On July 24, 2009 I soloed the scramble route up Eiffel Peak in Lake Louise, Banff National Park. Technically there is a hiking restriction of a minimum part of 4 to get in this area but I simply hiked between groups of tourists that were slower than me and figured as long as I stuck with the groups, I’d be fine. There are a LOT of people on the trails in this area in the summer anyway, but you should be aware that there are stiff fines if you are hiking solo.
