The Jeju 4·3 Peace Foundation accepts guided-tour reservations from midnight 30 days before the visit until the preceding day. Exhibition-hall tours start at 09:00, 10:00, 11:00, 13:00, 14:00 and 15:00, last roughly one hour and accommodate up to 40 people each. The separate outdoor Jeju 4·3 Peace Park tour starts at 10:30, lasts about one hour and requires 2 to 40 people. Hot-weather alerts and other conditions can force outdoor tours to be canceled or moved indoors. Guests should arrive at the information desk five minutes before departure; unannounced lateness may cancel the booking. The booking page does not specify whether foreign-language guiding is available; contact the operator beforehand if needed. Check live space availability in the reservation calendar.
