Climbing Hallasan (Halla Mountain), Jeju Island’s highest peak, requires advance reservations for foreigners on popular summit trails like Seongpanak and Gwaneumsa to protect the environment and manage crowds in Hallasan National Park. Reservations are free, open from the first business day of the prior month at 9 AM, and limited (e.g., 1,000 spots for Seongpanak).
