Introduction: A Two-Island Adventure Across the Alenuihaha Channel
The road trip from Kailua-Kona on the Big Island to Wailea on Maui is a rare inter-island driving adventure. While no bridge connects the islands, a ferry crossing the Alenuihaha Channel—known for its strong currents and winds—makes this journey possible.
