The Cascade Locks Marine Park is a 23 acre state park in the city of Cascade Locks, Oregon. It features the historic locks built in 1896 where the town got its name. Sure, the community could trace roots earlier than the late 1800s, but this was the time when the settlement was really solidified.

Today, the Cascade Locks Marine Park offers a wide array of recreational activities to its visitors. It has areas for indoor events that could be rented for private gatherings. There are also excursions offered from the Sternwheeler Columbia Gorge. Outdoor areas like a playground and picnic spots can also be found on the site.

The Cascade Locks Marine Park is a part of the National Register of Historic Places.
