Access the Ohakune Old Coach Road from Ohakune or Horopito. It's a one way walk or ride so you'll need to return the same way or arrange transport back.

From Ohakune:
Start at the the historic Ohakune railway station, ride down Old Coach Road and turn right into Marshalls Road to join the track. Or, drive to the Marshalls Road car park (5 minutes drive from Ohakune) and begin the ride there.

From Horopito (north of Ohakune on SH 4):
Turn onto Matapuna Road from SH4. There is a parking area just across the railway line.

If you start/end the trip at Ohakune Railway Station or in Ohakune town centre, you will need to ride along public roads that are shared with cars. You can avoid this by starting/finishing at the Marshalls Road car park.
