I do alot of my riding around the lakes. Harriet and Calhoun seem to be the best that I've seen. The trails are nice and smooth, and they have a one way trail dedicated to bikes and roller bladers. I went up around lake of the isles one time, and the trails were really choppy and needed to be repaved. The great thing about living in Minneapolis, is that I can just hop on the trail, and it's about 2 miles from my house to Harriet. I can make a few laps and then head back. I don't have to load up the bike, drive there etc. I'm just a few blocks from Minnehaha (sp?) creek, so it works out pretty nice. If you get a nice day, there's usually some good "scenery" on the trails too.
