Best Things to Do in Kona, Hawaii — 2026 Activity Guide
Kailua-Kona concentrates more per-square-mile activity value than anywhere else on the Big Island. The dry west coast means conditions are reliable, tours run year-round, and the harbor at Honokohau puts you within 20 minutes of some of the best marine experiences in the state. Here's what's worth your time.
Snorkeling at Kealakekua Bay — The Best in the State
Kealakekua Bay is a State Marine Life Conservation District 12 miles south of Kailua-Kona. The Captain Cook Monument marks the spot where James Cook was killed in 1779. The snorkeling here — 80-foot visibility on a clear day, coral walls dropping 40 feet, spinner dolphins that rest in the bay most mornings — is the finest accessible snorkeling in Hawaii.
Getting there: You can't drive to the monument. Three options:
- Snorkel cruise (recommended) — Fair Wind, Body Glove, and Capt. Cook Snorkeling Tours run daily morning and afternoon trips from Keauhou or Honokohau Harbor. 2–4 hours on the water, gear included, $80–120/person.
- Kayak — rent from Napoopoo Beach and paddle 1 mile across the bay. Kayak companies in Kailua-Kona rent equipment and provide the permit. About 2 hours round-trip.
- Hike — 2.2 miles down a steep trail with 1,400-foot elevation change. Strenuous both ways. Permit required (free, limited). Most people take the boat.
What you'll see: Dense schools of fish, sea turtles, moray eels, octopus, and spinner dolphins. On calm days, dolphins rest in the bay until 11 AM before heading offshore to feed — snorkeling among them before they leave is legal (maintain 50-yard distance) and common.
Manta Ray Night Snorkel — Kona's Signature Experience
Two sites off the Kona coast — Manta Village (near Keauhou) and Manta Heaven (near the airport) — have the highest manta ray encounter rate in Hawaii: approximately 96% sighting success on clear-water nights. Manta rays at these sites are attracted by plankton that congregates around dive boat lights. The rays fly in slow circles, sometimes passing within inches of snorkelers.
How it works: Tour boats anchor, drop an underwater light, and snorkelers hang on a board or dive floats at the surface watching rays circle below. No certification required for snorkeling. Divers go to the bottom (20–25 feet) for a closer view.
When: Year-round, nightly. Best conditions are calm nights with minimal surge.
Duration: 2 hours on the water, typically 7:00–9:00 PM.
Book ahead: Manta tours sell out. Peak season (June–September) books 1–2 weeks out. Same-day availability is rare.
Kona Coffee Farm Tours
The Kona Coffee Belt is a 30-mile strip of farm country on the slopes above the coast between Holualoa (north) and Honaunau (south). The volcanic soil, afternoon cloud cover, and mild temperatures create conditions that coffee agronomists describe as near-perfect for Arabica. The "Kona" appellation requires 100% Kona-grown beans — the most geographically restricted coffee appellation in the U.S.
What a farm tour includes: Most farms offer 30–60-minute walks through the growing area, covering the cherry-to-bean process: picking, pulping, fermenting, drying, hulling, roasting. Tasting comparison of different roast levels and processing methods. Many tours are free.
Recommended farms:
- Greenwell Farms — One of the oldest Kona operations (est. 1850), free tours, excellent intro to the appellation. In Kealakekua.
- Mountain Thunder — Organic certified, good tour for seeing the roasting process. Near Kailua-Kona.
- UCC Hawaii — Japanese-owned, professional setup, strong on processing explanation. Near Kealakekua.
Tip: Don't buy coffee at ABC Store or airport. The legal minimum for a product labeled "Kona blend" is only 10% Kona beans. Buy direct from farms for 100% Kona at comparable prices.
Kahaluʻu Beach Park — Best In-Town Snorkel
Most Big Island beaches require driving to the Kohala Coast or heading south toward Punaluʻu. Kahaluʻu Beach Park is the exception: a pocket reef 2 miles south of Kailua-Kona town with a consistent sea turtle population, calm protected water, and a sandy entry point.
What you'll find: Hawaiian green sea turtles (honu) feed on the algae growing on the reef and rest on the rocks. Fish density is high — parrotfish, triggerfish, tangs in numbers. Water is shallow enough for beginners (3–10 feet over the reef).
Practical: Free parking lot (fills by 9 AM). Snorkel rental stand at the beach. Showers, restrooms, lifeguard during park hours.
Whale Watching (December–April)
All commercial whale watching tours on the Big Island depart from Honokohau Harbor, 2 miles north of Kailua-Kona. Humpback whales arrive in Hawaiian waters from Alaska in December and stay through April, with peak activity February–March.
What to expect: 2-hour tours, $60–90/person. Sighting guaranteed on most tours during peak season. Breach rates in the Au'au Channel (Maui side) are higher statistically, but Kona tours still regularly see surface behavior — breaching, pec slapping, spy-hopping.
Bonus: From December–April, snorkelers at any Kona water-sports site sometimes hear whale song underwater — one of the stranger and more memorable experiences in Hawaii.
Sunset Cruise from Honokohau Harbor
Several operators run 2–3-hour sunset sails and catamarans from Honokohau Harbor. The Kona coast at dusk — sun dropping over open ocean to the west, Mauna Kea silhouetted behind you — is reliably spectacular.
Options: Fair Wind and Body Glove run the most established boats. Both include snorkeling stops, food, and open bar. Expect 30–50 passengers on larger catamarans. Smaller operators offer private charters.
Puʻuhonua o Hōnaunau — Place of Refuge
One of the most significant cultural sites in the state, 20 miles south of Kailua-Kona. A National Historical Park, no admission fee. A puʻuhonua (place of refuge) was where kapu (law) breakers could seek sanctuary in ancient Hawaii — reaching it before being caught meant absolution.
The park: Royal fishponds, reconstructed temple (heiau), carved wooden kī'i (deity figures), and a well-preserved stone wall enclosure on the ocean. The site is beautifully preserved and genuinely moving.
Snorkeling: The Two-Step entry point (a natural lava step into the ocean) adjacent to the park has excellent snorkeling — sea turtles, reef fish, and spinner dolphins in the bay. No facilities, just a gravel pull-off. One of the best snorkel spots in the Kona district.
Day Trips from Kona
Hawaiʻi Volcanoes National Park: 1.5 hours south on HI-11. Long enough for a half-day visit; most travelers combine it with a night in Hilo rather than driving back to Kona the same day. Volcano night viewing guide →
South Point (Ka Lae): The southernmost point in the United States, 2.5 hours south of Kona. The green sand beach (Papakolea) is 2.5 miles each way over rough lava — rent a truck bed ride at the parking area rather than walking in heat. Genuinely green sand from olivine crystals eroded from cinder cones. Small cliffs for jumping into deep blue water.
Mauna Kea summit: 1 hour from Kona to the Visitor Information Station via Saddle Road. Add 30 minutes for the summit road. For sunset and stargazing, leave Kona around 3 PM. Perseid viewing guide →
Kona Logistics
Where to stay: Ali'i Drive puts you walking distance of restaurants and the harbor. The Kohala Coast resorts (30 minutes north) offer resort beaches but require driving for everything. Budget options cluster in central Kailua-Kona town off Kuakini Highway.
Car: Essential. Kona has no meaningful public transit for visitors. Rent at Kona International Airport (KOA) — off-airport agencies on Kuakini Highway are 20–30% cheaper.
Parking: Limited on Ali'i Drive. The Kona Inn Shopping Village lot charges $1/hour. Kahaluʻu Beach fills by 9 AM in peak season.
