European group tours that allow you the flexibility to move at your own pace. The tour takes a minimum of 18 days to complete, but if you want, you can stop for a few days and pick up with another group and continue as you choose. Groups are scheduled to pass the major stops along the route every three days. Most of the travel is by rail, some is by boat or bus. Rates do not include meals or accommodation, however the guide can make accommodation arrangments.
Shorter segments are also available.
