For Baengnokdam summit hiking on Hallasan, verify the trail reservation rules before departure. Jeju's official tourism information identifies Seongpanak and Gwaneumsa as the summit routes, with reservations applying to the upper Jindallaebat–Baengnokdam and Samgakbong–Baengnokdam sections respectively. Eorimok, Yeongsil, Donnaeko, Eoseungsaengak and Seokguram are separate walking or climbing routes that do not lead to the summit and are not covered by those summit reservations. Temporary construction restricted the upper Gwaneumsa route in August–September 2026, illustrating why older information can be misleading. Use the official Hallasan Trail Reservation System for the intended date and latest notices about Seongpanak/Gwaneumsa operation. Weather and safety controls may alter summit access; check ID, confirmation and turnaround-time requirements.
