I’ve been to the Kona Coast three times, and every visit I’ve done the manta ray night snorkel. Once is enough to understand why people describe it as the single best wildlife experience of their lives. You motor out after dark to a spot about a mile offshore from the Sheraton, put on a mask and snorkel, grab a light board, and float face-down on the surface. Underwater lights on the boards attract plankton. The plankton attracts the mantas. Within minutes, these 10-foot wingspanned animals are barrel-rolling just inches below you, their white bellies scooping mouthfuls of plankton in slow, balletic circles. They don’t sting, don’t bite, don’t care about you except as a light source. It’s completely safe and completely extraordinary.
Kona occupies the sunny, dry leeward side of the Big Island — the side protected from the trade winds and rain that keep Hilo green. Ali’i Drive, the main waterfront street in Kailua-Kona town, is a two-mile strip of restaurants, dive shops, and galleries fronting the Pacific, anchored by the historic Kailua Pier where the Ironman World Championship begins and ends every October. The town has a certain swagger about it — this is where the most demanding endurance athletes on Earth come to race, and the culture reflects that energy.
The Kona Coffee Belt runs up the slopes of Hualalai volcano above town on Highway 11. The microclimate here — morning sun, afternoon cloud cover, volcanic soil, moderate humidity — creates growing conditions that produce some of the world’s most prized coffee. Greenwell Farms offers the most established tour (free, with tastings), but I prefer spending time at the smaller roasters in Holualoa Village above town, where you can buy directly from the farmers who grew it. A pound of genuine estate-grown Kona coffee runs $40–60. The difference from what’s sold as “Kona blend” on the mainland (legally only 10% Kona) is immediate and profound.
Kealakekua Bay, 14 miles south on Highway 11, holds the best snorkeling on the Big Island. The bay is a marine sanctuary with 100-foot visibility and extraordinary concentrations of tropical fish, spinner dolphins that come through most mornings, and the Captain Cook monument on the north shore marking the spot where Cook was killed in 1779. Access is by tour boat ($90–120, includes breakfast and lunch) or the steep 2-mile trail — I recommend the boat for snorkel time and dolphin encounters.
The Arrival
KOA airport drops you into the driest, sunniest coast in Hawaii — lava fields to the north, coffee farms climbing the volcano above, and the bluest Pacific you've ever seen straight ahead.
Why Kona should be on your Big Island itinerary
The Big Island is the youngest, most geologically active landmass in the Hawaiian chain, and the Kona Coast is its most accessible face. Unlike Hilo’s rainforest character, Kona presents the island in its raw lava-and-sunshine form: black rock coastlines, clear blue water, and a sky that seems closer to the equator than anywhere else in the US.
The manta ray experience alone justifies the trip. No other place in Hawaii reliably produces this wildlife encounter — giant oceanic mantas feeding in illuminated water just offshore, approaching to within a few feet with total indifference to the humans watching. I’ve done it three times and would do it again tomorrow.
The Kohala Coast, 25–40 minutes north, adds another dimension: some of the best beaches in the state (Hapuna Beach is consistently ranked among the top in Hawaii), luxury resorts in archaeological landscape, and ancient Hawaiian petroglyphs and heiau. Drive the Queen Ka’ahumanu Highway north from Kona airport through the lava fields to experience this coastal corridor.
What To Explore
Coffee farms climbing the volcano, mantas circling in the dark, ancient temples at the water's edge, and the clearest snorkeling bay on the Big Island.
What should you do in Kona?
Manta Ray Night Snorkel — The signature Big Island experience. Boats depart from Kailua Pier after 5pm and return by 9pm. Float above illuminated water while giant mantas feed inches below you. Cost: $100–160/person. Book ahead — popular tours sell out weeks in advance.
Kona Coffee Belt Farm Tours — Greenwell Farms (free tours, multiple daily), Kona Joe Coffee, Mountain Thunder, and the artisan roasters of Holualoa Village. Drive Highway 11 south from town and explore the coffee country above. Best during harvest season (September–January) when the red cherries are being picked.
Kealakekua Bay Snorkel Cruise — Tour boat to the marine sanctuary bay. Crystal visibility, spinner dolphins, reef sharks, abundant fish. Captain Cook monument snorkel stop and a second reef. Fair Wind Cruises and Captain Zodiac both excellent. Cost: $90–120 with breakfast and lunch included.
Pu’uhonua o Honaunau (Place of Refuge) — 22 miles south. Ancient Hawaiian sanctuary with reconstructed heiau, carved ki’i, fishponds, and one of the most significant cultural sites in Hawaii. The oceanfront setting is stunning. $20/vehicle. Allow 2 hours.
Hapuna Beach (Kohala Coast) — 30 minutes north. Consistently rated one of the best beaches in Hawaii. Half-mile of white sand, calm summer water, and fewer crowds than Kona town beaches. Free parking, public access.
Ali’i Drive Waterfront — The heart of Kailua-Kona town. Walk the pier, watch for sea turtles at the jetty rocks, browse surf shops, find a sunset table at Huggo’s on the Rocks. The Ironman finish line is painted on the pier. Free to walk; restaurants from $15–55.
Deep-Sea Sportfishing — The Kona Coast is legendary for Pacific blue marlin, yellowfin tuna, and mahi-mahi. Charter boats depart from Honokohau Harbor. Half-day charters from $200–350/person. The waters off Kona hold the world record for blue marlin caught.
