Estimated Times to Run







This is a fantastic scenic loop that can be done in either direction but is best done clockwise.

Starting in the Red Hills carpark follow the well signposted track to the start of the Wots Up DOC Mountain Bike track. This well built (by the Nelson Mountain Bike club) well graded track climbs and zig zags its way through beech forest up and onto the open tops of Beebys Knob, where there are beautiful views in all directions.

Carry on until you arrive at the Junction with the Maitland Ridge track. Turn right (East) onto the Maitland Ridge track and run along this narrow undulating single track through mountain beech forest interspersed with open clearings keep an ear open for mountain bikes coming behind you. Eventually the open mass of the Red Hills comes into view and you drop down to the sweet little Red Hills Hut - this area is stunning and unique as the ultramafic red rock of the Red Hills means forest doesn't grow on them in stark contrast to the beech forest you've just run through.

From the hut the track follows an old 4x4 road back down to the carpark.

You can add to this run with a side trip visit to Beebys Hut from the Maitland Junction - carry on North along the 4x4 road for 3 km the views along this side trip are well worth the extra effort.

This is a very runnable circuit the beautifully graded trail means there's very few places the track is over 7% in grade but only if you do it Clockwise ! Take plenty of water with you as for 14 kms there is none available.

Stunning views of Nelson Lakes National Park and Raglan Ranges plus the Wairau Valley and the magical Red Hills.

If you know of any public toilets near the trail start or on the route, please login and then let us know so we can update this section.

This is a great loop, superb on a fine day and would also be good if the weather wasn't perfect as most of the time you're fairly sheltered. Thanks to our mountain biking friends who built both the bottom (Wot's up Doc) and the top (Maitland ridge) trails!

This is a great route to run and has wonderful views. Red Hills Hut is very cute and a nice place to stop before the final descent.

The climb up is long but mostly runnable. The 8km technical section on Maitland Ridge Track is really fun and there’s an easy 6km descent to finish. Route finding is easy although note that the 4x4 track does not end at the car park. It leads back into the beech forest for another 2km or so of bush tracks to complete the circuit.
