Location: Lies between Grenada Village and Horokiwi to the north, Woodridge to the east and Newlands and Paparangi to the south.
Entrance and exit points: Mark Avenue in Grenada Village, and Colchester Crescent in Newlands.
Brief description: Belmont Stream, a tributary of Porirua Stream, flows through the park.
Further up the valley is a dog exercise area that extends as far as a stand of titoki and tawa, a remnant of the original forest.
Beyond this is an open area with picnic tables beside the stream.
The well-formed main track then climbs up to the Colchester Crescent entrance in Newlands.
Parking: Large car park at Mark avenue entrance.
Accessibility: Easy walk from Mark Avenue up the valley, but there are stepping stones across Belmont Stream. Track uphill to Colchester Crescent is steep in places.
Dogs: Off-lead dog exercise area halfway up the valley.
Features: Seton Nossiter Park contains the concrete abutments of the viaduct built in 1885 by the Wellington and Manawatu Railway Company. At the time it was New Zealand’s biggest timber viaduct.
Two of the abutments can be seen in regenerating bush near the main entrance at Mark Avenue, Grenada Village.
History: The park is named after Seton Nossiter, a local farmer and a member of the Hutt County Council for the Makara Ward from 1966 until the area became part of Wellington City. He was then a city councillor until 1977.
Mountain biking: Permitted.
