Note: Tours of this attraction are tentatively planned to reopen in June.
What is it? This network of underground catacombs was supposedly used for nefarious purposes in the late 19th and early 20th centuries, and is now one of Portland's must-visit, and most unique tours.
Why go? Because it's one of Portland's not-so-well-kept secrets with an intriguing backstory. Cue dimmed lights and a torch beneath the chin: legend says that a dark secret lurks beneath Portland’s streets, where many an unsuspecting (or inebriated) Portlander would wake up to find himself aboard a merchant ship bound for the Orient—a process known as “Shanghaiing.” Step inside the Shanghai Tunnels and you'll come face to face with this subterranean world, from hidden trapdoors to holding cells – just be sure to look over your shoulder.
