One fine Sunday morning, we took the train two hours west from Prague to Karlovy Vary (Carlsbad, as the Germans call it), a spa town made famous during the 16th century and whose 18th and 19th century architecture make it a place definitely worth visiting. Its a small but wonderfully preserved city, the perfect place for a weekend getaway. From the small train station, which sits above the city, it's an easy 1-mile walk down and across the bridge to the city center.
