Best Time to Book Cheap Flights

Hilo’s fares are often somewhat more moderate than those to Kona, given the smaller number of visitors drawn specifically to the wetter, greener eastern side of the island.
About Hilo
Hilo is the largest town on Hawaii’s Big Island and its historic county seat, known for its farmers market, botanical gardens, and dramatic waterfalls like Rainbow Falls and Akaka Falls. It serves as the natural base for visitors exploring Hawaii Volcanoes National Park and the island’s lush, rain-fed eastern landscapes.
Things to Know When Flying Into Hilo
Hilo is the closest airport to Hawaii Volcanoes National Park, roughly a 45-minute drive, making ITO ideal for volcano-focused itineraries.
The eastern side of the Big Island receives significantly more rainfall than the western Kona side, contributing to its lush, tropical scenery.
Some visitors choose an open-jaw itinerary, flying into Hilo and departing from Kona (or vice versa) to see both sides of the island without backtracking.
Rental cars are essential, as the Big Island’s attractions are spread across a large geographic area.
