Tunnel Gully

Updated 14 February 2019 11:14am

Nestled at the foot of Mount Climie (830 m) north of Upper Hutt, Tunnel Gully Recreation Area is popular for picnics, mountain biking and walking through the remnant native bush. There is plenty of parking, and flush toilets are provided.

Named for its link with the historic Remutaka Railway between Wellington and the Wairarapa, Tunnel Gully features the 253m long Mangaroa Tunnel, built between 1875 and 1877. The tunnel’s working life ended in November 1955 when the new Remutaka Tunnel was opened.  Tunnel Gully is now a popular spot for walking and tramping, mountain biking, and picnicking.

The shallow water of Collins Stream at the Tunnel Gully Recreation Area is ideal for paddling and swimming for young children. Stream water should be boiled before drinking.

How to get there

Walking only tracks

Tane's Track - Upper Tane's Track in Tunnel Gully 

  • Medium
  • 1 hour

Start at the lower picnic area and take the left-hand branch of the track through tall rimu, matai, kahikatea and tawa forest. Cross the road which once formed the old railway line, then climb through hard and black beech forest to Collins Stream and a picturesque waterfall. During the descent to the starting point you cross the Mt Climie access road then pass a grove of eucalyptus trees. This area was once the campsite for workers building the nearby Mangaroa Railway Tunnel, which was completed in 1877.

From the tunnel it is a short walk through podocarp/tawa bush back to the lower picnic area.

This walk is suitable for single mountain buggies.
