The hike starts and finishes at the same location as the Joffre lake trail. You'll need to hike to the third lake where where you'll turn off in a SW direction through the valley just before reaching the helipad close to the campground

From there, there'll be a trail all the way to the ridge at the valley where you'll be hiking up a giant mound of rock debris left from the glacier and up to the ridge between Mt Tszil and Mt Taylor.

Heading East the scramble up Mt Tszil is better if kept to the left as its a bit less gnarly, although it gets worse... from there the summit is in view. Start your assent of Mt Slalok any way you seem safest (be careful of lose and sharp rock),at some point just before the summit you reach a part which is pretty much vertical and its easy to lose footing.

Carrying on, be careful again as walking the ridge line meters before the summit can be lethal as one slip could result in a 600 foot drop.

Once arriving at the summit theres plenty of angles for photos and glacier walking if you fancy a cool down.