- Getting There: Fly into KOA — direct from many mainland cities. Rental car mandatory. The airport is 7 miles north of Kailua-Kona town. Book the car before the flight; rental inventory at KOA is limited.
- Best Time: March through June and September through October. Kona is sunny year-round, so weather rarely dictates timing. Avoid October race week (Ironman) unless you want to be part of the spectacle.
- Money: Mid-range: $250–400/day. Kailua-Kona town hotels/condos: $180–300/night. Kohala Coast resorts: $400–1,000+. The manta ray snorkel ($100–160) is the best value experience on the island by far.
- Don't Miss: Buy a pound of genuine single-estate Kona coffee directly from the farm. The difference from mainland "Kona blend" is immediate. Greenwell Farms gives free tours and tastings to orient your palate before buying.
- Avoid: Buying Kona coffee at airport gift shops or mainland stores labeled "Kona blend." Hawaiian law allows coffee labeled Kona blend to contain as little as 10% actual Kona coffee. Buy 100% Kona from the farms on Highway 11.
- Local Tip: The Two Step snorkel entry at Honaunau Bay (just north of Pu'uhonua o Honaunau) is free, accessed via the boat ramp, and has outstanding snorkeling with turtles, fish, and occasionally dolphins. No tour boat required. Bring your own gear or rent in Kailua-Kona before heading south.
The Food
Fresh fish straight from the dock, the world's most coveted coffee from farms above town, and a waterfront dining scene that makes the most of 300 days of sunshine per year.
Where should you eat in Kona?
- Da Poke Shack — Consistently ranked among the best poke in the state. Counter service, small space, unforgettable ahi. $15–22/bowl. Lines are real — arrive at 11am when they open.
- Umeke’s — Outstanding poke bowls with fresh daily catches. Multiple proteins, creative sauces. $14–20. Kailua-Kona’s other poke institution, beloved by locals.
- Jackie Rey’s Ohana Grill — Long-standing local favorite for fresh seafood and steaks at fair prices. Good service, reliable quality. $25–45 mains. Consistently packed.
- Huggo’s on the Rocks — Oceanfront cocktails and seafood with waves literally lapping the outdoor platform. The best sunset location in Kona. $25–45 mains.
- Kona Brewing Company — The original brewpub in an industrial district inland from Ali’i Drive. Excellent pizza and their Longboard Lager and Pipeline Porter. $14–22. More local than the waterfront spots.
- Sam Choy’s Kai Lanai — Generous island portions with harbor views. The big plates of Hawaiian comfort food at accessible prices. $20–35.
- Island Lava Java — Ali’i Drive cafe for excellent coffee (local beans), light breakfast, and the best casual morning perch on the waterfront. $8–16.
- Puainako Town Center Food Court — Where locals eat. Multiple plate lunch vendors, Japanese, Filipino, and Hawaiian options for under $12. No atmosphere; excellent food.
Where to Stay
From waterfront condos in Kailua-Kona town to coffee-country B&Bs above the farm belt to luxury beach resorts on the Kohala Coast — the Big Island's widest accommodation range.
Where should you stay in Kona?
Kailua-Kona Town ($180–320/night) — Hotels and condos within walking distance of Ali’i Drive. Courtyard King Kamehameha Kona Beach Hotel and Royal Kona Resort are the best-positioned properties. Condos through VRBO offer better value for longer stays.
Kohala Coast Resorts ($400–1,200/night) — The luxury tier: Mauna Lani, Fairmont Orchid, and Waikoloa Beach Marriott offer white-sand beaches and full resort amenities 25–40 minutes north. For a big-occasion splurge in Hawaii, this coast is exceptional.
Holualoa Inn ($280–420/night) — Boutique B&B in the coffee village above Kona with panoramic ocean views and farm surroundings. The most distinctive mid-range option in the area.
Budget ($35–120/night) — Kailua-Kona has a few hostels and budget guesthouses. The Kona Sugar Shack Hostel and similar properties offer dorm beds from $35. Limited options compared to Hilo’s hostel scene.
Before You Go
Kona requires a rental car, a manta ray reservation, and a plan for the coffee belt. Everything else reveals itself once you're there.
When is the best time to visit Kona?
Kona is the driest coast in Hawaii — it receives under 20 inches of rain per year in Kailua-Kona town, compared to Hilo’s 130+. This makes it genuinely year-round, with weather rarely being a factor in visit timing.
March through June and September through October offer the best combination of price, crowds, and conditions. These shoulder periods have lower accommodation rates and less crowding than peak summer and winter.
July through August is peak family travel with highest rates. The Kohala Coast beaches are at their calmest for swimming during these months.
October brings the Ironman World Championship — the most extraordinary sporting event you’re likely to witness, with 2,500 athletes completing 2.4 miles of swimming, 112 miles of cycling, and 26.2 miles of running in a single day. Hotels book 12–18 months ahead. If this interests you even as a spectator, plan years in advance.
Kona coffee harvest season (September–January) is the best time for farm tours — the red coffee cherries are on the trees and picking operations are active. The Kona Coffee Cultural Festival in November is the peak celebration.
The manta ray snorkel operates year-round — the mantas are resident, not migratory, making this the one Big Island activity that requires no seasonal timing. See all Big Island destinations for the full itinerary picture, or start planning your Hawaii trip.
