A beautiful late winter, early spring hike. we went from the Franklin campground trail to Hidden Lake Trail, out and back about 5 miles total. it was about 6°F and sunny. trails were sometimes snow covered, a few inches deep with ice crust, or cleared to the leaves and pine needles with a few patches if ice.
Walked a lot on ridges through pines and birch forest, and highlight was walking on a ridge between two small frozen lakes.
Bring some birdseed if you're skiing in during the winter. The chickadees and squirrels will love you for it. There's a nice little hut where you can build a fire and make a day of it. I've biked this a few times in the summer (on a 650b) and it's exceptionally bumpy and rooted. I'm looking forward to trying it out this summer on a fat bike, which might make it a bit easier.
Unexpectedly tough trail, but I managed to get through it. I hiked halfway around the loop and stayed overnight at one of the developed campsites. The one I was looking for was not marked well, but with some exploring, I found it. The sites of these lakes weren't anything spectacular, but the hike was fun.
