There were quite a few people at the mansion, but the trail up from Cornell was not too crowded. Most people take the easy way up and drive in the mansion's parking lot. I enjoyed the hike, and the view of Portland from the mansion grounds was great. If I have been there it has been so many years ago that I forgot what it's like. It's cool that you can walk around the mansion without having to pay for a tour. It's about as good a view of the city as you can hope for. Feels like you are right on top of it.
