From the parking area drop down about 7 feet to the marshes and wetlands. Walk along the North-South Trail which can be flooded in spring. You’ll pass the Northwest Pond and the Oak Island Pond. The trail here is an old service road which heads south through the wetlands.

The wetlands have been used for several purposes over the decades. They were ditched and drained for farming and cattle grazing. The wetlands were used over time for disposal of cannery wastes and construction debris. After World War II the city started farming in the area and in the 1970’s public interest increased to restore the wetlands and create a wildlife preserve. In 1997 the Jackson Bottom Wetlands Preserve Board was created and now the area is managed by the City of Hillsboro Parks & Recreation Department.

After about 0.5 mile is a series of pipes and valves for irrigation which are used to pump water from the Tualatin River. You can explore the tangle of pipes and valves and try to puzzle where the pipes go.

Continue along to a bird blind on the left overlooking Wapato Marsh. Anywhere along here you should see a variety of birds. This is just about in the middle of the marsh and is mostly away from the traffic sounds. Though it was a mid-June afternoon for this review the flies and mosquitoes weren’t noticeable. That might be a different story later in the evening. There is a lot of standing water in this wetland.

The trail changes from dirt and gravel to wood chips which can be quite soggy after heavy rains. Soon you come to an osprey nest atop an old power pole. You may see the ospreys tending the nest and the fledglings. The nest is pretty close to the trail. As with all nests you should stay on the trail and not make motions that disturb the birds.

At one point along the trail there is a small sandbox for toddlers to play in.

Stay on the main trail to the junction with the Pintail Loop Trail. This is a nice walk past a shady shelter around Pintail Pond. There have been log structures added to the shoreline to provide places for birds to perch away from the trail.

There are additional trail options to explore such as the trail to Salamander Slough and to the visitor center.

Return to the North-South Trail and make your way back to the parking lot.

This is a great hike for kids with wide flat trails and some bird blinds where you can watch the different birds.
