Moderate — comfortable with a 5-mile downhill bike ride and swimming/snorkeling for up to 1–2 hours in protected waters
From a ridge above Honolulu to coral gardens off Waikiki, this half-day combo packs a 5-mile downhill bike and a catamaran snorkel into one seamless loop. Expect ocean views, expert narration, and hands-on guides for families and active travelers.
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.

The tour includes time snorkeling over coral—use reef-safe sunscreen to protect marine life and reapply before boarding the boat.
Sturdy sneakers that grip pedals and handle short walks at lookouts will make the descent more comfortable.
Keep your phone, wallet, and a spare shirt dry during the sail and snorkel—most boats have limited dry storage.
If you’re prone to seasickness, take medication or use acupressure bands before boarding the catamaran.
The route passes Punchbowl Crater (Puowaina) and Tantalus (Puʻu ʻŌhiʻa), places woven into Honolulu’s modern development and older Hawaiian land divisions.
Snorkel sites are sensitive—guides emphasize no-touch rules and encourage reef-safe sunscreen and responsible behavior to minimize coral damage.
You’ll be snorkeling from a catamaran—wear or bring a quick-dry swimsuit for the water segment.
