West Hills Park stretches across 7.5 acres on Santee's Mast Boulevard, anchoring the eastern corridor with a sensory-designed playground, a sand volleyball court, ball fields, and a large covered gazebo near West Hills High School. The sensory playground features rubberized surfacing, inclusive play structures, and toddler-specific equipment that serves the same early-childhood demographic enrolled at BunnyBears Preschool Santee. Barbecue grills and picnic tables line the gazebo area for group gatherings, while a separate gated toddler zone keeps younger children visible from the surrounding benches. Mast Boulevard's ball-field users cap tournament days with post-game meals along the corridor, where Deano's Pub East on Woodside Avenue pours drafts for the adult league crowd. The park sits adjacent to the Mast Park trail system, placing it within a connected greenway that links eastern Santee's residential neighborhoods to the Carlton Hills recreation zone.
