The Tatras, with an emphasis on athletic, healthy living, is alas no place to party. The bar at the Grand Hotel in Starý Smokovec occasionally books live entertainment in the evenings, so check with the front desk to see what's on. Otherwise, enjoy a slow meal, take a stroll around the town, and then fall asleep with a good book (that's why you came here in the first place).
