In 1850 early European settlers arrived at the Port of Lyttelton. It was clear that the main settlement would be on the plains on the northern side of the Port Hills, in what is now Christchurch. And so the Bridle Path was constructed, a steep pathway across the Port Hills over which horses were led, carrying all essential supplies. It was the only means of traversing the hills until the Summit Road over Evans Pass was completed in 1857, and the rail tunnel was built in 1867. The Path rises to 350 metres from the Port of Lyttelton, and descends steeply into the Heathcote Valley. Click once on any image to enlarge.
