If you're planning a visit to Neuschwanstein Castle, you've likely landed on neuschwanstein.de. This is the official website of the castle, run directly by the Bavarian Palace Administration — a government body that manages historic properties across the state. That alone gives it a level of legitimacy most tourism sites can't match.
The site has been on the web since the mid-1990s, with an unbroken history visible in the Wayback Machine. Its security is solid, it publishes a legally required Impressum, and it links to social media accounts you can cross-check. There's nothing here that suggests a scam or fake site.
One thing to note: while neuschwanstein.de provides information and a direct link to buy tickets, the actual ticket sales happen on a partner site (hohenschwangau.de) which charges a booking fee. That's standard for this castle, not a red flag. If you're checking for reviews or scam concerns, neuschwanstein.de itself is trustworthy — the only risk is making sure you end up on that official ticket page rather than a reseller.
In short, neuschwanstein.de is the real deal. Use it for planning your trip, but follow the official ticket link carefully.
