Before you go

Everything to know on arrival

Know before you go

  • Plan to walk: every course at Sand Valley is walking only.
  • Book a caddie ahead through caddie services; single-bag requests can't be guaranteed.
  • Rent a push or pull cart or bring your own; motorized pull carts struggle in the sand.
  • Use the putting green by the first tee and the Sand Valley range (closes at 5 p.m. Thursdays).
  • Morning rounds before 8 a.m. are speed slots meant to finish in under 4 hours.
  • Pick tees by rating: the card lists ten tee sets from Black (7,063) to Royal Blue (4,064).
  • Golf-only cancellations need 30 days' notice to keep your deposit.
  • Reserve rental clubs with the golf shop in advance.

Arrival & check-in

Sand Valley is at 597 Leopold Way in Nekoosa, about 25 minutes from Wisconsin Rapids and roughly 1 hour 40 minutes from Madison. A shuttle runs between the clubhouse, golf shop, lodging and the first tees, and you can request one online. If you booked a caddie, plan to be at the first tee 15 to 20 minutes before your tee time.

Carts & walking

All courses at Sand Valley are walking only. Caddies are strongly encouraged; most carry two bags, so single-bag and junior caddie requests can't be guaranteed, and fore caddies are offered for groups of 2 to 4. Push or pull carts can be rented, or bring your own, though motorized pull carts struggle in the sand. Riding carts are available only for guests with a medical need, arranged in advance (cartrequest@sandvalley.com).

Practice facilities

The Sand Valley Golf Range is open from sunrise until an hour before dusk and closes at 5 p.m. on Thursdays. Warm-up areas are first come, first served. Putting greens sit next to the first tees at Sand Valley and Mammoth Dunes, and shuttles run to the other courses. The resort also offers instruction.

Rentals & pro shop

Rental clubs (with two sleeves of balls) are available by the day; reserve them with the golf shop at 888-651-5539 or golfshop@sandvalley.com. Hickory sets are also available.

Food & drink

Food and drink on property includes Craig's Porch overlooking the Sand Valley course, Aldo's Farm & Table, The Gallery, Mammoth Bar and Bill's BBQ beside the Sandbox. Lodging guests should book dinner ahead.

Pace of play

Rounds starting before 8 a.m. are speed slots expected to finish in under 4 hours. Later rounds should take 4 hours 15 minutes or less.

Policies

Mammoth Dunes is open to the public through the resort's tee-time booking, and stay-and-play guests are welcome. Golf-only bookings must be changed or cancelled at least 30 days before arrival or the deposit is forfeited. Golf and lodging packages have seasonal notice windows (in 2026, 7 days in late April and mid-October, 45 days from May 1 to October 4). If weather keeps you from playing, tell the golf shop while on property to get a voucher for future golf; once you tee off you are not eligible. The courses close for the winter.
