The design
The architecture
Mammoth Dunes thrusts you into an inland sea of golden sand, where vast fairways sweep over natural ridges and the ground-game rules. David McLay Kidd’s philosophy is in full flight: bold, broad, and brilliantly playable, the course entices you to hit heroic shots yet cleverly rewards smart angles and creative approaches. Greens are colossal and full of movement, always inviting the unexpected, while natural sandy waste areas keep your adrenaline up from the tee box to the final putt.
Kidd’s aim was a golf course that’s boldly fun, accessible, and inviting regardless of skill—where the landscape and design make every round memorable.
Defining features
- Enormous fairways offer strategic choices on every tee
- Dramatic, exposed sand ridges provide unforgettable scales and vistas
- Collossal, undulating greens reward imagination—and punish carelessness
- Sandy waste areas present recovery opportunities and adventure
- Short par-4s and daring par-3s fuel scoring swings and risk
- Routing evokes classic inland links, but on massive sandy terrain

Hole 6
Horseshoe Gamble
PAR

YARDAGE
332 yds
A thrilling drivable par 4 with a bunkered, horseshoe-shaped green and expanses of sand short and right. It’s famously risk-reward—aim for the green or lay back for position.
Play it smart
Aggressive tee shots can set up eagle or birdie but risk tricky recoveries from sand or awkward angles; finding the right spot for your second matters as much as reaching the green.
Where it bites
Miss right into sand for an unpredictable up-and-down, or overplay the green and face brutal putts from the wrong horseshoe segment.
Course management
Shots to think about
Approaching a drivable par 4 like the 6th
Balance risk and reward—if you go for the green, do so with a confident, precise drive; laying back for a full wedge can be smarter, avoiding tough recoveries.
Facing a short par 3 over sand (hole 13)
Club down for the wind, trust your number, and hit the center of the green to avoid the deep hazards short and right.
Playing from a vast fairway with bunkers lurking
Pick your angle based on the pin; fairway width is generous, but optimal approaches depend on savvy tee placement.
Recovery from a sandy waste area
Assess your stance and carry—sometimes a safer pitch is better than gambling for the green from a tough lie.
Reading massive sloped greens
Get a good feel for slopes on your approach—putting across big contours can easily lead to three putts if you’re careless.
Second shots on risk-reward par 5s
Lay up to your favorite number unless you have a clean line and the wind’s at your back; bold plays can unlock eagle, but the penalty for error is high.
On the day
What to expect
Conditions
Consistently firm and fast, with manicured fairways and true, sprawling greens embracing the sandy environment.
Pace
Generally brisk for a modern resort course, though long walks and dramatic terrain mean rounds are substantial and unrushed.
Vibe
Relaxed, high-energy, and unpretentious—golfers come for fun, adventure, and the resort camaraderie.
Dress code
Standard resort golf attire—collared shirts and golf shorts/pants; no strict traditional dress code.
Before you tee off
Your game plan
01
Warm Up Your Driver
Huge fairways let you swing freely off the tee, but accuracy on placement still rewards you—practice bold but smart drives.
02
Sharpen Your Short Game
Around-the-green creativity is key, with bump-and-run, chips, and imaginative pitches required on the giant putting surfaces.
03
Plan For All-Weather
Open terrain means wind can be a factor—layer clothing and prep for exposed, sunny walking.
