We'll hike to Semaphone Lakes, where we'll camp and explore the alpine surroundings. This can include hiking to the waterfall and to the upper basins or scrambling to Locomotive, depending on the group's preferences and skills and on the weather.  The idea is to do hikes kids can participate on (my 9-yo is coming along), although part of the group can decide to choose more challenging objectives.

We'll leave either early on Saturday (21st) or late afternoon on Friday (20th) - in which case we'd camp at Nairn Falls Prov Park to break the long (~3.5hr) drive from Vancouver.
