Big Island 4-Day Itinerary: Volcanoes to Kohala
Two Sides, One Island, Four Days
The Big Island of Hawaii is larger than all the other Hawaiian islands combined, and it contains eleven of the world's thirteen climate zones. A four-day itinerary has to make a choice: pick a side, or split the time and drive the full loop. This itinerary does both — two days exploring the dramatic volcanic south and east, two days on the sun-baked Kohala Coast in the northwest.
Day 1: Hilo and the East Side
Fly into Hilo International Airport (ITO). Hilo is wetter, cooler, and far less touristy than Kona. Check in, then walk downtown to Hilo Farmers Market on Mamo Street for tropical fruit, fresh poke, and an overwhelming variety of orchids. In the afternoon drive north on Highway 19 to Akaka Falls State Park — a five-minute loop trail leads to an 442-foot waterfall, one of the tallest in Hawaii. Dinner at Puka Puka Kitchen on Keawe Street. Sleep in Hilo.
Day 2: Hawaii Volcanoes National Park
This is the reason many people fly to the Big Island. Leave Hilo by 8 a.m. and drive 45 minutes to the park entrance on Highway 11. Stop first at the Kilauea Visitor Center to check the daily eruption status — activity changes week to week. Walk the Kilauea Iki Trail, a four-mile loop that descends through a rainforest and crosses the hardened lava floor of a crater that erupted in 1959. Drive the Chain of Craters Road down to the coast, where ancient petroglyphs and lava fields meet the ocean at Holei Sea Arch. If Kilauea is erupting, return to the park at dusk for the glow — the red light from the lava lake is visible from the Kilauea Overlook and Jaggar Museum area. Stay until dark, then drive back to Hilo.
Day 3: Drive the Saddle, Arrive Kohala
Check out of Hilo and drive Saddle Road (Highway 200) across the island. The road cuts between Mauna Kea and Mauna Loa at 6,000 feet elevation — bring a layer because temperatures drop fast. Stop at the Mauna Kea Access Road visitor station at 9,200 feet even if you are not going to the summit; the views across the island are extraordinary. Drop down the western slope into Waimea (Kamuela), stop at Village Burger for lunch, then continue to your Kohala Coast accommodation. Check into one of the resort strip hotels between Waikoloa and Mauna Kea Beach — the Four Seasons, Fairmont Orchid, and Mauna Lani anchor this stretch. Spend the evening at Anaehoomalu Bay (A-Bay), a calm, clear lagoon that is free and open to the public despite being flanked by resort property.
Day 4: Kohala Coast and Pu'ukohola Heiau
Morning snorkel at Two Step (Honaunau) if you are willing to drive 45 minutes south, or stay local and snorkel Kauna'oa (Mauna Kea Beach) — one of the few resort beaches with genuinely excellent snorkeling. Mid-morning drive north on Akoni Pule Highway to Pololu Valley Lookout at the end of the road. The valley view rivals Na Pali on Kauai. Stop at Pu'ukohola Heiau National Historic Site on the way back — the largest heiau (temple) in Hawaii sits on the coast and carries a charged history. Lunch at Kawaihae Harbor. Fly out of Kona Airport (KOA), 20 minutes south of Waikoloa.
Big Island Planning Notes
- Vog: Volcanic smog from Kilauea drifts to the Kona side when trade winds slow. Check weather.gov/hnl for the AQI forecast before booking outdoor activities on the leeward coast. The windward (Hilo) side is generally cleaner air.
- Two airports: Flying into Hilo (ITO) and out of Kona (KOA) eliminates backtracking and is often the same price. Check both airports when booking.
- Distances: Hilo to Kona via South Point is 125 miles and takes about 2.5 hours. Via Saddle Road it is 95 miles and 1.75 hours. Plan accordingly — the Big Island is not like Maui where everything is an hour away.
- Eruption status: Check nps.gov/havo before your trip. Kilauea has been intermittently erupting since 2021, but activity pauses without notice.
