Thorne Bay to Milford Beach
The section of the North Shore Coastal Walk from Thorne Bay to Milford Beach is better formed than from Fossil Point to Thorne Bay, despite the rocky section of coast. It is mostly sealed, with one section that goes along a covered water pipe to a waste water pumping station on Black Rock. This is a larger rock outcrop with a great viewpoint.
The most interesting part of this section is the historical attempts at encroachment from some of the adjacent private properties to the water line. There are some examples of rock walls, which the track runs through, and even the remains of an attempt to wall off a swimming pool. It presumably filled with water at high tide!
Beyond Black Rock, the track rounds another rocky point to Milford Beach.
