There is a beautiful two days tour along the river IJssel (19 and 13 km). You start in Zutphen, walk to Deventer along the Westbank of the river, stay over in At the foot of The Hill, and the next day you continue your walk to Olst. There are trainstations both in Zuthpen and Olst. Click for all information and downloading of maps here.
Another possibility ands also very beautiful, but a little longer (24,4 and 19 km) is the following: You start in Zutphen and walk to Deventer along the Eastbank of the river, through a very diverse landscape. You stay the night in At the foot of The Hill and the next day you walk back to Zutphen along the Westbank of the river. I have maps and gps-files which I can send to you.
