Is the park fully fenced?

Mostly, but not everywhere. Posted signs mark the unfenced stretches, which is part of why reliable recall matters here.

The Sammamish River runs the length of the park with several access points for wading and swimming.

Is there shade on hot days?

The tree line along the river shades much of that stretch, while the open meadows have little cover.

Does it work for small dogs?

Small dogs are welcome, but some sections have tall grass and dense bushes that can hide a little dog, so keep them in sight.

About this park

Marymoor Off-Leash Dog Park in Redmond is one of the largest and most beloved off-leash areas in the entire Seattle metro, covering 40 acres of open meadows, woodlands, and river access along the Sammamish River. Dogs run free across open spaces, splash in the water, and follow wide natural trails, while herons nest in nearby trees. A volunteer organization (SODA) helps maintain the grounds.

Before you go

Parking is $1 and requires either cash or a downloaded app; bring both options. The park is best suited for dogs with reliable recall; reviewers strongly caution against bringing reactive dogs or dogs that aren't reliably trained to come when called.
