I had been wondering about Wonder Lk. for a few years; finally, late this September, I dedicated a solo daytrip to check it out. The day was one of those glorious northern MN fall days: sun, light breeze, low humidity (I think?), fall colors etc. I put in on Sawbill around noon. It was quite busy in the parking lot and at the landing, but quiet once I got out on the lake. Didn't run into anyone on the highway to Alton, but all 4 sites I passed were occupied. I arrived at the portage to Wonder around 1:30. The way the sun shone on the portage entrance through the cedars made it look like a gateway to Heaven. I had read a couple reports that stated the portage was overgrown and that Wonder Lk is seldom used, so I set out to hike the portage without my canoe. While there were some slightly overgrown spots, the trail was very easy to follow and of course by the time I got to Wonder I regretted not having the canoe! I took a few steps into the water, soaked in what I could see of the lake, told myself I'd have to return next season with the canoe, and hiked back to Alton. I ate my lunch and drank my wine while floating on Alton listening to the loons. I'm always amazed at how much enjoyment and adventure a person can have in a 4 hour daytrip!
