This mountain is the highest peak between the rest of the Aoraki/Mt Cook region and the Kaikoura Range. Its size and location allows it to be seen from as far as Ashburton.
Those intending to climb Mt D’Archiac and/or neighbouring peaks or planning to cross Separation Col into the Godley region will need to use the Havelock Valley for access. Terra Nova Pass can also be used to access the Godley from the Havelock.
Four wheel drive vehicle access beyond Erewhon Station, at the head of the Rangitata River system, and some way up the Havelock, is possible, but access is dependent on the state of the rivers. For those on foot, cross the Clyde River after Erewhon Station and follow the north bank of the Havelock River to Freezing Point. Cross the Havelock River and continue to Mistake Flats Hut at the confluence of the Forbes and Havelock Rivers. This is an eight bunk DoC hut (~800m, grid ref: BX17 133 868) and is situated at the back of the flats near the beech forest. From Mistake Flats Hut to Separation Col allow 6-8hrs.
