Southeast of Nelson and southwest of Canvastown in the Mt Richmond Forest Park, the Wakamarina Track is roughly a 20km route. It is best ridden from south to north so that it get more difficult as you continue. It can be steep and very rough, especially between Devils Creek Hut and Fosters Clearing.
To reach mountain biking at the northern trailhead from Havelock, head west for 9km to Canvastown. In Canvastown, head southwest for 15km up the Wakamarina Valley to Butchers Flat car park. A road suitable for 4WD vehicles only continues a further 1.5 km to a carpark just before Doom Creek.
To reach the southern trailhead (Blenheim side), turn off State Highway 6 on to Northbank Road, 6 km north of Renwick (16 km from Blenheim). Follow Northbank Road for 5 km, then Onamalutu Road for 11 km, past Onamalutu Domain, to Flowers Creek ford. A final 5 km up Kiwi Road leads to the car park at the start of the track.
Road access is also possible from Bartletts Valley. This route to the track is longer and recommended for 4WD vehicles only.
Overall, Wakamarina Track is the 18th most popular mountain bike trail of all 41 mountain biking rides in New Zealand.
