Through the Arch: A Bay of Islands Passage to Cape Brett and the Hole in the Rock
A short boat passage that delivers big coastal drama and close encounters with dolphins and seals.
The boat noses through a mirror of water and the island’s silhouette slides into focus: a vertical slice of sky where the sea has eaten through stone. For decades, sailors and sightseers have kept this moment on their short lists—the slow approach, the low rumble of the engine, and then the arch itself, a clean gouge in Motukōkako, commonly known as the Hole in the Rock. Out here in the Bay of Islands, the sea insists on being noticed. It dares you to come close and rewards you with a particular kind of coastal drama.
Trail Wisdom
Dress for spray
A lightweight waterproof jacket and secure shoes make wet decks comfortable; even calm days can produce spray near the arch.
Bring binoculars
Wildlife—dolphins, seals and sea birds—often perform at a distance; binoculars ensure you don’t miss the details.
Plan for seasickness
Take preventative medication or ginger an hour before departure if you’re prone to motion sickness.
Respect wildlife and culture
Follow crew guidance around sensitive sites and avoid approaching hauled-out seals or nesting birds.

Common Questions
Can boats actually pass through the Hole in the Rock?
Yes—skippers will attempt passage when sea and weather conditions are calm and safe; captains always prioritize safety and may instead route around the arch if conditions are unsuitable.
Where do trips depart from?
Most tours depart from Paihia or Russell; choose a departure point convenient to your accommodation and check boarding times when you book.
How long does a typical cruise last?
Expect between three and five hours, depending on the route, wildlife sightings and any island stops included in the itinerary.
Will I see dolphins and seals?
Dolphins are commonly sighted in the Bay of Islands and seals haul out on nearby rocks; sightings cannot be guaranteed but tour operators have high encounter rates.
Is the experience suitable for children?
Yes—many family-friendly operators run the trip; ensure young children wear life jackets provided by the crew and are supervised on deck.
Do I need to bring food and water?
Many tours provide bottled water and sometimes snacks, but it’s sensible to bring your own water and a light snack, especially on longer trips.
What to Pack
Waterproof jacket (spray and rain protection), binoculars (wildlife viewing), sea-sickness medicine (prevent nausea), layered clothing (variable coastal weather).
