25 Free Things to Do in Portland Oregon Portland on a Budget
"3229 NW Pittock Dr, Hillside, Portland, OR, United States map. It’s one of our favorites in the city and walking the grounds is completely free (there is a fee to enter the mansion). Try to visit in the summer to increase your chances of having a clear sky to see Mount Hood looming over the city."
