which placeses are more suitable for travelling for this season?

I'd suggest Canada! There are lots of cool things to see here! But its such a big country, you'd have to pick a part of it that you would like to see. The East Coast has rugged coastlines, whale watching, icebergs (in spring in Newfoundland), Viking settlements, historic forts, beautiful scenery and great seafood! Quebec and Ontario have the Great Lakes, Niagra Falls, the St. Lawrence River, Montreal, Toronto, Ottawa, lots of festivals. The prairies have ... I don't know. I've never been there :D Alberta and British Columbia have the Rocky Mountains with glaciers, skiing, resorts, hiking. The north has tens of thousands of miles of untouched wilderness.
