I have read previous posts in regards to this topic, I just wanted to get some some facts straight.
It is recommended to take the slower which is more scenic route that goes throught the Middle Rhine Valley then on the way back from Cologne to Frankfurt take the fast highspeed link.
I have looked at DB Bahn timetable, and I am assumming the Slower route people referred to from Frankturt to Cologne is the one taking approx. 2:30? with stops or no stops? and faster route would be the one taking approx. 1:10?
Since will be spending one day in Cologne, we wanted to maximaze the time there. So, is the route with the beautiful scenery really a "must do"? Would you be able to get off if taking transfers/stops to really enjoy the scenery?
Thank you in advance for your honest opinions.
