Parking is FREE up along the hiking trail parking spots and up at Pittock Mansion itself. There is a two stall unisex bathroom next to the gift shop and ticket booth-stocked with soap and toilet paper! Yay!
Pittock Mansion is a must-see place if you are visiting Portland and a right of passage for any local resident. It was built in 1914 by Georgiana and Henry Pittock. They have some cool events that go on throughout the year that I just learned about. I think as one gets older, we appreciate these things more.
