Involution

Marsden Valley and Barnicoat Range

Involution is an intermediate-difficulty shared track that descends from the top of Barnicoat Range into Marsden Valley. The track passes through native bush the whole way down, and is the second-longest continuously descending MTB track within close range of any city in New Zealand (nearby Te Ara Koa is the longest).

Elevation profile: top of Involution to Marsden Valley Rd

This elevation profile should be considered approximate. Its accuracy is determined by the quality of data available.

 

Access

  5 min from Stoke

 

All Marsden Valley and Barnicoat Range trails can be accessed off the end of Marsden Valley Road, 5 min from Stoke. At the end of Marsden Valley Road, just before the quarry, there is a small car park on the right. Here you will find an information panel with a map and details on trail times and distances. There is also plenty of room to park alongside the road.

 

The uphill end of Involution starts on Jenkins Hill 4WD Road, right at the eastern end of Widdershins, at 715 m elevation. The most straight-forward way to reach the start of Involution is via Glider Road and Widdershins. Combining the latter two trails with Involution creates a 11.5 km circuit from Marsden Valley. The start of Involution is signposted.

Description

The track descends gently through beech and kamahi forest off the top of the range. Further down there are a series of tight zig-zags and the surrounding bush becomes more of a broadleaf mix. The track passes through two lush gullies, crossing small tributaries of Poorman Stream in each, and then descends through a series of sweeping zig-zags where the surrounding bush again transitions to kānuka. The bottom of Involution crosses the track to the historic Ngawhatu Weir, then drops into the gully next to Poorman Stream, winding for a further 150 m to the end at the Loop Track stream crossing. Turn right and follow the 4WD road 500 m back to Marsden Valley Road.

 

Whilst it is predominantly used for mountain biking in the downhill direction, it can also be completed in either direction on foot. If you’re heading uphill, the native bush and winding track provides a more interesting experience and a gentler gradient than nearby Glider Road (just be cautious of mountain bikers coming down).

 

Involution has a technical rating of moderate, though aside from negotiating a few rocks and roots, and some tight turns, the track shouldn’t pose too much of a challenge for less-experienced riders. Involution is on Nelson City Council land but is managed by the Nelson MTB Club.
