After seeing pics of the Jasper and Banff national parcs in Canada, I decided to go there myself on a short holiday trip next year. Timing though seems difficult. Here are my considerations: April: can be very cold (I'm no hero to spend days in the cold), May: only possible after 22nd (due to friends marriage and important family stuff), June: bears are in their agressive mode when they are with young. I will go on my own and although I had some serious training in fighting techniques, I don't think that will be enough against bears. ;-) July: high season for tourism. I don't quite like that.
Any advice on the best time to go inbetween April and high summer or maybe is my information incorrect on the bears or temperature?

Thanks in advance.
