Siltcoos Sand Camping sites are located directly on the sand, dispersed along the coast and the Siltcoos River. Siltcoos' year-round campsites must be accessed by 4X4 vehicles only. Driftwood II OHV Trail is the access point for the sand camping sites 15 to 26. Sites 27 to 30 can be accessed by Incinerator OHV Trail. Standard sites accommodate up to 20 people and five vehicles. Two group sites accommodate up to 40 people and 10 vehicles. The campground is primitive and provides no water, restrooms or campfire rings. Visitors must bring their own water, portable toilets and fire pans. This is a popular facility and reservations are recommended.

Off-road vehicle riding is the ultimate attraction at Siltcoos. Stagecoach Trailhead provides access to several trails, including the accessible Lagoon Trail and the longer Waxmyrtle Trail, which meanders through the coastal shore pine forests and along the Siltcoos River to the beach. 

Visitors also enjoy swimming and birding at the beach. A variety of shorebirds are often spotted on the shore. Seasonal whale-watching is a popular activity.
