Harmony Valley Conservation Area

Love walking doggos here. Lots of side trails to explore and spots to swim. Good for a quiet walk or social time.

We will never go this park again! Most of the dog owners do not keep their dogs on leash in the on-leash areas. In few minutes, three dogs were aggressive to us and their owners did not even care to call their dogs. It looks like this is a dog's park not for humans!

I love taking my dogs on the trails, watching my puppy run and jump you can tell she is living her best life.

This is dog heaven.

A wonderful trail system that gets you from suburbia to fields, woodland and a creek.

My dog gets visibly excited when she knows we're going.

A clean trail with minimal litter.

Great place to let my dog run and get his energy out. Friendly people and lots of dogs to play with.

Great place to let your dog run off leash.mostly contained overall perimeter,
But if you're worried about your pets recall performance, You might want to stay within the fenced area

This is the best place to take your dog for off the leash park. There is plenty of room to run and play
Water to cool off in the hot sun. Lots and lots of dogs. The people that use the off leash area are all really good and helpful. Great place this is a must for your dog to have fun and interact with lots of friendly dogs.

This is coming strictly from a bikers perspective. The trails are by far the best in Oshawa and the near surrounding area. Lots of different areas to ride from single track to a BMX pump track and even a pretty serious BMX jump course. There's a couple pretty sweet downhill trails nothing crazy but fun for the casual rider. My only beef with the area is some of the dogs can be aggressive and chase after you but this is a off leash dog park after all however some people should have some better control of their dogs. But overall it's a pretty nice trail for some casual trail riding or hiking along with a pretty sweet place for BMX riders.

This dog park has gotten a bad rap, a few bad eggs I suppose, it kept us away for a while, until we decided to try it, and we love it, great nature walks, nice people, lots of areas to hang and let dogs interact

I was talking to one staff on counter while the other staff jumped in and said something that I did not what he said, which means they want to help but don’t know how to help. Allow one staff to deal with customers if he needs your help he will ask you. He said something and went inside the kitchen unloading staff which is completely unwanted

Nice spot to get lost. Best if you like dogs. Most extensive mountain biking areas. Joins in to other conservation areas so it's a mutch bigger place than first glance at a map.

If love long nature walks, rivers and dogs. Well this is your place to go! There's a fenced off leash free dog play area, off leash walk area and on leash walking area. It's a dog paradise!

I haven't been here since the late 90s, long before it was converted to a dog park! My pup loved it and was amazing here for his first ever off-leash walk. Looking forward to our next visit.

Nice large dog park, with offleash trails to explore. Note that your dog should have food recall as most off leash areas aren't fenced.

It's just awesome! Love how this is a truly dog friendly area. The dogs can just walk/run freely, there's a creek, hills and ample space for everyone.

Used to be beautiful and safe but have stopped going due to high conflict dogs but higher conflict dog owners, as well as people taking up residence in the park and parking lot. Not feeling as safe as it used to.

Not a friendly area, on the On-leash areas dogs were not leashed. Most of our encounters with the dogs and people were not nice.

Everyone there acts like it's a all off leash area.there is a small area that is but dogs are supposed to be on s leash in most areas.

Love this place. It is a great off leash dog park. You have a couple of trails to take. There is a creek that puddles up to a little pond where the dogs can swim. An open field that's great for dogs to interact and run around and even a fenced in dog park for those dogs that run away.

Long time since the last time my furry friend and I took a walk, but today was just amazing! People super nice, clear paths, poop bags available and more!

Beautiful park for dog leashed, socializing dog, wonderful for walk on woods, trails, lots of green, trees, birds etc.

If you love the nature, you must go and visit this living place. You will just get lost yourself in the sound of woods and water.

Very busy - parking is a tight squeeze. Lots of room for dogs to run. Not as enclosed as we were led to believe. You can keep your dog in a closed in area or hike with them on or off leash.

Really nice trail, lots of mini pathways in it to explore, I literally spent 2 hours in there and there's still more to explore! Love that it leads to a creek, really beautiful
Definitely check it out!

Great place to bring your dogs! Well maintained trails with complimentary doggie bags, and a fenced off area for off-leash dogs.

Great place to bring your dogs. The park has off-leash areas, but in reality people have their dogs off the leash everywhere. As long as your dog is friendly and doesn't jump on people no one will mind. The park also has a fenced in area where you can let your dog off if you're concerned about recall. Great for introducing puppies to socialization as well. I take my dog (Australian Cattle Dog) 5+ times a week to get in the exercise he needs and he always has a great time.

Very nicely maintained trails, though the majority of people do not adhere to the restrictions for off-leash areas. Would absolutely recommend only walking these trails if you are comfortable with getting doggy kisses.

Beautiful trails to walk with an optional closed In area for your puppies! Very large are enclosed and very friendly people! Would highly recommend checking this place out!

What a beautiful place! Have been here several times and each time I visit I'm left if aw. Nature it can't get any more beautiful.

This place was a very unique and special place. A great place to take your dog for a nature walk go for a hiking trails you can see lots of Wildlife the scenery was very beautiful the conservation area was very neat and very tidy also there was lots of parking so you could have easy access to the trails

I usually go in the summer but going in the winter is a nice little treat. It's so beautiful and it gets my pup her exercise and her social needs are met, too!

Excellent off-leash area for dogs, with a massive enclosed area for the ones who aren't so easily called back.
Definitely reccomend

Great mix of dogs very nice trails and enclosed off leash dog park. Not 5 stars because it can be VERY icy in the winter months.

We are so incredibly lucky to have an off-leash dog park like Harmony Valley in our town. I've met people here that have come all the way from Hamilton just to see what it's like.

Wonderful off leash dog park. Many trails and open spaces for dogs to play and socialize. There's also a smaller enclosed space for other dogs.

Its is a great open space, great for hiking with your dog, and family. Off and on leash areas are designated.

Fenced dog area for those who do not have reliable recall, open play area, also.tonnes of trails and beautiful scenery. Readily enjoyable whether your dog is happy to play with others or if you'd prefer to hike with your dog with less dog play

We go to this park almost daily with our puppy. Love the fenced in area so we can let him off leash. The trails are great to walk.

Great place to walk your dog. Lots of off-lease trails along the creek. Parking fills up on weekends.

Love walking our digs here. Only negative is the large number if burrs that hitch rides on the dogs.

The best thing about Oshawa! Huge space, clean, friendly people. Great to vary between open and wooded areas. Great bird watching in the early morning as well.

Great park for the dogus to run around. Few different paths to switch it up. Tucked away from the road

Good easy trails. Creek running through to cool the pooch. Well behaved dogs and so far, people too!

Great place to take dog for a walk. Lots of places to go, and large off leash area for the dogs to really run.

Large area with usually lots of dogs, and people. Nice trails through the woods with a river. Has off-leash areas, and on-leash areas.

Great park with lot of walking trails, this is mainly a off leash dog park so do expect lots of friendly dogs running around.

This is a great place for dogs and their humans to socialize. Beautiful location and lots of room for the doggies to run around and have fun!
