Hi there Katy! Good to hear from you. I have 2 horses in Geoje. There is a riding school there, about a 20-25 minute drive from both Okpo and Gohyeon depending on traffic. If you send me your email address I'll write in detail about what facilities etcetera are there, plus the fees. My email address is firstname.lastname@example.org
It would be great to have company!
Looking forward to hearing from you,
