Telluride’s entire downtown corridor is a designated National Historic Landmark District, which means, wherever you roam, you’re liable to think you’re in a Clint Eastwood western. For the full backstory (including details about Telluride’s former red-light district), head to the Telluride Historical Museum and pick up a map for a self-guided walking tour of downtown, or book a group tour with resident expert Ashely Boling.
