Twin Bridge Park is a 27-acre family-friendly town park in Merrimack's Town Center, offering wooded brook-side trails, Little League baseball, basketball, and picnic areas. The star attraction for families is the Kids Kove playground. Kids Kove is a large, multi-level wooden castle structure with distinct zones for toddlers and older kids. The younger children's side includes crawl steps, a tunnel, a small bridge, tiny monkey bars, and bucket swings, while the older kids' side offers slides and standard swings. The whole structure has been updated with splinter-free composite decking, inclusive ramps, and accessible swings, plus a small sandbox. The castle's many levels and hidden nooks are great for imaginative play, though they can make it tricky to keep tabs on wandering little ones. The playground is fenced with a ramp entrance and a short downhill walk from the parking lot. Shade is sparse, so bring water and snacks. Seasonal portable restrooms are available on site.
