Bottom line first: Hawaii’s Big Island is an “island in active geological motion” — Mauna Loa could still erupt, and Hawaii Volcanoes National Park is the only park in the world where you can stand at the edge of an active volcanic crater. Allow 2 full days for the volcano. The Big Island’s total area is twice the combined area of all other Hawaiian islands — self-driving is the only sensible approach.
Hawaii’s Big Island (officially Hawai’i) is the largest island in the Hawaiian archipelago and the geologically youngest — home to 5 volcanoes, two of which, Mauna Loa and Kilauea, remain active today.
Must-See Attractions
1. Hawaii Volcanoes National Park
Highlights:
- Kilauea crater viewpoint (Steam Vents)
- Thurston Lava Tube
- Night viewing of glowing lava (subject to eruption activity)
Reminder: Check the park’s official website for current lava activity status before visiting — parts of the park may close temporarily.
2. Mauna Kea Observatories
At 4,207 metres, Mauna Kea is one of the world’s premier astronomy observation sites, home to 13 of the world’s leading telescopes.
Stargazing tour: Departs from the visitor centre after sunset, approximately 4 hours, €130/person, including cold-weather gear and hot drinks.
3. Kona Coffee Farms
The Kona region of the Big Island is one of the world’s finest coffee-growing areas — “Hawaiian Kona” is a globally recognised brand. Farm visits are free; €5 covers a tasting of 5 varieties.
Self-Drive Route
Classic 2-Day Route:
| Day | Route | Highlights |
|---|---|---|
| Day 1 | Full day at Volcanoes National Park | Lava tube, volcanic crater |
| Day 2 | Mauna Kea stargazing + Kona coast | Sunset stargazing, ocean views |
Car hire tip: The Big Island is large with scattered attractions — a rental car is essential. Book through AutoEurope — jeeps/4WD SUVs run approximately €70/day, 25% cheaper than airport counter rates.
Maui Water Activities (From the Big Island)
Book Maui boat trip activities via Klook:
- Maui whale watching season tickets (December–April): approximately US$120
- Snorkelling with dolphins: approximately US$95
eSIM Recommendation
AT&T, Verizon, and T-Mobile all cover the Big Island, but mountain and volcanic areas have weaker signal. Consider purchasing an Airalo US eSIM — 15 GB/30 days for approximately €30; 4G coverage is adequate for most of the trip.
