Strawberry Festival coming in Early Summer: Saturdays and Sundays June 15th-23rd. Come join us for the strawberry season to kick off your summer. Our u-pick Strawberries offer fun for the whole family and when you’re done picking, you can grab a bite to eat at Siemer’s Castle Pizza. Free tractor rides to the picking fields on the weekends. Keep an eye on our Facebook page for picking dates and times.
