We are planning a trip to Zagreb in December. We expect to stay for between 3 and 7 days before moving on by train to Prague via Vienna. We plan to rent an apartment/hotel in Zagreb, and we won't have a car. Aside from the usual- exploring the old town, checking out the markets, etc, what can you recommend for Zagreb in Dec? We read that Mount Medvedica is accessible by tram from Zagreb. Is it worth a trip for two non-skiers in Dec? What can we expect the weather to be like? (We are from the Canadian prairies, so we are used to cold.) Is there anything special we should think about considering we are going at this strange time of year? We know the coast would make more sense, but we must go to Prague for a week to 10 days and don't think we can squeeze the coast and Prague in in this time.
