Saryeoni Forest Trail (Bijarim-ro Entrance) is a hiking course on Jeju's Bijarim-ro that runs through dense stands of Japanese cedar and cypress. The trail stretches about 12 to 15 kilometers, taking under 30 minutes if you only walk the area near the entrance but over 3 hours for the full route. From the parking lot on the Bijarim side, it is a 2.4 to 2.9 kilometer walk of about 50 minutes to the entrance, and a bus stop with service in both directions sits in front of the entrance. Nothing along the trail sells water or snacks, so bring your own in advance.
