Deputy Zack S. Parrish III Memorial Park

The zipline alone is enough to keep kids begging to come back — it’s genuinely one of the better ones you’ll find at a public park in Castle Rock. Beyond that, there’s a solid climbing structure and slides that work for a pretty wide age range, so you’re not just dragging your toddler somewhere your older kid is bored out of their mind. The open grass field gives everyone room to actually run around, which sounds obvious but a lot of parks around here skimp on that. Pack a lunch because the picnic tables and shaded seating make it easy to stay a few hours, and parking and restrooms mean you’re not scrambling.
