Having grown up in Wisconsin I would visit the St Croix Falls side frequently. Swimming and hiking the bluff many an afternoon. Now that I live in Minnesota, I find myself frequenting the Taylors Falls side. Here you have the amazing "Pot Holes" from glacial waters and some pretty spectacular rock climbing. My son does that, I belay and cringe from the bottom! No papers need to be shown when crossing the border and a visit to either side of the beautiful St Croix River is well worth the trip! Not far from the MN side is a lovely sculpture park in Franconia - check it out should you find yourself in this part of the state - both are well worth the visit and the sculpture park is FREE!
