Harmony Valley Park and Off-Leash Dog Park

Harmony Valley Park and Off-Leash Dog Park is a large natural green space in Oshawa, part of the Durham Region, known for its scenic trails, open fields, creek, and abundant wildlife. Within the broader Harmony Valley Conservation Area, the off-leash dog park provides about 25 acres of space where dogs can run, play, and socialize freely under voice control, with both open fields and a fully enclosed fenced area for secure off-leash fun. The park’s mix of trails and natural landscapes makes it a popular destination for dog owners and outdoor enthusiasts alike, blending passive recreational opportunities with a relaxed, community-oriented atmosphere. It’s maintained with the help of volunteers and offers a great way to enjoy nature with your furry companion.
