Free things to do with kids in Half Moon Bay

An inclusive playground with three separate structures sized by age: toddlers, little kids and big kids each get their own zone.

A toddler-scaled climbing playground with an elevated crawl tunnel, a small rock wall and cork surfacing, and no swings by design: every piece builds climbing.

Established in 1932, the patch for kids who want a challenge: a two-acre hay maze, a cornfield, a haunted barn, plus a train, pony rides and a petting zoo.

The quiet, pumpkin-first stop: rows of every variety from tiny gourds to 250-pound Atlantics, a hay ride out to the field, and a vintage tractor for photos. No rides, no crowds, dogs welcome.

Calm harbor sand for digging, with boats coming and going to watch from the path, and no big waves.
