Paved paths lead from Cook Park, through wetland areas and over the Tualatin River to connect to Tualatin Community Park.
Much of this trail is not constructed yet, but when complete this important piece of the 40 Mile Loop trail system will provide an over 21 mile east-west link along the Columbia Slough -- connecting Blue Lake Regional Park in Gresham to Kelly Point Park in North Portland. The built segments of the trail pass by Delta Park between North Portland Road and Interstate 5 on the west end and also along the slough adjacent Airport Way on the east end.
The Clackamas River Trail was completed in 2004. The approximately one-mile trail runs through the Clackamette Cove area from the Main Street Extension to Washington Street, which connects to the footbridge to Gladstone.
The six-mile Chinook Trail connects Tarbell Trail with the peak of Silver Star Mountain. It bears the name of the trail that hopefully will one day encircle the Columbia River Gorge. The Chinook Trail is open for hikers, horseback riders and mountain bikers. The first two miles are flat and forested and then the trail reaches an open meadow. At the four-mile mark, the Chinook trail splits from Tarbell to the left along an abandoned road. Chinook trail reaches the ridge of Silver Star Mountain and Ed's trail.
A four-mile bicycle trail begins in the Riverside Day-use Area, winds through meadows and along the river bank and ends at the park's Historic Butteville Store (open seasonally). A one mile hiking trail loops off the bike trail between the Pioneer Mothers cabin and Oak Grove Day-use Area, passing the park's historic townsite.
