I'm looking at planning a trip over there next year and am wondering about a suitable National Park to visit. I want to paddle and hang and am happy to go anywhere, but I will need a place to hire a canoe as it's not practical to take my own (I'm in the UK). I want wilderness, not campsite.

I'm also wondering about the best time to go. For work reasons it would need to be between either end of March / early June, or beginning of July / mid October.

I've searched the internet and have some basic ideas (Yukon) but would appreciate more ideas or specific suggestions for trips. I'm not set on Yukon and am happy to look at other areas. I can do 3 weeks for a trip to include travel each way.
