1. International Rose Test Garden
Portland calls itself the City of Roses, and this is where that nickname earns its keep. The International Rose Test Garden holds over 10,000 rose bushes across approximately 650 varieties, spread across terraced beds with downtown Portland and Mount Hood as the backdrop. It is the oldest continuously operating public rose test garden in the United States, and new cultivars arrive from around the world each year to be evaluated for disease resistance, bloom form, color, and fragrance. About 700,000 people visit annually. The garden is free and open daily from 5 AM to 10 PM, which means early morning visits are entirely possible and highly recommended. Peak bloom hits in June, though roses flower from April through October. The garden sits inside Washington Park, just a short walk downhill from the Portland Japanese Garden. You can easily visit both in one trip, and if you are already at the Oregon Zoo or Hoyt Arboretum, they are all within the same park complex. Of all the things to do in Portland, this is the one that surprises people most. The scale is bigger than you expect, the scent on a warm June afternoon is overwhelming, and the view is genuinely one of the best in the city. This is a top sight in Portland that costs nothing.
