On the south side of the river, you can explore trails in the west La Center bottom lands.  During the right season, this is a good area to observe waterfowl, including a large flock of swans (from a distance) who winter there.  While the trail to the west is clear for less than half a mile, it does open interesting areas to explore.  I followed deer paths for another 1/2 mile.  It is interesting to explore some of the deer paths and beaver trails through this area.
