A score is added once our review panel has played the course. Everything below is drawn from the club's own published information. See our ranking methodology.

Brian Costello, CEO of JMP Golf Design Group and an ASGCA member, designed Blackstone Golf & Resort Jeju. The course is characterised by a resort and mountain style, reflecting its setting on Jeju-do, an island province of South Korea known for its natural landscapes and as a popular destination.
Golfers planning a visit can secure tee times up to eight weeks before their intended date of play, allowing for advance arrangements for those travelling to the island.
What the club does not publish
Green fees, caddie policy and rental prices are not stated in the club's own published material, so this profile leaves those lines of the fact file empty rather than repeat figures from a booking agent that the course has not confirmed.
That matters when you plan: budget for this round by asking the club directly, and treat any rate quoted elsewhere as unconfirmed until they do. We will add the figures here, dated, as soon as the course publishes them. We will check these figures again before the next dry season and date them here when we do.

No score yet: Blackstone Golf & Resort Jeju has not been played by our review panel, so there is nothing to break down. The weightings above are the ones every scored course is measured against, published in full on our ranking methodology. Scores are never negotiated; courses may correct facts before publication, not verdicts.
Photographs from the review round are published with the review. We do not illustrate a course profile with stock images of somewhere else.
