13. Elk Rock Island
In his guide to Portland, Chuck Palahniuk recommended this place... and still nobody goes here. For great swimming and a taste of what it would be like to own a private island, head here during the summer. Be prepared to wade across 20ft of shallow water as part of the journey (though, with this year's water levels, you may be in luck).
12. The South Park Blocks
You never know what you'll see in the Park Blocks. Really. It could be the Unipiper, a horde of bar-hopping superheroes, or just some geezer talking to squirrels. And while it’s maybe a cheat to put the entire stretch down as one park, well, deal with it. Because it basically is one long park.
