Despite the mist, rain, sleet and snow pellets, it was definitely worth hiking at Lake O'Hara during golden larch season and we hope to do it again (in better weather) some time over the next few years. On the advice of Parks Canada staff, we covered about 9 km, hiking up the Lake Oesa trail, across the Yukness Ledges and then - after a bit of time exploring the Opabin Plateau - down East Opabin trail.
