Although quite distinct, the Pacific Northwest cities of Portland and Seattle make a great vacation pair. These siblings divided by state lines are equally as beautiful and interesting, but in different ways.
Travelers can take various pathways between Portland and Seattle. For the most scenic (and slow) route, drivers can veer to the coastline and hop the cities there. But even the most straight-shot route, up Interstate 5, is full of fun stops (although the traffic can be pretty rough in town).
A drive straight through will only take about three hours, but you can drag it out over a few days and see scenic parks and mountains, museums and gardens, islands and lakes.
Here are 10 of the many great places to visit on a road trip from Portland to Seattle.

Start in Portland’s Lan Su Chinese Garden, created as a partnership between Portland and its sister city, Suzhou, China. The botanical garden is like a growing work harmonizing design, nature and architecture. The "Garden of Awakening Orchids" is considered the most authentic Chinese garden outside of the country itself.

Famous explorers Lewis and Clark originally named this "Green Bryor Isd" in 1805, making it an interesting destination for both nature-lovers and history buffs. The island is on the Columbia River near Ridgefield, and is part of the 5,217-acre Ridgefield National Wildlife Refuge.
The massive Columbia River, also called the Great River of the West, is considered by some to be the most significant environmental force in the Pacific Northwest, according to the Center for Columbia River History.

There are so many worthy places to visit in Seattle, but one that strikes the curiosity of many travelers is Harbor Island. This unusual man-made island was originally built in 1909 as the biggest artificial island in the world. Today, it is still the biggest in the U.S. and a popular home for industrial businesses.
It may not be the most scenic place in Seattle, but its history is fascinating.
