The course & your visit
Grass greens in the Roxby Downs desert
Roxby Downs Golf Club is an eighteen-hole course in the town of Roxby Downs. Its course account describes couch greens and grassed tee blocks. Beyond the fairways is desert rough: a distinct change in the sort of lie a player may face.

Where the fairway meets the desert
The club says its local preferred-lies rule on fairways still permits the use of a grass mat. Read that local rule before playing so you know when a mat may be used. The club also says there are no sand bunkers, although the dunes beyond the fairway can present a similar sort of lie.

A self-service visitor round
The club says the course is open during daylight hours on all seven days, while the clubhouse is unstaffed. It directs visitors to the payment box at the clubhouse behind the first tee. Club hire is listed as available from the garden shed. Those arrangements make the first tee and clubhouse the place to orient yourself before setting off.
The club publishes a seasonal competition programme. Check its current calendar before planning a competition round; a social round follows the separate self-service arrangement.
