A straightforward par 4 opening hole that plays relatively flat with a fairway that narrows as it approaches the green. Bunkers guard the right side of the green, requiring accuracy on the approach shot to avoid sand.

A short par 4 that demands precision over distance, with a tight landing area off the tee. Water hazards and bunkers frame the green, making this a deceptive test despite its modest yardage.

The first par 5 of the course, this three-shot hole features a wide fairway that provides multiple angles of attack. Hazards tighten around the green, rewarding aggressive play but punishing misalignment on the approach.

A gentle par 4 with a relatively straightforward layout and forgiving fairway corridor. The green opens to receive a well-struck approach, though bunkers protect the sides and back.

A longer par 4 that plays uphill, making distance management critical. Out-of-bounds or heavy rough lurks on one or both sides of the fairway, demanding a committed tee shot.

The course's #1 handicap hole, this par 5 is a true three-shot test with strategic bunkering and potential water hazards in play. The fairway requires careful positioning to set up a manageable third shot into a well-guarded green.

A short par 3 that plays downhill with a modest target. Despite its length, hazards around the green—likely bunkers and rough—make it a precision test rather than a birdie opportunity.

A short par 4 with a dramatic elevation change or doglegging shape that compresses the hole despite modest yardage. Greenside bunkers or water create a demanding finale to the front nine.

A mid-range par 3 that sits as the front nine's closing hole, providing a solid finishing test. Bunkers and rough frame the green, requiring an accurate mid-iron for par.

The back nine opens with a moderate par 4 that features a relatively open fairway but demands position play. The green is protected by bunkers and possibly water, making the approach the key challenge.

The second-hardest hole on the course, this par 5 is a powerful three-shot hole with strategic hazards throughout. Bunkers and water likely influence both fairway positioning and the third shot into a narrow green complex.

A solid par 4 with balanced length and difficulty, featuring a fairway that may narrow or doglegging slightly. Greenside bunkers and rough demand accuracy on the approach to a well-protected green.

A short par 4 that compensates for its modest yardage with tight fairway corridors and strategic bunkering. The compact green complex leaves little room for error on the approach shot.

The course's shortest hole, this par 3 plays as a birdie opportunity but features enough green-side bunkering and rough to punish poor aim. The small green target demands precise distance control.

A short par 4 that offers a rare birdie chance with a narrow, reachable fairway and open approach to the green. Hazards narrow the fairway or guard the green, rewarding an aggressive yet accurate tee shot.

A compact par 4 with a straightforward layout that plays shorter than par, inviting aggressive play. Bunkers and out-of-bounds or rough frame the hole, making accuracy more important than distance.

A well-balanced mid-length par 4 in the closing stretch with a fairway that may bend slightly or sit on uneven terrain. Strategic bunkering around the green requires a precise second shot to finalize the scoring opportunity.

The finishing par 4 provides a solid final test with a fairway that may narrow near the green or bend strategically. Bunkers and rough protect the green, making the closing hole a fitting capstone to the round.
