I was hoping to find current river conditions, but this thread seems to have deviated a lot from the subject.
We leave a week from today for our Viking "Paris to the Swiss Alps" excursion. We're cruising from Basel to Trier on the Rhine and Moselle. Hopefully, the water will be decent. We cruised Viking's Grand European in 2019 and the water levels were very high. We barely got through the bridges with the sun deck down almost the entire trip.
I'm also concerned about a Germany transit strike, for any coach trips, but it looks like it was just yesterday. https://nypost.com/2023/03/27/strike-over-pay-paralyzes-rail-air-travel-in-germany/
