- I’m guessing you’ll want to get a passport for a Distillery Row tour: http://www.distilleryrowpdx.com
- Brewpubs are ubiquitous in Portland…McMenamins have converted lots of old buildings in town, Bridgeport has been around along time, Widmer has a great selection and Deschutes is just a couple blocks from your apartment. http://www.mcmenamins.com, http://www.bridgeportbrew.com, http://widmerbrothers.com, http://www.deschutesbrewery.com There are soooo many other small, craft brewers in town; best to just explore and see where you end up.
- Definitely go to the Oregon Zoo. It is awesome (especially if you have children) and is super easy to get to from Downtown. http://www.oregonzoo.org
- Hiking either in the Gorge or Forest Park is always worthwhile (especially for clearing up hangovers): http://www.portlandhikersfieldguide.org/wiki/Columbia_River_Gorge_Hikes http://www.forestparkconservancy.org/forest-park/maps/
- A half-day scenic drive thru the Columbia Gorge between Portland and Hood River along the old historic highway is pretty special: http://traveloregon.com/cities-regions/columbia-river-gorge/
- The Chinese Garden and Japanese Gardens are both worth a walk-thru: http://www.lansugarden.org http://japanesegarden.com
- The Portland Farmers Market is PACKED every Saturday morning: http://www.portlandfarmersmarket.org
