North of Loon Lake we found 395 to be reasonable and enjoyable. South of Loon Lake it is getting busy and unpleasant. This route leaves 395 a few miles south of Loon Lake. The riding is quite enjoyable. There are a few short steep hills at the south end of Swenson Road. We were told by a local cyclist the few miles on 291 can be hazardous during commuting hours, but we found it acceptable on a Sunday afternoon. It is highly recommended to cross the river near nine mile dam as shown to get on the Spokane River Centennial Trail, which is fantastic, a real jewel. This section ends at a dirt trail that takes you to a foot bridge that crosses the river to the Bowl and Pitcher park. The final 100 feet of the bridge approach on the west side is quite difficult walking with a loaded touring bike, unfortunately the recent "improvements" were done without apparent consideration for cyclist. We were less than impressed with the campground, it was expensive and crowded, but that's city living for you. Following this section I recommend crossing the bridge to the west side again and continuing south on the Spokane River Centennial Trail.
I will post some other recommended bits on the route to Missoula as I have time.
