A park with a pleasant lake, picnic shelters and restrooms maintained by Portland General Electric. 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.
There is also a scenic yet challenging par 55 disc golf course which is one of the only courses in the Pacific NW to feature extensive water hazards with 11 holes playing over or adjacent to water.
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.
