  Directions

The name says is all! Literally a thousand acres of off leash trails that lead to the sandy river where your dog can wade or swim. You can walk around for hours or just a little while, either way you and your dog will love it. It can be muddy at times due to Portland's frequent rain, but there is a main gravel trail that is ok for walking on even when its wet out. Take I-84 to exit 18, follow the road and cut back under 84, stay straight instead of getting on the on ramp and you will be in doggy heaven!

  Great Place to Run Free

  While visiting our grandkids, we needed a place to play with our 6 month old pup. The Sandy River Delta was perfect. Our grandkids taught the pup to retrieve a frisbee. There is so much room to run without watching for traffic. All of the other dogs and their owners were friendly. We will go back before we return home to So Cal.

  great!

  This is by far one of the best dog beaches out there. It's a long walk to the beach but I love all the different trails getting there.

  The river was great, shallow and perfect for ball chasing etc.

  Bring lots of water!!!!

  Great Place

  This is a great place to let your dog run and play. Many trails and most of the park is off leash.

  Awesome

  This place is great for exploring. The only down side is that you can get lost easily. Not many clearly marked trails in the wooded areas, but that is half the fun. My dog loves it here.

  Please follow the (very few) rules.

  The place is amazing. But please follow the few rules: on leash in the parking area and on the confluence trail (that main gravel one in the description). And of course pick up and carry your poop away. Enjoy!

  Lots of Trails

  Beautiful surroundings! Availability of garbage cans makes for shorter times that you're carrying poop bags!

  amazing!!

  We love taking the dogs here! Even on a busy day you can take a trail out and be alone with your puppies or head to the river for some play time with other dogs! This place is huge!

  my dog loved it

  This was a fantastic hike with my dog & husband. We just moved here and a local was kind enough to show us the way to the river where my dog & her (very nice) dog played! For being a no leash park all the dogs seemed to b well behaved & non aggressive. Did have to go through water at times this time of year to get to the river. But overall we loved this park and I will go often as we can! If u have nice dogs highly recommend!!
