We decided to go camping in Namhae for the vacation time during the Chuseok holiday. Namhae is a quaint beach town a 2-1/2 hour bus ride from Busan.
From the Busan West Bus Terminal (부산서부시외버스터미), it costs 11,900₩ to take the bus to Namhae (남해 시외버스 터미널). I recommend camping at Sangju Beach (상주은모래비치). There isn’t much to do or eat there, but it has facilities for camping (including bathrooms and showers in the summer). I highly suggest bringing food, but there are many marts around that sell drinks and instant ramen, etc..
