Worth it at 18–35? Our honest read
Worth it if you're after a genuinely unusual experience rather than a quick photo stop—that 4.8 rating from over 12,000 reviews suggests it delivers on the weird appeal of driving through a 1.2km tunnel carved into a mountain. You'll need to budget for paid entry and likely book a tour (42 options available), so factor that into your costs, but the consistently high ratings indicate people feel they got something memorable rather than just ticking a box.
