Quick Overview

Newcastle has several RV dump stations in the area, with some offering free access to travelers at the junction of Highways 16 and 85 in northeastern Wyoming's Black Hills region. This Weston County seat of about 3,500 sits at the western edge of the Black Hills near the South Dakota border, serving as a gateway for RVers heading between the Wyoming plains and the Sturgis, Deadwood, and Mount Rushmore attractions across the state line. RV dump station and sani-dump access in Newcastle provides important tank maintenance for travelers who may be covering long distances between services -- the nearest major cities are Gillette 70 miles northwest and Rapid City about 90 miles east. The sanitary dump station facilities serve both east-west Highway 16 traffic and north-south Highway 85 travelers connecting the Black Hills to the Thunder Basin region. Newcastle's downtown has a handful of local businesses, a small museum, and the kind of genuine frontier character that comes from being a real working community rather than a tourist town. The surrounding landscape of pine-covered Black Hills ridges and high-plains grasslands creates scenic diversity that makes the drives around Newcastle surprisingly beautiful for this often-overlooked corner of Wyoming.
