In my opinion 3 days is okay but thats because i didn't want to and did not go to the museums.
i mostly visited the natural sightings (sunrise peak, seopjikoji, lava estuary, jongbang waterful, folk village, islet bridge etc) and managed to do so at a relaxed pace.
but if u're planning to actually go to museums or love land, etc then u probably should add a few more days.

Hello, I am currently planning for my coming trip to South Korea in October, and am wondering if I could get some tips for transportation in Jeju Island. I read online that it is nearly impossible to visit Jeju without a tour. As I will be backpacking, I am definitely going to rely on the public buses there. From your experiences in Jeju, may I know if it is possible to cover Jeju on public buses?

Also, I was looking for the best restaurants to have the famous local food in Jeju - black pork and abalone porridge - but couldn't get much recommendations online. As I will be staying in the Kkodak Kkodak Guesthouse in Seogwipo, the nearest restaurant as recommended online is about 2 hours away.

Thank you in advance for your kind assistance    Looking forward to the trip!

Thanks for the valuable information!    There'll be 4 of us on the 3D2N trip to Jeju. As it is a bit troublesome to convert the Malaysian driving license to an international one to be able to drive in Jeju (have to take 2 days of leave just to go to JPJ to convert and then get back the original license), I am wondering if I can solely depend on the public transportation there. I also plan to climb Mt. Halla as well as visit some of the places in Jeju, so I don't think a day tour is convenient for my case. I'll be spending most of my time in Seogwipo as I have booked my accommodation there (because it's near to all the main attractions). May I know if the black pork restaurant you mentioned is available in Seogwipo? I personally feel it's very hard to plan for a Jeju trip due to the distance and the public transportation woes.
Thank you for sharing the information    As I'll only be in Busan for 3D2N, I'll only be visiting a few places in Busan (Jagalchi Market, BIFF Square, Gamcheon Cultural Village, Taejongdae Resort Park, Haedong Yonggungsa Temple) before flying to Jeju. I think a rechargeable card is more convenient for this case, but am not sure if there is a place for me to reload my T-Money card at the Gimhae airport.

Oh ya....Just surfing around and saw someone renting apartment near Seoul Station for around RM500 per night. Do you guys think its too expensive for 6 of us? Or I shall just proceed to searching guesthouse instead?

Thanks in advance.

BTW I just booked ticket from Gimpo - Jeju (Eastarjet) and Jeju - Busan (jeju air) for around RM320 per person. Jeju Air is seriously a pain to book tickets >.<

tq for the reply. guess rm5000 not enough for 8 days.

  i see..thank for your info.

you should just stick to one guesthouse only, as all the attractions are easily reachable by public transport especially the mtr.  You can consider moving to different guesthouse if you go out of seoul or the 1 way journey already takes more than 3 hours.
