This hike has been judged amongst the Top 10 hikes in the world and amongst the top hikes in Canada. It is an extreme outdoor adventure climbing almost 1000m and 10km one way or 20 bone crunching km in and out. About 1 km away from the lake (a glacial lake) are two Indiana Jones heart stopping encounters with ones fear of heights, not to mention death, paramount in the experience. The first is a ledge climb with the width being about a metre for 25 metres then crawling or bending through a tunnel in the rocks – which I must admit I could not work out if it was a natural walk way or man made, to access this one climbs a metal ladder up about 2 meters. At the end of the tunnel, one is confronted by a precipitous gorge and another ledge crawl, the width of which is such that to minimise the chance of missing one’s footing and plunging a thousand metres into the ravine, there is a steel cable drilled into the rock face every few metres.

Once negotiated, there is a further 1km track to a breathtaking glacial lake. The only way to do it justice is with photographs.

Having eaten lunch, sitting with bare feet in the deliciously icy water, teaming with trout, one repeats the whole adventure.

It was, to add to the sense of masochism, 32 degrees in a burning sun despite being at more than 3000m .

Have just had dinner in the dining room of the Prince of Wales hotel! It has a Scottish theme! The staff are in kilts and at 8pm in the lounge is a talk on the history of Waterton and the Prince of Wales hotel, given by a young Asian man in a kilt!
