The Big Island is 4,028 square miles (bigger than all other Hawaiian islands combined). Most families underestimate drive times, try to see everything in one day, and book hotels in the wrong locations. Split your stay between Kona and Hilo, give yourself a full day at Hawaii Volcanoes National Park, and remember that Mauna Kea’s summit sits at 13,796 feet. The island welcomed 1.73 million visitors in 2024, and most of them made at least three of these mistakes.

TL;DR: The biggest mistake? Waiting. Book your Haleakalā sunrise reservation 60 days out at 7 AM HST sharp. Reserve your rental car when you book flights (Christmas 2025 saw $6,000/week rates). Budget a full day for Road to Hana. Book Old Lahaina Luau 3-4 months ahead. Everything else you can wing, but these four things will make or break your trip.
