This is beautiful and a good reminder of the gorgeous places all around us in Duluth...Lester River trail is pretty too and would look good in a video.

The Knowlton is a great sugguestion.  If you hit Lincon Park remember to go up the trails to upper part below Skyline.  That is a nice short to midsized trail with a few great falls.

Some urban seplunking in the tunnels of Chester Creek from Fourth Street down is always interesting. Bring hip waders, a flashlight and don't go if it has rained at any point 24 hours earlier.
