You actually have three otpions and all I can say for advice on which one is best is going to be based on your starting and ending point.
~The MAX Light Rail extends further out and offers options to avoid driving to far into town. It is also convenient for those that live in town.
~TheVintage Trolley is great if you are already down. As it is mostly provides public transportation in downtown Portland.
~Tri-Met bus is your third option. -- at the time of writing this lines #12, #19, or #20 will drop you off close to the market.
As you can see, Portland Saturday Market chose its sight to be accessible for all. In addition, if you spend $25.00 from an Market artisan, you can visit the information booth and receive a free bus pass for your return trip. We look forward to seeing you at the start of Market season, the first Saturday in March!
