Mercurio Tours provides very reasonably-priced guided-tours in Germany and Austria, traveling along rivers such the Danube, the Rhine and the Moselle. These regions provide excellent cycle paths (we are fans of any tour that has minimal traffic!) and numerous possibilities to soak up local culture and traditions. Each group is limited to about 12 cyclists, and is accompanied by two experienced and bilingual guides. Accommodations are mostly family run hotels or guesthouses, and meals are included. The prices are truly amazing ... much lower than comparable tours from U.S. based operators. A couple things that differentiates them from other Germany-based tour groups: Airport transfers included (this is HUGE ... if you have ever had to pay major $ getting to a small town to start a tour you know how important this is), guarantee of English-speaking guides, and flexibility in meal choices at restaurants along the way (another big plus ... group prix-fixe is often less than appetizing). Daily mileage tends to be quite low (20-25 miles) as the tour also focuses on the cultural aspects of each region.
