How hot is it in Portland this summer? So hot that there's actually a line outside of Salt & Straw, presumably to trick the mind into thinking it's January, when there's also a line outside Salt & Straw. For a less psychological cool down, though, nothing beats a nice plunge. And while the mountains and coast are full of amazing lakes and beaches, they don't account for laziness. None of the swimming spots on this list are more than an hour away. Hell, some are right in town. Even better, there are no lines! And you can always bring a cooler of ice cream.
