>>197237Longest poratge (not cart trail) I've found was 5305m long Took about 2 hours. You started on opeongo, i assume (talkin about canoe taxis).
As it is, a few longer portages is preferable to many shorter ones, especially if you a) don't feel like getting wet, b) have a lot of loose shit (seriously, pack it down, share bags for gear, and try to have 1 bag/person, of about the same weight) or c) suck at getting motivated at the start of a trail.
The faster you start, the faster you finish.
And portaging- a lot of the shorter ones, you can just hop out of your boat, and walk 'er through the rapids. Pic related.
