Best Trips?

Wonderland Trail around Mt. Rainier. Obviously not outside US, but gorgeous. Pristine camps. Reservations begin in March, I think.

You could try the Kungsleden in Sweden. The southern portion is supposed to be quite easy to get to.

Or you could walk across Scotland. Sublime!

great idea's guys, thanks

Fly into Jackson hole.
Take a cab to the northern entrance of yellowstone.
Hike back to the airport. Through the west side of yellowstone and the Tetons.

edit; Didn't see the outside the US thing. Only a week out of the country? how many travel days will you have?

There are some good trails in Ontario, Canada. You could do a 100 mile loop on the Western Highlands trail in Algonquin Provincial Park. I think there are some other trails further north in Ontario that are even more remote and IMO even better (although I do love algonquin). The Le Cloche Silhouette trail in Killarney is awesome but only 50-60 miles. I forget the name of the park, but another park further north has a longer loop.

Dan – there are two trails in Algonquin from Hwy 60. One is the Highlands trail but I think the one you are referring to is the Western Uplands on the north side of Hwy 60. It's a great trail with multiple loop options but as Dan says not so remote. Being about a 3 hour drive from Toronto means that it can get busy at times.

There is a trail in Lake Superior Provincial Park but I am not sure if it is still in use. There is a trail at Pukaskwa National Park but it is a short one in comparison at 60 km.
