    best off leash dog space ever

    we absolutely love marymoor park. my 7 month vizsla is able to run across acres of land playing fetch and chase with so many other friendly dogs. we've been able to arrange vizsla meet-ups here as well which is a fantastic way to make puppy and human friends! we probably spend about 3-4 hours here at a time. parking is easy, costs $1 for the day. there is also a pet washing station right outside the park, so on the rainy/after rain days when there is a lot of mud this is a nice amenity before hopping back into the car.

    Best time at this park!

    I drove out to Seattle with my dog, Bode, to pick up my BFF and his dog to drive drive back to Michigan. While there, we visited this park and the dogs and we thought wed landed in dog heaven! So awesome, we stayed an extra night and took the dogs the next morning before heading back! Everyone was friendly and respectful and the park was CLEAN, with poop bag stations everywhere! A MUST to visit!

    this place is great

    Huge area, water and swimming access, shade, open fields. All you can ask for in a dog park. Does have a $1 parking fee.

    our favorite

    Huge. Fields, trails, waterfront access. Make sure you can control your dog because fences mark the boundaries but don't necessarily keep pup in. This is our favorite place to go. Great environment, great dogs, great humans.

    Dog Heaven!

    We live nearby, so Marymoor off-leash is our home park! We go at least once a week. Our dog loves to swim. He has so much fun saying hi to all the other dogs and swimming. People are friendly. There are paths to walk, a tall grass area where I love to let him run! It is a very large area. I make sure when we go, that I budget plenty of time to wear him out before trying to call him back in. Also - and this is the kicker - they have a dog wash! It's called Wash Spot and I used it every time. The guys who run it are super nice and helpful. We leave Marymoor clean, happy, and tired! Very satisfying and we are grateful to be so fortunate to have a lovely place to call home!

    BEST Off-Leash Dog Park in the World

    I have been to dozens all over the US, and this one is the biggest (40 acres!!), and the best. It has water access for swimming dogs, high brush for hunters, open spaces for running after frisbees, lots of extra dog poop bags, a special more protected place for smaller or more timid dogs. If humans got along as well as the dogs in this park do, we'd have a much better world.

    Wish we had one of these closer to home

    This park is huge and is always busy (good luck finding a parking spot on a sunny Saturday). I took Jack here when he was 3 months old and needed socialization. It was a great experience for both of us. A strong recall is a Must at this park as is being relatively well socialized. Your dog will meet dogs of every breed and temperament. Best part about it is that its large enough that if your dog doesn't like that dog over there you can just walk away and play somewhere else.

    Marymoor Park

    At 40 acres, the off leash area of Marymoor Park is bigger than most city parks in total. Marymoor is, without question, the finest dog park in the country. The area is left mostly natural, except for the extensive trail system, which would add up to a good 2-3 miles if you covered them all. The fields are not mown. By mid summer the grass is tall, much appreciated by the dogs bouncing through it. There are woods too, and blackberry bushes for a fall treat. One of the trails borders the Sammamish Slough (actually a lovely river connecting Lake Sammamish to Lake Washington.) Along this trail are four access points to the water, all nicely designed with easy steps down to a shallow wading area, definitely a favorite with the dogs all year, and their owners in the heat of summer. One caution though, it’s not a place for out of control dogs. If your dog does not respond to your recall, you’ll loose it in an instant. The park is that huge. Although ostensibly fenced, the split-rail fence merely defines the off leash area. My small terrier can easily vault it. Make sure you can control your dog before considering a visit
