We left Rudesheim at 7am for the cruise along the Rhine Gorge. There were castles, more than 30 of them over the next three hours. I got photos of all of them but I won't bore you with that here; instead, here is a selection.

Breakfast took longer than normal due to the need to dash off to one side of the boat or other every time another castle hove into view.

After breakfast we mostly stayed at the bow of the boat for the best views.

We arrived in Koblenz at 11am and set off for a walking tour. Our local guide Claudia wasn't as humorous as our previous guides - more German, perhaps? - but she was just as knowledgeable and we learnt a lot about Koblenz which seems a lovely little town. It is built at the confluence of the Rhine and Mosel rivers.

It has a lot of old buildings dating back to the 15th century.

We also spent some time in the oldest church in town which boasted more modern stained glass windows.

The symbol of Koblenz is the "Spitting Boy" statue.

The town square is the venue each year for a giant advent calendar with one of the 24 windows in the roof of this building being opened each day.

Another square has a tall statue that describes the history of the last 2000 years of Koblenz.

After lunch we rode the cable car over the Rhine to the fortress on the top of the hill opposite.

The fortress had huge walls and defences.

But we weren't there for that, we were there to take in the views.

We still had some time before dinner so we borrowed two of the boat's e-bikes and went for a ride along the banks of the river Mosel.

Returning to the boat, we enjoyed a swim in the pool. While we were in the pool, another cruise ship arrived and docked alongside us. The captain was so skillful he was able to manoeuvre his ship alongside and touching us without causing as much as a ripple in the pool.

After dinner, our evening entertainment was a local violinist, Julia, who played a selection of classical and popular songs.
