Traveling to Sumas by RV

Sumas sits right off Highway 11, which connects directly to Interstate 5 at Exit 256 in Bellingham, about 15 miles east. The route stays flat and RV-friendly the entire way, with no bridge restrictions or weight limits to worry about. Highway 11 itself handles big rigs easily -- it's a major truck route to the border crossing.

From the south, take I-5 north to Exit 256 and follow Highway 11 east through Ferndale and Laurel. The road widens to four lanes approaching Sumas, giving you plenty of room to maneuver. Northbound travelers from Vancouver can cross at the Sumas border and immediately access town facilities.

Some RVers park overnight at the Flying J in Ferndale before making the border crossing. Winter road conditions rarely affect this low-elevation route, though morning fog can reduce visibility during fall and spring months.

Explore the Sumas Area

Hit the dump stations early in the day if possible -- border traffic picks up by mid-morning and can create congestion around town. The Shell station on Cherry Street offers propane fills, which saves a trip if you need both services. For fresh water, several RV parks allow day-use fills even if you're not dumping there.

Stock up on supplies at the IGA grocery store on 2nd Street before heading into Canada, where prices run higher.

The local dump stations typically provide rinse hoses, but bring your own gloves and be prepared to wait during peak summer travel periods when border crossings get busy.
