Galapagos Sharks Circle a Floating Cage off Oahu's North Shore
A boat out of Haleiwa, a cage moored a few miles offshore, and Galapagos and sandbar sharks swimming right up to the bars.
North Shore Shark Adventures runs this trip from Haleiwa Small Boat Harbor. The cage floats at the surface with its top about two feet above the water, so you hold the bars and look down. Masks and snorkels are provided. Fins are not needed.
The listing sells two seats on one boat: a cage spot, or an observer seat that stays dry on deck. Book both for the same time slot to ride together. The headline price is the child or observer fare; adults in the cage pay more.

The operator says its cage holds up to eight people. Travelers in 2025 and 2026 describe going in by groups of four or five, with everyone else watching from the deck until their turn. Each person gets one turn in the water, and swimming outside the cage is not allowed.
Hold the side rails and hook your feet under the foot bar. Several travelers say the cage rocks with the swell, and bracing makes it easier to keep watching. Two travelers noted that by the second group's turn, the sharks can be a little less active.
The operator says the sharks are mostly Galapagos and sandbar, with an occasional tiger or hammerhead. It also says it does not chum: the engines sound like a crabbing boat, and the sharks come to that sound.
The Ride Out Sets the Morning
Reviews from 2025 and 2026 keep repeating one warning, and it concerns the water. The ride out and the cage itself can be rough, and several travelers were sick on the boat. The operator does not sell motion-sickness remedies. It suggests taking one the night before and again at least an hour before boarding, and eating at least an hour ahead. There is no bathroom on board.
Morning boats tend to meet calmer water. The operator runs its earliest departures first and says stronger wind later in the day can cancel later trips. Weather does cancel tours: two travelers in November 2025 lost their dates to wind, one of them twice. Booking early in a stay leaves room to try again.
On the way out, travelers have spotted spinner dolphins, and in winter and spring, humpback whales.
Who Goes In, Who Stays on Deck
No swimming is required. The listing does ask for at least moderate fitness and the strength to climb down and up a vertical ladder, and the crew helps people in and out. The cage is recommended from age five, at the captain's discretion and depending on conditions.
Children under three travel free. The operator's own booking page accepts infants only on boats before 9:00 AM. With a baby along, pick an early time. Every booking needs an adult, and the listing allows travelers up to seven months pregnant.
Anyone who would rather stay dry can take the observer seat on the same departure and watch the sharks from above.
Self-Drive to the Shark Shack
This listing has no hotel transfer. You drive yourself to Haleiwa Small Boat Harbor, and the operator puts the drive from Waikiki at an hour and a quarter to an hour and a half. Without a car, the operator says the city bus from Waikiki takes two to three hours each way.
Check in at the operator's kiosk, the Shark Shack, 30 minutes before your boat. Staff there point you to free parking. The listing also asks you to call 48 hours ahead to reconfirm.
Its calendar runs boats every half hour from 7:00 to 10:00 AM, with 6:00 and 6:30 AM boats added from May into summer. That is the calendar as checked in October 2026.
