Planning my summer trip with my friend and we talked about Belgium as a possibility. We love history, architecture, food and wine. How much time is needed in Belgium? Have just started looking but so far see that Brugge, Brussels, Antwerpen are the spots to hit. We like to stick to train travel....ok for getting around there? Any smaller areas to hit? We have 10-12 days...time for any side trips to say Amsterdam or Germany? I know nothing about Cologne but would love readers opinions on a fun itinerary for us! I thank you in advance for taking the time to read and comment. Appreciate the help!
