The trolley ran late almost the entire day and they only came every hour. It was very hard to see much when you had to wait so long in-between trolleys. Other than that, the driver was knowledge, friendly, and helpful.
This was our first time to Portland and with only a few days the was the BEST money spent! We to the Gorge bus tour one day caught the trolley the same afternoon. This helped us plan our next day stops from the trolley! Would definitely use this option on a return visit.
Columbia River Gorge tour was excellent! The Trolley was good, but really didn't allow enough time to see everything. It should definitely run later than 4:00 during the summer. I would recommend riding the Trolley from start to finish without getting off. You need to spend several hours at some stops in order to see everything.
