From December 5-20, Knott's Berry Farm is offering free or discounted admission to anyone donating toys to the U.S. Marine Corps Reserve's Toys for Tots drive.

To qualify for a free ticket, guests can either buy a $15 gift through the Knott's Berry Farm website, or spend at least $15 on a gift from one of the Knott's Marketplace stores near the park's main entrance.

Alternatively, guests can bring their own gift (unwrapped and valued at $15 or more) to receive a voucher allowing admission at the reduced rate of $15 (a discount of $37.99 for adults and $8.99 for children).

The U.S. Marine Corps Reserve will distribute the donated toys to children throughout Southern California.
