Where to take a dog near Portland, Oregon: Sandy River Delta

The Sandy River Delta is a sprawling dream of a dog park with "a thousand acres" of trails and plenty of shoreline for your dog and you to explore.

One of the dirt trails with lots of brush to explore.

Located right off Highway 84 about 30 minutes east of Portland, this park makes Troutdale a great place to stop during a road trip to Seattle or beyond.
We stopped here before driving along the Columbia River Gorge and the dog could not have been happier: there were fields to hunt in, plenty of other dogs to play with and lots of water to splash in, as from the park you can access both the Sandy and Columbia rivers.
This park had so much space for all the dogs it was easy to avoid others if your dog is not very friendly, but there are trails on which your dog is expected to be on-leash and it can be confusing to tell when those end and the others begin.
But that was the only drawback to this park I could find, and it is a very minor one. In fact, I liked it so much I immediately wanted to plan another road trip with a stop in Troutdale.
