St Cloud Ranch is a small park along the Columbia River that provides a short, less than half mile, loop walk, and an area for picnics. The is a national forest service site, so a forest service day use fee is required.
In addition to the loop orchard trail, a trail has been cut through the brush to the east. I followed the trail about 500ft to where it hits Archer Creek. I could see that the trail continued on the other side of the creek, but I was not prepared to ford the creek to follow it. During late summer and early fall you could explore a longer hike up the Columbia River to the boundary of the Franz Lake Wildlife Refuge.
