My wife n I plan to travel through Germany. After chking out train timings, we plan to take the 0800 hrs train from amsterdam to koblenz, spend an hour there, n hop to a KD cruise to baccharach reaching at 1830 hrs. Are the two hours in Koblenz enuf to do a bit of exploring. And i suspect by the time we reach baccharach, it mite get too dark to see any sights on the way. From Baccharach, are there any places of interest so we can come back to baccharach by nightfall ?
