Sounds like an adventure! Was that underwater bridge in the last 10K? Between two slabs of rock? If so, it was also partially underwater in August due to high Georgian Bay levels. There’s a photo near the bottom of my report. Apparently there’s a better crossing on the beaver dam beside it but we just got our feet soaked. You must have had chilly toes!
I’ve thought about the 2-day-in-daylight loop too. We haven’t seen much of the west side of the loop in daylight. It seems boring compared to the rest of the loop but it’s not fair to judge a trail that we’ve only seen in the dark.
There is a complication in doing a 2-day loop. The online park reservation system thinks that is too far to hike. But if you phone the reservation number and talk to a human, maybe they could be convinced. At this time of year, I think the sites are non-reservable so you can just hike till you find one.
Yeah toes were cold especially because the second half has a lot less mountains to climb up so more of the trail was under water. That's the bridge we're talking about it looks a lot less ominous in your photo than when we got there. Middle of the night and the whole thing was under about a foot of water.
Brrr! You hit it at the time of night when it felt cold even in August. That last part seems to go on *forever*.
