Purchase a ticket and join the crowds at a game at Werk Arena. If there's nothing happening while you're there, you might like to check if the stadium offers a guided tour of the grounds.
This sporting facility is on the to-do lists of many travelers to Trinec. But Werk Arena isn't the area's only drawcard. T. G. Masaryk Square, Gora Zamkowa, and Tesin Theatre are some other interesting attractions nearby.
