Oahu Half-Day: Tantalus Bike, Waikiki Sail & Snorkel Combo
Bike down Tantalus with ocean views, then swap pedals for a catamaran to snorkel Waikiki’s reefs. This half-day Oahu combo packs rainforest ridgelines and crystal-clear snorkel spots into a single, active morning.
The Experience
Before You Go
Wear a swimsuit under your clothes
Change quickly at the park and avoid wasting time—swim first, dry off on the boat.
Bring reef-safe sunscreen
Sunscreen that’s safe for coral is required by guides and reduces harm to reef ecosystems.
Close-toed shoes for the bike
Sturdy sneakers protect during the 5-mile downhill which has intermittent gravel shoulders.
Hydrate before and during the trip
Carry a refillable bottle—heat and exertion on the downhill and on-deck sun exposure can dehydrate quickly.
Local Knowledge
Hidden Gems
- •Manoa Lookout viewpoint—great photo stop with fewer crowds than popular mirrors
- •Kewalo Basin seating area—watch local outrigger crews practice at dawn
Wildlife
- •Reef fish like parrotfish and surgeonfish
- •Frigatebirds and occasional spinner dolphins offshore
Conservation Note
Operators emphasize reef-safe sunscreen and no-touch snorkeling to protect coral; sticking to marked swim areas reduces reef damage.
Tantalus and Punchbowl areas sit atop volcanic tuff and are threaded with WWII and 19th-century Hawaiian history; guides often reference traditional place names and local stories.
Photographer's Notes
