The guesthouse transferred to a new location and a lot of tourists get lost trying to find it.....a lot means around 80% of the total guests. I think it has something to do with the old release of the Lonely Planet Guidebook they are using.
Unique Suggestions: Upon arrival to Gyeongju, visit the Korea Info Center (there is one at the entrance of Gyeongju Bus Station) and confirm the address from them.
Fun Alternatives: No alternative...you definitely have to check this out. The place is wonderful...it is only the address that is causing the problem.
This Seokgulam inside, only look to great ancient grotto Buddha statue, and no Photo Inside statues. Seokgulam was the UNESCO world heritage site of Gyeongju.
