Across the river from Stalin Park is Sun Island Park, a 38-sq-km recreational zone with landscaped gardens, a ‘water world’, a ‘Russian-style’ town, and various small galleries and museums. It’s a pleasant place to have a picnic, walk or bike (¥60 per hour), though as usual you need to pay extra to get into many areas (too kitsch and not worth the money in our opinion).
Boat across (¥10 return) depart from one of many docks just north of the Flood Control Monument, or catch the nearby cable car.
