and Eric the guide who was in the water with us was very knowledgeable and being in a smaller group is by far the way to go… if/when we make it back we will definitely book with Kona Mantas…

Seaquest did a phenomenal job for exploring The Big Island’s ocean. We did the night Manta Ray dive and the South Kona Expedition Snorkel tour. Such magical experiences. We saw nonstop Manta Rays. Even got several Manta Ray kisses. The South Kona Expedition Snorkel tour had 3 snorkel spots. Best snorkeling in all of the Islands Ive visited so far. The captains and guides are super friendly and knowledgeable. I know when I come back to the Big Island I will book from Seaquest again!

Had a great experience with the paradise crew and captain. They really go all out to make a memorable day out on the water. Today, a squall ran through halfway through the trip and we started heading back. But the conditions improved, and the boat resumed our snorkel trip after packing everything away. You can trust them. and a a great food spread too. Nice size boat and we never felt crowded. Choose these guys!

The catamaran snorkel tour was the highlight of our trip! Such a fun, friendly crew. One of the crew made mermaid bubbles in the water for my 6 year old niece. It was super cool! Our group of 13 enjoyed every minute of it.

These folks are the best! We did the Manta Ray night snorkel and then came back a couple days later for the Kealekekua Bay day snorkel catamaran. The team both times was super friendly, fun, knowledgeable and helpful. We had a blast, the boat was clean and comfortable, saw tons of amazing ocean life, and learned more about the beautiful creatures we share the world with and some interesting history about the area. Highly recommend Sea Paradise for anyone looking for a fantastic snorkeling experience.

Booked the night manta ray trip and it did NOT disappoint! We had SO many mantas under us as ALL times. There were about 11-12 different mantas swimming under us. The guides said they average about 3 a night so it was an extra special trip! Guides were super knowledgeable and #1 priority was the safety of the mantas and the guests. I get seasick VERY easily and I definitely was fighting it during the end of the trip but luckily less than a 5 min boat ride to and from the dock and they have ample ginger chews. This experience was truly a bucket list experience and Sea Paradise was a great company to do it with!!

We just got off the morning snorkeling trip and we had an amazing time. The entire crew was polite, professional and helpful in every way. They really made the trip fun and enjoyable. The boat was clean and well maintained with the cleanest bathrooms you will see on a charter boat. They had good snorkeling gear and the crew is right there ready to help you in any way you needed it to make sure you had a fun safe experience. Both the breakfast and lunch meals that come with the trip were delicious and beyond what I was expecting. The bartender can make some good drinks 🍹 for the ride home when the snorkeling is done.

One thing I did notice that Sea Paradise was doing that other boats around us weren’t doing. Sea Paradise puts crew members on paddle boards as lifeguards in the areas that you are swimming. That’s a big plus for safe in my eyes and I appreciate that.

Thank you again for the great time and great memories.

We enjoyed this morning snorkeling trip very much. The catamaran is nice (and it really does have the nicest bathrooms we've ever seen on a boat) and the crew is amazing. They're friendly, constantly offering food and drinks, and make sure everyone is well taken care of. They have everything you need for the trip, down to the reef safe sunscreen and hand sanitizer. The continental breakfast and coffee is nice in the morning, and we enjoyed the sandwich lunch after a couple of 45 minute snorkeling sessions. The snorkeling equipment is good and didn't leak like many do. The entire sail over and back is very pleasant. The snorkeling spots are fine, not the best we've seen, but had some decent fish. The drop off at Kealakekua Bay is cool to see. Overall, great experience well worth a morning.
