You may have seen a big pink trolley going around Portland. We hopped on it last week.
I have always found hop on/hop off tours to be a good way of getting the lay of the land, as well as for transportation to attractions.
I have used that for getting around in Toronto and Philadelphia, and we had recently taken Gray Line's waterfall tour in the Gorge.
This was the first time we had done it with somewhere so familiar.
I enjoyed the tour information. While there were things I knew, there were other things that I didn't know or had not thought of.
For example, as we were headed from downtown to Washington Park, the driver pointed out the Pittock Mansion, which you can see. It makes sense, but I had never noticed.
At the same time I had been thinking that with all of the various public transportation options, the hop-on, hop-off option would not be practical; there are much easier ways to get around.
However, there were people who got off at the Rose Garden and on the Waterfront. They did seem to be from out of town, so they wouldn't know that you could just hop on the streetcar or train or Bus 20, but that makes sense.
We just got on at the first stop at Director Park, and rode the whole thing through once.
That is a reasonable option, but not the only one.
COVID: We were sitting right by an open window and they were not particularly full, so you could argue for or against masking. Use good judgement.
Accessibility: All of the trolleys have a wheelchair lift, but they do ask for 48 hours notice.
