The Trout Derby takes place during Summer 20-21 in [[Cindersap Forest]] near the river below [[Marnie's Ranch]]. It starts at 6:10am and ends at 2am. Players can catch [[Rainbow Trout]] all day long. Each Rainbow Trout caught has a chance to give a Golden Tag, which can be exchanged for prizes.
Unlike other festivals, shops and homes throughout Stardew Valley are not closed on the days of the Trout Derby, and time continues to pass during the festival.
