Great trip to see best of Alsace wine region; traveling from Colmar to Strasbourg over 3 days. A limited number of 21 speed hybrid bikes are available to rent in Colmar. Numerous, significant long climbs on the trip (villages are on the edge of the mountains). Great stops for the night in Ribeauville and Barr. After Heiligenstein the trip is in the flat Rhine river valley.by harv
