Destination or attraction that is off-limits for tourists.

One example of a destination that is off-limits for tourists is North Korea. The secretive and authoritarian regime in North Korea tightly controls access to the country, and only allows limited and highly regulated tours for foreign visitors. The government restricts where tourists can go, what they can see, and who they can interact with, making it difficult for outsiders to truly experience and understand the country. Additionally, North Korea has strict rules and regulations for tourists, and any violations can result in severe consequences, including imprisonment.
