Can You Swim at Cathedral Cove?
Swimming and snorkelling at Cathedral Cove: what the Department of Conservation says, the marine reserve rules, tides and the archway, boats near swimmers, and the snorkel trips.
Yes, you can swim at Cathedral Cove. The cove is part of Te Whanganui-o-Hei Marine Reserve, and the Department of Conservation lists swimming and snorkelling among the things visitors do there. Watch the tide, keep out of the archway when it is under water, and remember that boats and kayaks share the water with you. For a swim from a boat, Boom Sailing’s Whitianga: Experience Cathedral Cove; Sail, swim & snorkel, from US$92 a person (checked November 2026), anchors in the reserve for an optional swim or snorkel when conditions are good.
The morning sail leaves at 9:15 AM and the afternoon sail at 1:45 PM, or 11:00 AM in April; check in 15 minutes before, as the boat cannot wait for latecomers. You can cancel free up to 24 hours before.
What DOC says about the water
On the Department of Conservation’s pages (checked November 2026):
- Allowed. Swimming, snorkelling, diving and kayaking are listed as things to enjoy in the reserve.
- Boats nearby. There are no boat lanes separating boats, jet skis and kayaks from swimmers. Boats must keep to 5 knots within 200 m of the shore and within 50 m of a swimmer.
- Tides. At high tide the beach can be cut off from the track; low tide gives more beach and keeps you further from the cliffs. Do not go into the rock archway if it is under water.
- Lifeguards and rips. The beaches are not patrolled by lifeguards and have rip currents and big waves; DOC’s advice is to supervise children and, if in doubt, stay out.
- Rough seas. In rough seas waves surge through the rock archway and onto the beach, and DOC says not to visit in rough seas.
- Rain. Do not visit during or straight after heavy rain, when the landslide risk is high.
- Toilets. The nearest are on the track, a 10- to 15-minute walk from the beach.
There are no lifeguards on the beach, so plan your swim as if no one is watching: pick a calm day, stay near the shore and keep children within reach.
The reserve rules
Te Whanganui-o-Hei has been a marine reserve since 1992. Inside it you may not fish, take any marine life, shellfish, seaweed, rocks or shells, or feed the fish (Department of Conservation, checked November 2026). Look, swim and leave everything where it is.

Swimming from the beach
If you walk in, the swim is free: about 1 hour 30 minutes return on foot from Grange Road, with the beach at the end. Go at a lower tide for more sand, take water and anything you need for the day, and carry it all out again. How to get to Cathedral Cove has the parking, the shuttle and the walk, and tides and Hot Water Beach explains where to find tide times.
