What to do in Hawaiʻi Island (Big Island) when it rains

A wet day does not need to become a scramble. Start with one indoor anchor, keep the rest of the day nearby, and save the outdoor plan for a better window.

Replace an outdoor block:

Rain-plan replacement: Keep the outdoor anchor while conditions are clear.

Hawaiʻi Volcanoes National Park Crater Rim Drive on Hawaiʻi Island

Kīlauea Iki Trail on Hawaiʻi Island

Before you go

Use the live details that matter

  • A rental car is essential for a first visit. Both Kona and Hilo can serve different parts of the island, but neither makes the island small.
  • Volcanic activity, air quality, road conditions, park access, and ocean conditions need a current check.

Confirm current access, hours, reservations, and conditions with Official Hawaiʻi Volcanoes National Park Crater Rim Drive information.
