This is where I spent any day I wasn't working in the summer's before moving to Missoula. This is a great place to climb, the basalt is excellent and there are some pretty fun routes for trad or top rope. It doesn't get much better than climbing right along the river.
Taylors Falls has many great climbs, it does get busy on the weekends. Have a good understanding of anchor building and have a nut set and lots and lots of webbing at the very minimum. If you climb by the wood lookout you can work it's base into part of your anchors.
Good climbing, close to the cities.
My home crag. Short routes, but lots of variety. Can be crowded, but the St. Croix River valley setting makes it worth a visit.
