Trojan Site and Prescott Beach County Park

Stay Safe

In Oregon, a bicycle is legally considered a vehicle, and the same Oregon road laws apply. Please “be seen” and practice safe riding. Vehicle traffic, farm equipment and narrow shoulders exist on many Oregon roads, and you may find that construction projects, traffic or other events may cause road conditions or signage to differ from the map results, ride descriptions and directions. For travel options plus weather and road conditions, visit, call 511 (in Oregon only), 800.977.6368 or 503.588.2941. Routes listed on this website are for informational purposes and intended as a reference guide only.

This former nuclear power plant site still has a park with a pleasant lake, picnic shelters and restrooms maintained by Portland General Electric. Peregrine Falcons nested on the Trojan cooling tower, which used to loom 500 ft above the park before it was demolished in 2006; the falcons are still seen now and then. A flock of domestic geese will certainly greet you. However the best birding is to the N of the park at the Carr Slough wetlands. Either hike along the dike that starts from the NE corner of a large reservoir N of the entrance road, or drive N 0.7 mi on Hwy 30 to Graham Rd. This road is elevated with good views of the wetlands on either side of the road. Waterfowl are abundant in the winter. At the end of Graham Rd, check Prescott Beach County Park for wintering gulls and scaup flocks on the Columbia River, and Caspian Tern during spring and summer. This park charges a day-use fee of $3 per vehicle; entrance to the Trojan site is free.

The Trojan site is at MP 41.5 on US Hwy 30, which is 4.5 mi S of Rainier and 12 mi N of St. Helens. GPS 4602.161 N, 122 53.618 W. Prescott Beach County Park is at the end of Graham Rd, which is 0.7 mi N of the Trojan site on US Hwy 30. Then follow signs 0.6 mi to park entrance.
