These fascinating tunnels were originally built during World War II in order to protect oil supplies from the Japanese bombings, though they were never used for that purpose.

Soak up the sun and enjoy the "moonscape" appearance of Carlo Sandblow. During the day, it's the ideal place to relax and spend some time with the whole family.

Around 250 trees, such as a tulip tree, pines and giant sequoia trees, are found in the lovely Gardens of Europe, where you can enjoy a walk by the lake in a sunny afternoon.

Dubbed the "home of American coffee culture," Portland knows what it takes to brew the perfect cup. In a 2016 survey of 100 U.S. cities, Portland topped the list, boasting the most coffee roasters per capita and the highest number of cafés. With so many spots to enjoy a great cup of coffee, you might think there's little room for discovery — but that couldn’t be further from the truth. Portland’s coffee scene continues to evolve, with unique additions like Oracle Coffee Company, run by Andy Hurley, the drummer of Fall Out Boy and a self-described "vegan straight-edge anarchist." The choices are endless, but for a glimpse of where it all began, visit the original Stumptown Coffee Roasters location at 4525 Southeast Division Street. Many credit this tiny space with launching Portland’s rise to coffee fame, now a chain with outlets from New York to LA.
