I'll clarify a bit if I can. The last time I went through there about 2 or 3 years ago, the park had relocated the bog trot portage to the western side of the bog. I paddled carefully through the bog, on  the western side to the northern end of the cliff face. At that point, I was able to take out on a narrow, flat landing and follow a new trail cut into the woods, the trail I followed met up with the old trail at a turn in the old path, just after it climbs out and heads north away from the bog.

It would be interesting to head in that way and see if that new trail is still in service.
