Portage Trail

General description: The first 100m is level, the next 1400m is a constant elevation change. One must constantly be on vigil because the first 1000m of this portage is composed of mainly rocks and roots. The last 500m is a nice smooth path that ends at the campsite at Erables Lake. Overall, a challenging portage.

A note about the campsite: The campsite is the haulage area. Thou not a large site, there is room and sufficient level area for several tents to be set up.

Topographical impediments to travelling: The rocks and roots are so predominant on the first 1000m of this trail, that you must constantly watch where you are placing your feet. Failure to do so, could result in a twisted ankle or worse.

Areas susceptible to impact by periods of rain or beaver flooding: None noticed.
