The Big Island is the largest of the Hawaiian Islands and the youngest in the chain. Five volcanoes built it, and Kīlauea and Mauna Loa are still active. Most trips split between Kona, on the dry west coast, with its beaches and coffee farms, and Hilo, on the wet east side, close to rain forest, waterfalls and Hawaiʻi Volcanoes National Park.
A week to ten days gives you time for both coasts and the volcanoes without rushing. Distances are long, so plan on a rental car. Mauna Kea's summit is high and cold, so bring warm layers for sunset and stargazing. Kona is usually driest from about April through October, while Hilo gets rain year-round. Volcanic activity changes, so check the national park's current status before you plan around the crater.
Big Island in five
- Rent a car before you landBeaches, trailheads and towns are long drives apart, and the Hele-On bus does not reach every route. Book the car early for high season.Getting around
- Check your rental contract for Mauna KeaThe upper summit road needs four-wheel drive, and many rental agreements forbid driving it. Read that clause before you leave the lot.
- Get a pass for Hawaiʻi Volcanoes National ParkThe park charges a fee per vehicle, so one paid car covers everyone in it. Check nps.gov/havo for current fees and reservation rules before you drive up.
- Pack sunscreen without oxybenzone or octinoxateHawaii law bans the sale of sunscreens with these two ingredients, but it does not stop you from bringing your own. Read the label before you swim.
- Set up a rain plan for HiloHilo and the east side get far more rain than Kona. Save the rain forest and waterfalls for wet days and the beaches for dry ones.

How many days do you need on the Big Island?
Four to five days covers Kona, the volcano park and one day on the Hilo side. Add days if you want the Kohala Coast or Waipio Valley, since the drives are long.
Do you need a rental car on the Big Island?
Yes for most trips. Distances are long, and the Hele-On bus does not reach every beach, trailhead or viewpoint, so book a car for the whole stay.
Is Kilauea still erupting?
Activity at Kīlauea changes. Check the USGS Hawaiian Volcano Observatory and nps.gov/havo for the current status before you plan the day.
Is Mauna Kea worth driving to?
Yes for sunset and stargazing, if you can handle the altitude. The summit is about 13,800 ft, and the upper road needs four-wheel drive, so a guided tour takes care of the road.
Should I stay in Kona or Hilo?
Kona for dry weather, beaches and restaurants. Hilo for rain forest, waterfalls and a quieter town. Volcano village suits early starts to the park.
How do you get from Kona to Hilo?
By car over Saddle Road (Highway 200), about 1.5 to 2 hours. Check the road conditions before you go, since the road is narrow and winding in places.
