Mt Arnold

From the Dingle Burn Valley near the historic Ben Avon Hut, follow up the
obvious tree line on the north side of the side stream on the true right of
the Dingle Burn. Gain height to about 1200m. Continue to sidle along the hill
towards the basin until you get bluffed out. There is a slip near here you
can drop down into the river below fairly easy. Head up the river for a few
hundred meters to enter the basin. Following the creek on the way in/out will
see you stuck in a small canyon. From the basin head up the obvious slopes
leading to Mt Arnold. Easy way up summit rocks is from the saddle on the
North Side.
