Mt Guy is a prominent peak from Lake Clearwater Huts, and its almost impossible for a trail bagger of any sort to turn up the chance to check out the view on top of this one.

Park up in the village and head down to the shoreline of Lake Clearwater to pick up the trailhead. The first couple of kms is nice 4WD trail around the lake, crossing Lambies Stream outlet. Then the climb proper begins, steady to start but it gets steeper and steeper and gnarlier as you climb.

As you climb the views become more and more expansive, up into the headwaters of the Rangitata - famous High Country Station Country. Mesopotamia, Erewhon, its all up here, with Mt D'Archiac and the Main Divide to Mt Cook on full display if the weather plays its part. Lord of the Rings country for those that way inclined, you can see why this countryside filled in for Rohan in the films.

Eventually after an hour or so of serious uphill grunt things start to level out and you'll find the massive summit cairn on a wide and comparatively flat summit.

Two options for the return, retrace your steps - or else head west along the summit and descend the ridgeline to hook up with part of the Te Araora Trail which passes to the western flank of Mt Guy.

Not a long day, but certainly a steep one and if its hot, a refreshing dip in Lake Clearwater will invigorate the most hard core of us!

This trail includes the peak Mount Guy.

Another honest uphill push with enough technical downhill to really wake up the legs. Completed on a very crisp day, but I had no trouble keeping warm!

Nice little run with stunning view over Ashburton Lakes. Like Alice - we had fog at the top so no view, but loved the moody atmosphere and caught the views on the way down. Would go again :)

I really feel like I was robbed.... couldn't see a thing. Might have to do it with Mystery Lake next time ... and hopefully a view! Good fun though!!!

A really cool trail. Easy running to begin as you go along a 4WD track and then comes the long grunty up! Great views at the top - stunning!
