Merrill Park is a 182-acre public facility in Colonia, New Jersey, operated by the Middlesex County Department of Parks and Recreation. It features multiple sports fields, including baseball diamonds, softball fields, and tennis courts. A focal point of the park is its dedicated animal haven, which houses a variety of species for public viewing. The grounds are integrated with the South Branch of the Rahway River, which runs through the park's eastern section. Visitors have access to numerous picnic groves equipped with grills and tables. Paved and wooded walking paths traverse the park, connecting play areas to the more naturalized sections. The facility serves as a primary community hub for organized youth and adult recreational leagues in the Woodbridge area.
The scenic bridge crossing the Rahway River provides the best vantage point for landscape photography.
Visit the animal haven early in the day when the animals are most active and visible.

Bring bug spray if you plan on using the wooded walking trails during the warmer summer months.
Do not attempt to feed any animals at the park as it is prohibited for their health and safety.
Leash laws are strictly enforced for pets; dispose of all waste in provided receptacles to maintain park hygiene.
