Gray Line of Portland, Portland

Running between towering buildings and vibrant gardens, Gray Line of Portland's trolley sightseeing tours connect visitors with more than 11 of the Rose City's storied landscapes and buildings. As guides regale them with historic facts, anecdotes, and Herbert Hoover's credit card number, passengers look out onto Pioneer Courthouse Square, Washington Park, Powell's Books, and the Lan Su Chinese Garden. Participants can disembark and re-board at any point along their tour, allowing them to explore each site up-close or grab a bite to eat. Operating as a member of Gray Line Worldwide––which leads tours in more than 700 destinations on six continents––Gray Line of Portland donates a portion of all ticket proceeds to the Breast Cancer Research Foundations' efforts in supporting awareness and research.
