How far is Seattle from Portland and how long will the road trip take?

| Mountain Route Note: mountain route may be unavailable during winter due to road closures | 330 miles | 7 hours |
The best route for a road trip from Portland to Seattle depends on the time of year you want to travel. If you are going in winter, follow the coastal route, which will cover 270 miles and take you about 5 hours to drive.
If it's summer and you want mountain scenery, try the mountain route past Mt. Rainier, which will take about 7 hours and cover 330 miles.
Neither of these routes is the most direct one, because the shortest route is straight up Interstate 5, and isn't particularly interesting. Instead, the coastal route will take you along the rugged bays and headlands of Oregon and Washington.
The mountain route will take you past the famous Mount St. Helens and into the spectacular Mt. Rainier National Park. Both routes take place mostly on highways and smaller roads, making the driving interesting.
Both routes avoid large cities until you reach Seattle. This means traffic shouldn't be a problem anywhere along the route.
