Tunnel Beach lies on the coast south of the city, where soft sandstone cliffs have been carved by the Pacific into arches, caves and stacks. A farm track leads across sheep paddocks to the edge of the cliff, where a tunnel hand-cut through the rock in the 1870s leads down to a small, enclosed beach. The tunnel was dug by the family that owned the land so that they could swim in privacy, and it has become a local legend. Today the track and the tunnel are popular with walkers and photographers, and the contrast between green farmland and blue sea is striking. A short stairway leads through the tunnel to the beach, where the arch and the rock formations make a memorable scene. The surrounding cliffs offer views up and down the coast, and on a clear day you can see the peninsula in the distance. The track is steep and exposed, so it requires reasonable fitness and care, particularly in wet weather. It is a short drive from the city, which makes it an easy outing, but conditions can change, so check the local council information about access before you go.
How to visit
Tunnel Beach is about 15 minutes south of the city centre by car, near the suburb of Blackhead. There is a small car park at the start of the track. The walk down takes around 20 to 30 minutes, with a steeper climb back, and the whole visit takes about an hour or two.
The track crosses farmland, so keep to the path and close gates behind you. Access can be restricted at certain times of year, such as during lambing, and the beach is only accessible at low tide in some conditions, so check before you travel.
What to expect
The track descends across open pasture toward the coast, with views of the cliffs. At the bottom, the tunnel stairs are narrow and can be slippery. The beach is small and rocky, and waves can reach high on the shore, so do not linger near the water. The arch and sea stacks are photogenic, particularly at sunset. Wind and sun exposure are significant, and there is no shelter or toilets on the track. Be prepared for sheep and mud.
Making the most of it
Wear sturdy shoes with good grip, carry water and a windproof layer, and bring a camera or phone. Visit at low tide and in settled weather for the safest conditions. Combine the walk with a stop at St Clair or a meal in the city. Take care with children, as there are steep cliff edges. Follow all signs, stay on the track and avoid rock climbing.
Good to know
The land belongs to a private farm, and the track is maintained with the cooperation of the council and the owners. The area is subject to erosion, so features such as the arch change over time. The tunnel and stairs are heritage features that require ongoing care. Visitors are asked to respect the farm and animals, and to take rubbish with them. Sunsets here can be superb, but the climb back in the dark is not recommended without a torch, so plan your timing carefully.
