We were camped on a beach site close to the 485 m portage into lost dog. Did a day trip paddling to the 1900m into Lorne lake, then paddling/portaging through Lorne, Sisco,Lost Dog. To our delight both longer portages were downhill, shorter ones uphill but not bad. Easy to do in one day, I’m older therefore slower so younger people should be able to do it in maybe an afternoon.
