Long park is looooooong!
This waterfront stretch of green space, concrete and river views is host to a number of different events and festivals throughout the year, most notably the Rose Festival Fleet Week, Cinco De Mayo, Portland Blues Festival, The Bite of Oregon, the Saturday Market, and probably a whole lot more than I can count or remember.
Sporting gorgeous cherry blossom trees (particularly beautiful in mid-April), a view of the Willamette (filled to the brim with brown trout!), an awesome fountain perfect for cooling off on a scorching hot summer day (or showering outdoors, as many of the homeless do), and scores semi-aggressive geese (that fill the park with squishy "land mines" so...watch your step!), it alternates between a wonderful place to picnic on a sunny weekend afternoon, and a soggy slog of swampy strata filled with vermin and crazies. More often than not, it's the former, but...I recommend visiting during the day, or early evening. After dark, the Walking Dead emerge.
Regardless of when you visit, you'll constantly be dodging joggers, runners, bikers, strollers, wayward animals, and the occasional person undergoing a mental health crisis, screaming at the crows and pigeons. Stay alert and keep those calves and hammies warmed up!
I know it sounds like I'm shitting on Tom McCall Waterfront Park, but really, I'm not; the geese do enough of that for the both of us. On the whole, it's a fantastic public space that unfortunately comes with a warning labels to ensure the safety of its users. Keep those in mind, come prepared, and you're sure to be fine. Just keep your valuables close at hand.
