Jeju is really a lovely place for hiking, and enjoying the nature. I went there in early Oct for 3 days, perfect weather. A recommended place for relaxing and refreshing out from the busy living in the city. I'd love to visit Jeju again! 
  
Thanks Victor for your guide. We really had an enjoyable vacation, relaxing, and with nice Korean food! I'm really satisfied with the tour package. Reasonable price, and with nice hotel included. 
  
Cheers,
