If you go to Banff National Park, don't miss the adjacent and far less known Yoho National Park. There is a particular section of the park that is best reached by bus because of the long, boring, steep climb to get to it. That part of the park allows only about 4 busloads each day and is my favorite part of the entire area near Banff. The reservations for the bus ride are best made two (or is it three?) months ahead of time to the day when the tickets go on sale. My experience is that the tickets are sold out within the first few hours.
All photos shown here are from Yoho. All but Photos #3 & #4 are from that special area of the park reached by bus, as is the photo that I posted earlier here. They were captured in 2009 and converted recently to black-and-white.
C&C encouraged, though I have no questions to ask.
