Traveling to Black Diamond by RV

This scenic route follows the Green River through farmland and forests, making the drive part of the experience. From Seattle, take I-405 south to SR-169 south for a straightforward 45-minute drive that avoids most mountain passes.

RVers approaching from the east should use I-90 to I-405 rather than attempting the winding mountain highways directly. SR-169 handles large RVs without issues, though the road does include some rolling hills and curves typical of rural Washington. The route passes through Maple Valley and offers several fuel stops before reaching Black Diamond.

Stock up on supplies in Enumclaw, about 10 miles southeast, which has a Safeway, hardware stores, and RV-friendly gas stations with extended pump lanes. Black Diamond itself has limited services, so plan accordingly. The nearest major RV supply store is in Auburn, about 20 miles north via SR-164.

For those continuing to Mount Rainier, SR-410 from Enumclaw provides the most RV-friendly access to the national park's northeast entrance. This route stays open year-round to the Crystal Mountain area, though the full crossing to Yakima closes seasonally. Always check current road conditions, especially during winter months when chains may be required.
