The Diving

While the entire Big Island has excellent diving, the dive sites on the Kona-Kohala cost has the best diving in Hawaii. Hawaii has almost 700 species of fish, and 25% of them are only found in Hawaii. Kona has a huge variety of dive sites, ranging from easy dives for beginners, to advanced, deeper dives for the more experienced.

The island is surrounded by a coral belt, and has plenty of sea caves to explore, along with abundant marine life. The diving conditions are better on the Kona side than the Hilo side, and it’s common to have a visibility of 30m (100ft).

The Lava Dome

The lava dome is a volcanic rock, and it’s covered in knob and plate coral. The dome stands around 30ft high, and schooling fish like to congregate here, as well as Blue Dragon Nudibranchs.

Big Sandies

Big Sandies is an ocean swimming pool, with white sand rivers at 20ft, surrounded by coral, along with octopus, shells, and other invertebrates. It’s a good dive for beginners, as the depth is only 15-70 ft, and there is plenty to see.

Garden Eels

Also great for beginners, this site is where divers will see rows garden eels swaying in the current, along with plenty of moray eels and turtles, There are a few swim-throughs here as well. This is where dive sites will often do Manta Ray diving at night, as they’re attracted to the underwater lights of the snorkelers and divers.

Alices Wonderland

There’s something at this site for all levels of diver, and the giant arches are home to healthy coral and many different types of marine life, including frog fish, octopus, schooling fish, and pelagic encounters. There’s also a steep drop off to explore outside of the mooring.

Golden Arches

This site has one of the best lava arches along the Kona Coast. Divers will find plenty of yellow reef fish, along with triggerfish, widemouth morays, rock mover wrasses, and occasionally leaf scorpionfish, frogfish, along with dolphins which sometimes visit the area.

Turtle Pinnacle and Turtle Heaven

Both of these dive sites are brilliant places to see green sea turtles, which like to relax on the reef while surgeonfish eat lunch off of their backs. Divers are also likely to see octopuses, spinner dolphins, and moray eels.


Honokahau is the place to go to see gorgeous, well-developed coral, and brightly coloured reef fish. Some of the residents at this site include goatfish, heller’s barracuda, eagle rays, raccoon butterflyfish, and occasionally spinner dolphins.

Kaiwi Point

Divers can only access this site by boat, but it’s well worth it. Trumpetfish, trevally, and triggerfish are always hanging around here, and there is also a huge lava rock wall known as “Wash Rock”, that rises from the bottom of the sea, along with a drop off where divers can often see sharks, manta rays, and sometimes humpback whales.

Suckem Up Lava Tube

This site is made up of large caverns, which divers can swim through, and be sucked out with the surge. One of them is known as “Skull Cave”, which has two eye sockets which ivers can swim through while keeping an eye out for white tip reef sharks, colourful reef fish, moray eels, and spiny lobsters.

How to Get there

Tourists can get to Kona via Kona International Airport, which is also known as Keyhole Airport. Domestic flights arrive from Honolulu and Kahului, as well as the West Coast of the United States, and Vancouver, Canada.

Most international flights will transfer via Honolulu. There is a Hele-on bus which operates from the airport into Kona once a day, but if flight times don’t match up with the bus, travellers will need to get a shuttle or taxi which range from $30-$50.

It can be a good idea to hire a car near the airport, as the island can be tricky to get around. Most locals hitchhike, which obviously isn’t ideal for those traveling with children. By hiring a car tourists can then travel around the whole island, and explore the numerous sights without having to arrange day tours.

Where to Eat & Drink

The food in Hawaii is as diverse as the population. Traditions have been brought in from around the world, and the food has been influenced by the United States, native Hawaiians, China, the Philippines, Japan, and Korea. Expect to find plenty of fresh fruit on the island, with mangos picked straight from the tree, and pineapple that melts in your mouth.

For dinner with a view of the ocean, head to Jameson’s which is great for a romantic meal or even dinner with the kids. Be sure to make reservations ahead of time though, and ask for a table on the Lanai so you can watch the sunset.

The Manta & Pavilion Wine Bar does a great breakfast buffet with made-to-order waffles and omelettes, delicious pastries, and fresh tropical fruits and juices.

Those who like beer should head to Humpy’s Alehouse, which has a huge array of beers on tap, and excellent bar food. It’s popular with both locals and visitors and gets loud at night.

The nightlife in Kona isn’t the kind that stays open until 4am with pounding base and laser lights, but Kona is the place to go for a wide selection of bars, live local bands, and a few beers after a long day of diving. Lulu’s is a good place for a cocktail, along with Cafe Pesto and the Hilo Bay Cafe.

Other Activities

Those who need a break from diving will be spoilt for choice, as the island offers plenty of activities to keep tourists occupied. Head to Huihe’e Palace, which was once the vacation residence of the Hawaiian royalty. This is a great place to learn more about the history of Hawaii, as well as enjoy the fascinating artefacts and beautiful furniture on display.

The Historic Kailua Village Walking tour is an excellent way to get to know Kailua, and visits the Huilhe’e palace, St Michaels Catholic Church, and Moku`aikaua Church.

The best snorkelling is found at the Captain Cook Monument, which is where Captain Cook was killed after returning to Hawaii. Tourists can either choose to take a kayak across to the area, or hike across. Be sure to bring plenty of water if hiking, and good shoes as the trail can be tough.     

Family Friendly

The Big Island is a very family-friendly destination, especially if the family likes to be active. Take the kids swimming with the dolphins, but before you book it, head over to Two Step first thing in the morning to see if you can swim with them in the wild. If all else fails, try a company like Dolphin Discoveries.

Those interested in seeing a 420ft waterfall that is constantly flowing year round should head to Akaka Falls State Park. Located on the Hilo side of the island (the east side), the park is free to enter and it takes less than an hour to walk along the was paved trail.

Family Activity can be a Seahorse farm visit! Credit

Don’t miss the Green Sand Beach (Papakolea Beach). While it can be tricky to get to it, there are guys with four wheel drives who can drive you down to the beach so you don’t need to hike with the kids. The sand is an olive-green colour, and the contrast between the green sand and blue water is breathtaking. Make sure you’re prepared for the trip though, as there are no food, or bathrooms here.

Take plenty of bug spray as the mosquitos are usually out in full force. Remember sunscreen and a hat, and plenty of water if you decide to do any of the many hikes around the island.
