Collins Beach, Sandy river beach on Sauvie Island, Columbia County, Oregon, USA

Collins Beach is a river beach along the Columbia River at Sauvie Island with a narrow shoreline bordered by dense trees. The woodland provides natural shaded areas throughout the length of the beach.

Nude use of Collins Beach dates to at least the 1970s. It became one of Oregon's two official clothing-optional beaches after Glass Bar Island in Eugene closed; the other is Rooster Rock State Park. The Oregon Department of Fish and Wildlife administers it with the Columbia County Sheriff's Office.

Nude use at Collins Beach has been documented since at least the 1970s, making it one of Oregon's two official clothing-optional beaches, alongside Rooster Rock State Park, after Eugene's Glass Bar Island closed. The Oregon Department of Fish and Wildlife administers it with the Columbia County Sheriff's Office.

The beach begins about 0.25 miles (400 m) past the point where Reeder Road turns to gravel, and it is open daily from 4:00 a.m. to 10:00 p.m. The Oregon Department of Fish and Wildlife administers it with the Columbia County Sheriff's Office. The nude section is not fenced off from the non-nude North Unit Beach, so check where you are walking.

A concrete sailboat sits permanently on the beach near the tree line and serves as an unexpected landmark. Many visitors discover this art object as a surprise while walking along the shore.
