Playing Tips

Wide fairways invite aggressive tee shots, but stray drives can be penalized by the surrounding forest so prioritize accuracy when needed.

At roughly 1000 meters elevation the ball will carry farther than at sea level, so consider clubbing down on longer shots.

Be aware that the course uses both Zoysia and Bentgrass greens, so expect noticeable differences in pace and how chips hold between green types.

Exposed holes can be affected by mountain breezes, so always check wind direction and strength before committing to long carries.
