Halla Ecological Forest is an ecological park in Jeju with several forest trails and ponds. It has a palm mat path, a cypress path, and a barrier-free trail that wheelchairs can use. Walks with a forest guide at 10 a.m. and 2 p.m. require advance booking on the website, and there is no admission or parking fee. The altitude makes it colder than Seogwipo or Jeju, so warm clothing is needed.
