Bijarim Forest is the world's largest natural nutmeg-tree (Torreya nucifera) forest, in Gujwa-eup on Jeju's north-east coast. Around 2,800 nutmeg trees aged between 500 and 800 years grow across the forest, with the Millennium Nutmeg Tree — a roughly 800-year-old giant over 14 metres tall — its centrepiece. Fragrant red volcanic gravel paths loop the forest in 40-minute or 80-minute circuits along an approximately 3.3-kilometre trail, level and accessible. Cool, fragrant air filters through ancient canopies even in midsummer. A meditative Jeju Island stop for Muslim travellers wanting forest bathing — best paired with east-coast halal-safe options like Five Seventh near Woljeongri Beach, a fifteen-minute drive away. Modest entry fee, open year-round.
