Mountain-Biking in the National Park is restricted to ROADS ONLY.
There are a few shingled roads that make good riding:
MT WHITE ROAD
The turnoff from SH 73 is 25km from Arthur's Pass towards Christchurch. This road climbs up hill and down dale following the Waimakariri River to Mt White Station.
POULTER RIVER to TRUST-POULTER HUT
Warning: Casey Hut in the Poulter Valley has burnt down! Next available hut in the valley is the Trust-Poulter Hut about 5km upstream of the Casey Hut site; it only has 6 bunks! Carry a tent otherwise.
A report by DOC recommends not replacing the 48 year old Casey Hut that burnt down in the Poulter catchment late last year. The Federated Mountain Clubs (FMC) and others are not comfortable with this decision and is seeking public feedback from club members and other Park users. Visit goo.gl/forms/R8u2HPu2CG to make your opinion known!
Near the end of the Mt White Road is the Poulter valley. There is vehicle access up the Poulter river on a four-wheel drive track, as far as the National Park Boundary at Mt Brown Creek. Beyond this point mountain bikes are permitted to follow the "road" and walking track as far upstream as the Trust-Poulter Hut on the true-right of the Poulter River. Cyclists are NOT PERMITTED on the Andrews Valley track system. This is on a 3 year trial period and is the first time cycling has been permitted in a National Park.
The access up the Taipo starts just west of the Rocky Point Scenic Reserve ( Approximately 40 km drive west from Arthur's Pass). It is possible to Cycle up to Seven Mile Hut, about an hour riding.
It may be possible to approach local landowners to ask permission to cycle on private land - Stations such as Flock Hill Lodge have many 4 wheel drive roads that are suitable for mountain-biking.
