My plan is to stay in a base in Rhine/Mosel (cochem is my current choice as I read a number of recommendation on this forum) for 4 nights with a bike or cycling for day trips, and spend the last 5 nights in Amsterdam for museums, shopping and nightlife. We will travel by train therefore I am planning a maximum of 3 base.
I do want to see cologne cathedral, so should I spend 2 nights in cologne? Or is that time better spend elsewhere with just a day trip to cologne.
My husband loves German watches and nature photo taking while I like a bit of everything.
Is there any adventure water activities or nice town with watch museum/tour between this part of Germany to Amsterdam?
Would appreciate advise and suggestion on your preferences of towns to spend the 2 nights.
