While the North Shore rivers of Minnesota are great places for expert paddlers, most of them can be deadly for non-experts. The lower Baptism is no exception; it's winding, steep, and twisting, with class IV and V waters.
Be prepared before you go with shoes like these from Columbia, that can handle the water or the slippery rocks when you portage. Another good choice is these convertible pants from Merrell. Wear as shorts while you're in the water, and zip on the quick-dry bottoms to save your knees from scrapes when you're out.
You'll hit action right after you reach the dells. There are two offset holes that you can avoid with little trouble, then a sweet pool at the end where the river makes a sharp left turn. Below that, another rapid leads to a boulder that splits the flow. The left side is your best bet, but if you can handle the Baptism, you'll manage the right.
There are a few sharp drops ahead, including one ledge that's about 3 feet and also shoots you off to the left. Past that, get ready to get out (river left) and scout. Downstream from you is Illgen Falls, a 35-footer. It has been run, usually with only minor problems, and you'll probably pop right up from the churning froth at the bottom. Then portage around it (also river left) to a steep trail, and it's not easy to climb down carrying your kayak, but wiser heads usually take the portage route. Below that, be ready to go ashore (river left) to avoid hitting a footbridge and going down High Falls just beyond. High Falls is the highest waterfall in Minnesota, and you'd have to be crazy to try it. Carry the kayak, take the trail, and put in below.
There's plenty more to come, but don't try this river without a good guidebook (try "Paddling Minnesota" by Greg Breining). The lower Baptism is sure to give you more than one rush!
