The Forest Opera is a wonderful open-air arena set in a hollow in the forests surrounding the city in a western district of Sopot. With a history going back to 1909, the theatre has seen everything from German opera to Whitney Houston performances and has hosted the Sopot Song Festival in various guises since 1964. A rebuilding programme between 2009 and 2012 now sees this unique location integrated with 21st-century facilities and one of the best sound and vision systems in Europe. The Forest Opera is also a good starting point for a number of forest walks, one of which leads into Sopot, another to a splendid viewing point overlooking the bay.
You'll find it a 10-15 minute walk from Bohaterów Monte Cassino, though it is a steady uphill route all the way there. Walk up Monte Cassino, passing under the railway line and the main road before carrying on along ul. 1-go Maja to the end. Next, there is a pathway going up with Hotel Opera on your left, which will bring you to the main gate. Allow yourself at least 30 minutes to get to your seat from Bohaterów Monte Cassino on a busy night.
The city's Forest Opera can be contacted directly or refer to BART in regards to events and concerts. Also, be aware that the site listed here is the official site of the Forest Opera as there are a few unofficial ones out there!
