More ways to explore the area's outdoor wonders
You start above Honolulu with wind in your face and a view that keeps widening—the city grid, the crescent of Waikiki, Diamond Head blunt against the Pacific. A short van ride from Waikiki drops the group at Pu'u 'Ohia (Tantalus). Guides fit you with a Kona cruiser and a Bell helmet, give a quick safety brief, then point you toward five miles of downhill that feel more like permission to let the island pull you forward.

Bring a reef-safe sunscreen
