Oahu Grand Circle Island Tour: Full-Day Scenic, Cultural & Surf Highlights
Select participants and date
The bus eases out of Waikiki before dawn and the island unfolds like a hand-drawn map—crater rims, reef outlines and a spine of green ridgelines that catch the light. On the Oahu Grand Circle Island tour, sights arrive like chapters: Diamond Head’s blackened rim rising over the southern shore, the turquoise splice of Hanauma Bay tucked inside a volcanic cove, and the raw drama of the wind-sculpted Halona Blowhole where the ocean insists on being noticed.

Adventure Tips
Start early to beat traffic
Pick the earliest pickup you can; Oahu traffic can add 30–60 minutes between stops during peak hours.
Bring reef‑safe sunscreen
You’ll visit marine areas—use mineral-based, reef-safe sunscreen to protect corals and sea life.
Pre-order lunch if you want hot food
Pounders requires pre-orders for island-style lunches; otherwise bring snacks for the bus portions between stops.
Layer for wind and sun
Coastal lookouts can be windy and sun-exposed—light windbreaker plus sun hat will cover both conditions.
