The Monte Rio Recreation and Park District hosts events at the Koret Community Center and the Monte Rio Amphitheater as the Lower River's showcase for a variety of events. The center has a capacity of 100 indoors/120 outdoors, a meeting room, professional catering kitchen, backyard patio and adjoining playground. 

The amphitheater stage area for larger capacity  outdoor seating is surrounded by tall redwoods creating the perfect natural theater under the stars. Sloped lawn seating is bordered by an accessible path to the front for V.I.P. events.  Wedding ceremonies are held at a historical spot behind the stage house, enclosed by redwood trees and the sounds of the creek. 

A path runs adjacent to the Tennis and Basketball Courts and the Parkside Community Garden and the popular pickleball court.

The Amphitheater is home to the Monte Rio Variety Show which has come to define the spot. For more than 100 years the annual musical variety show has generated funds that assist local schools, churches and Fire District.

The Amphitheater has also been the site for all types of events such as Picnic Under the Stars, Music in the Park, Women’s Weekend Festival, RIOFEST Autumn Fair and various other fundraisers and craft fairs.
