The House on the Rock is one of the most genuinely strange tourist attractions in the United States. What started as Alex Jordan Jr.'s personal hideaway on a sandstone chimney above the Wyoming Valley grew over decades into a sprawling complex of rooms and warehouse-sized halls stuffed with collections: a 200-foot model sea creature, the world's largest indoor carousel (269 lit animals, none of them horses), self-playing orchestras of mechanical instruments, doll-house dioramas, ship models, antique guns, and dozens more.
The full visit takes three to four hours and is laid out as a one-way walk through a sequence of themed spaces. Don't try to understand it; just go with it. Open daily from late March through early November; reduced hours in the off-season. Far weirder and more memorable than the brochure makes it sound.
