🎒 Tips for going with kids

• Even in October, the midday sun outdoors is strong. Bring hats and sunscreen.
• Evening events (the Light Island festival, Jamsugyo Bridge) get chilly after sunset. Pack an extra light layer.
• Some free events still need on-site registration or advance booking. Check the official page first.
• A picnic mat, snacks and water help keep kids from wearing out.
