Tom Diana Park at Granite Knolls Recreation & Sports Complex

Constructed on 15 acres of the 125 acre Granite Knolls Park (West) the Granite Knolls Sports Complex has two full-size multi-purpose fields, a baseball field with press box and bleachers, a snack bar, restrooms, picnic area, basketball courts, pickleball courts, a pavilion, and parking facilities. The park is connected to Sylvan Glen Park Preserve by a trailway.

On March 25, 2022, the Town held a ground breaking ceremony for an Inclusive Playground to be constructed next to the pavilion that will allow children of all abilities the chance to play together. Phase 2 of this project is the installation of a Sensory Garden immediately adjacent to the playground. The vision for the garden project is to create a space where Veterans and seniors can find solace and tranquility. Inspire our community to "stop and smell the roses". Our one of a kind enclosure for the Inclusive Playground will allow children to explore their senses through site, sound, smell and touch. Click the link below for more information and to donate to the playground and garden projects. On Saturday, June 18, 2022, the Town will hold a grand opening and ribbon cutting for the Inclusive Playground.

On June 8, 2024, the Park was renamed in honor of former Yorktown Supervisor Tom Diana, who passed away unexpectedly on January 5, 2024 just days after he was sworn into office for his first full term in office. Supervisor Diana had been a councilman on the Town Board since 2015 and a third generation Yorktown resident.
