Djrashkharh (Waterworld) is a big waterpark located on the outskirts of downtown Yerevan on Myasnikian Street.
The park usually opens in late May or early June, and closes the season at the end of September or early October.
Right next to the outdoor park is the non-smoking indoor waterpark. The complex is open year-round and includes a large swimming pool, Turkish bath-house, jacuzzis and more.
