Newport to Mosier Road Trip: Oregon Coast to Columbia Gorge

The drive from Newport, Oregon to Mosier, Oregon stretches approximately 225 miles (362 km) and takes about 4 hours of pure driving time, but plan for 5-6 hours with stops. This route traverses Oregon’s diverse landscapes: from the foggy Pacific coast at Yaquina Bay, across the lush Coast Range, through the Willamette Valley’s vineyards, over the Cascade foothills, and into the arid Columbia Gorge.

A peculiar detail: near Mosier, the historic Mosier Twin Tunnels were carved through basalt in the 1920s and later reopened as a hiking and biking trail along the Historic Columbia River Highway. This alignment once carried US 30 before Interstate 84 bypassed it.

Begin at Newport’s historic bayfront on US-101. Take OR-18 east toward Salem. This two-lane highway winds through the Coast Range; check for fog and logging trucks. Fuel up in Newport (last inexpensive gas before Salem).
