Admission fee varies. Normally when the park is open during the summer, it is $6 per person, children under 12 are free. During special events it is higher. $15 for the Great Oregon Steam Up. $10 for the Truck Show. $22 for Hops and Vines. There are multiple other events throughout the year, and each sets their own admission fee, so check the calendar before you go.
