Start this hike early in the day. I started late and ended up doing the steep rocky descent when it was getting dark and drizzling, which made it feel much harder. Once you hit the lakes it becomes easy, but the upper rocky section needs proper shoes and slow steps. Leave the summit before 3 PM so you reach the lakes in daylight. With better timing and good grip shoes, this route becomes a smooth and enjoyable hike instead of a long, tiring one.

The best view to be had of these two lakes is from the Crib Goch, and they will be a long way below you.

I only walked part of PYG Track on the way up to the Crib Goch diversion. But this seemed a very straightforward hiking path to follow.
