• Guided tours book out since the grounds open only on a guided tour (inside, outside or the garden), with tickets released online about two weeks ahead
• Audio tour in the center covering the palace's history and the courts and library that work there
• Online 360-degree tour of the interior on the palace website, a good preview before you go or a stand-in if tours are full

The Visitors Centre explains the Peace Palace, the 1913 building that houses the UN's International Court of Justice and the Permanent Court of Arbitration. An audio tour covers the palace's history and the work of the courts inside.

The grounds are open only on guided tours: inside the palace, around the outside, or through the garden. It suits school-age kids curious about how countries resolve disputes without war.
