Blackberry Campground is perched on a heavily wooded bluff among tall cedars and Douglas fir overlooking the Alsea River. Some of the 32 sites overlook the river and others are situated beside a large, manicured grassy field. Parking spurs are paved and each site is equipped with a campfire ring and picnic table. No dump station or electric hookups are available. The nearest dump station is in Waldport.

The Alsea River is a favorite spot for drift boating, and a boat ramp is located on-site. Anglers cast by boat or from shore for Coho and Chinook salmon and Steelhead trout. Crawfishing is also a popular activity. Swimming in the Alsea River is a popular summer activity.

The area is known for elk hunting, and the campground makes a great base camp for hunting parties.
