We are planning on taking a driving tour of the Mosel Valley from Trier to Koblenz. Any suggestions that would be helpful? Places to stay, things to see etc.
Thanks

Hannah, we did this drive many years ago so I can't remember exactly where we stayed but I wanted to tell you that you'll have a lovely time. We liked the Mosel much better than the Rhine. If possible, go in the fall when wine festivals are held. The locals prefer sweeter wine than North Americans are used to drinking. They call dry wine sour. Trier is worth a stop for the historical connections and you will find lots of attractive villages that need a closer look. Berncastle was one of my favourite villages and I still order Berncastle wine whenever I see it.

We returned three days ago from our trip in Germany. Mosel Valley is beautiful!
We stayed in Cochem, that was recommended here in Fodor's forum. We love Cochem. We stayed in old city, in Pension Albers, and we were very happy with this. We had a bedroom, a saloon plus a small kitchen, bathroom. This was 45 euro / night. There is elevator. For breakfast we payed 5 euro / pp.
From Cochem we made trips to Koblenz, Beilstein, Burg Eltz, Trier and Luxembourg.
We had no car, we use the train.

Trier is a fine place to start: while there, do not miss Constantine's Basilica. When driving down the Mosel Valley, just pull over when anything takes your eye. I'll bet you stop often! We stayed at a village called Mehring, simply because it was the next: a perfectly splendid place to sit on the hotel terrace, have a fine meal, and watch the water traffic go past on the river. There's also the significant remains of a large Roman villa within walking distance.However, all the villages have their own attraction, so don't hurry.
Now here's some really good advice: when you reach Koblenz, cross the Rhine, and drive down the Lahn Valley through Bad Ems at least as far as Nassau. The Lahn River is much smaller than the Mosel, but very attractive, and Bad Ems is sensational. It's a short drive, and worth considering.

We toured the Mosel and part of the Rhine in 2004 and agree with moolyn that the Mosel is much nicer than the Rhine. I will check my guidebooks when I go home tonight, because we found a fabulous wine-oriented guidebook that we used for our trip. It's definitely worth getting recommendations for wineries because, although some Mosel wines are wonderful, a lot of them are mediocre - along the lines of Blue Nun.

We booked a hotel for our first night (a castle north of the Mosel) and our last night, but just asked around in villages for the other 3 nights.

It's a great place to bicycle, too, because there is a wide, flat bikepath along the river. If one of you likes challenging rides and the other prefers the flats, the mountain biker can ride up the hillsides and bomb back down again while the other one pootles along beside the river.
