Dress for spray
A lightweight waterproof jacket and secure shoes make wet decks comfortable; even calm days can produce spray near the arch.

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.

Wildlife—dolphins, seals and sea birds—often perform at a distance; binoculars ensure you don’t miss the details.
Take preventative medication or ginger an hour before departure if you’re prone to motion sickness.
Follow crew guidance around sensitive sites and avoid approaching hauled-out seals or nesting birds.

Operators work within marine park guidelines to minimize disturbance to wildlife; visitors are urged not to feed or approach animals and to dispose of waste responsibly.
Spring brings active birdlife and fewer tour groups, but weather can shift quickly—layers and a waterproof are recommended.
Summer is peak season for calm, warm conditions and great wildlife viewing; expect busy docks and limited last-minute spots.
Autumn offers excellent light and comfortable conditions, though windy days can still push operators to avoid the arch.
Winter trips can be atmospheric and less crowded, but expect cooler, wetter weather and a higher chance of choppy seas.
Shoot the arch at golden hour for warm light; use a polarizing filter to cut glare and boost color; a mid-range zoom (24–200mm) covers both wide seascapes and closer wildlife shots; pick a fast shutter (1/500s or faster) for dolphins and a tripod on calm decks for low-light scenes.
Protects against spray and sudden weather changes while on deck.
Helps observe dolphins, seals and seabirds at a safe distance.
Prevents nausea on choppier days so you can enjoy the trip.
Captures both wide seascapes and closer wildlife portraits from the boat.
