The Tunnel Beach Track is a popular short walk south of Dunedin that leads through dramatic sandstone cliffs to a secluded beach via a historic hand-carved tunnel. The track offers spectacular coastal views and opportunities to see New Zealand sea lions resting on the sand. It forms part of Dunedin’s network of accessible day trips and walking experiences on the Otago coast. Visitors should check tide times, track conditions and car park hours before setting out, as the steep descent and tidal beach require careful planning. The route is managed by the Department of Conservation with support from Dunedin City Council for the car park.

About Tunnel Beach Track
Tunnel Beach Track descends from a car park 150 metres above sea level through five viewpoints known as “nests” to a hand-carved tunnel and small beach. The route showcases sea-carved sandstone cliffs, rock arches and a natural land bridge while protecting critically endangered coastal turf on the headland. Stay strictly on the formed gravel path to avoid trespassing on surrounding private land and damaging the fragile turf ecosystem.
The tunnel was commissioned in the 1870s by local politician John Cargill for private family access. Concrete steps were added in 1983 when the track opened to the public. The passage remains dark with a low ceiling and no handrail to preserve its heritage fabric; a torch is recommended.
The beach itself is not suitable for swimming due to strong currents, rogue waves and unpredictable tides. Visitors are advised to time their arrival around low tide and keep at least 10 metres from any sea lions or seals resting on the sand.
Access and Parking
Reach the track by taking the signposted turnoff from Blackhead Road onto Tunnel Beach Road. The small car park at the end is managed by Dunedin City Council and has strict opening hours. Vehicles left after closing will be locked in and may be impounded. Do not park on the roadside, yellow lines or private driveways, as towing is enforced. Public transport options are limited; most visitors drive or take a short taxi ride from central Dunedin.
The Track and Tunnel
The well-formed gravel path is steep in sections and requires shoes with good grip. The short option reaches the first viewpoint in about 10 minutes for panoramic coastal views. The full return journey to the tunnel and beach takes around one hour. Bikes are not permitted due to the narrow switchbacks and high visitor numbers. The tunnel leads directly onto the secluded beach nestled among towering cliffs.
Wildlife and Conservation
New Zealand sea lions (pakake) frequently rest on the beach and can be difficult to spot when stationary. Keep at least 10 metres away and move calmly if approached. The headland supports critically endangered coastal turf, a rare community of low-growing native plants found in only a few hectares nationwide. Visitors must stay behind barriers and on the track to prevent trampling and erosion.
Hazards and Safety
Cliff edges can be slippery and unstable after rain. The beach is tidal and prone to rogue waves; check tide forecasts and avoid swimming. Cell phone reception is unreliable. In the event of a long or strong earthquake, sudden sea-level change or unusual sea noises, move immediately to higher ground. The track has experienced temporary closures after severe weather; always confirm current status on the DOC website before travel.
Day Trips from Dunedin
Tunnel Beach Track makes an ideal half-day or afternoon outing from central Dunedin, with a drive of roughly 20–30 minutes. Combine the walk with nearby coastal stops or return via the scenic route through St Clair for a relaxed day exploring the city’s southern shoreline. The short duration and dramatic scenery suit visitors seeking an accessible introduction to Otago’s rugged coast without committing to longer hikes.
What Visitors Often Say
The steep descent is rewarded with breathtaking cliff views and the thrill of emerging from the historic tunnel onto a quiet beach. Many appreciate the chance to see sea lions up close while noting the need for sturdy shoes and awareness of tides.
Visitors describe the track as a highlight of a Dunedin stay, praising the dramatic geology and sense of discovery. Some mention arriving early to secure parking and checking conditions after rain to avoid slippery sections.
