Best known for Portland's oldest public rose garden, Peninsula Park also offers a splash pad, playground, and picnic areas, making it a two-for-one outing with the garden in full summer bloom.
What's on site. OpenStreetMap maps toilets on site, drinking water, playground alongside at this location.
When to go. Peak summer highs in Portland average 80°F — warm enough for a splash pad through most of the season without being punishing at midday.
How long it's open. Roughly 13 weeks a year, from June to September. Seasons shift year to year and municipal pads often close early for maintenance, so check before a long drive.
