Tie Dye Arch: exposed Poor Knights swim-through for calm days
Tie Dye Arch is a boat-only, weather-dependent dive best on flat, clear days, with a split-entrance swim-through and fish-filled walls.
About Tie Dye Arch
Tie Dye Arch is a colourful boat-dive swim-through on the exposed Pinnacles side of the Poor Knights Marine Reserve. On calm days, the split entrance, encrusted walls, and boulder-strewn floor make it a strong route for photographers and fish watchers, with schools of maomao, kingfish, rays, eels, and the occasional seal.

Local Intel For Tie Dye Arch
Community notes to help plan your visit.
Scuba Diving
Scuba divers usually work the arch as a controlled swim-through, using the cleaner side of the structure for entry and exit. Slow down in the boulders and arch walls, where the best fish action often gathers.
Freediving
Not a primary freedive site. Boat access, overhead geometry, and exposure make it a better fit for scuba than casual apnea unless conditions are exceptionally calm and the team is experienced.
Snorkeling
Only a secondary snorkel option. Very calm water can make the outer structure interesting from the surface, but the site is much better suited to scuba and operator-led boat days.
