This was the Yoho Rollercoaster, as Zeljko put it. We went through the valley, up to the Twin Falls, over the Whaleback, down to Glacier Des Poilus, up Isolated Peak, down to Little Yoho Valley, up to the Iceline and back down to the parking at Takakkaw Falls. A very long day! The hike was fun and this area is beautiful. The scramble up Isolated Peak was the worst scramble I've done. We went up the wrong route up terrible rock, short ledges, mud, snow, water, etc. Only two of us made it to the summit, the rest of the group waited at the bottom.
