Hyeopjae Cave lies within Hallim Park at 300 Hallim-ro, Hallim-eup, Jeju City. The Korea Tourism Organization’s accessible-tourism page describes free wheelchair loans within the park but explicitly excludes the cave from wheelchair-accessible areas. Accessibility elsewhere in the park therefore should not be read as confirmation that visitors can enter the cave in a wheelchair.
The listing also mentions stroller rental, subject to conditions on the pickup location, age and fee. Review the cave’s steps and floor conditions before deciding whether the entire family can follow the same route.
The tourism page contains internally inconsistent numbers for November–February opening hours, so this guide does not repeat them as confirmed times. Check Hallim Park’s latest official schedule and admission cutoff before travelling.
