Road access to towns in South Australia's far north has been cut by recent heavy rain, leaving many tourists - among them several groups of musicians - stranded

The Oodnadatta and Birdsville tracks, and part of the Strzelecki Track have been closed, leaving many communities in the area inaccessible by road.

Rain began falling heavily on Friday, closing all roads to William Creek, and over the weekend the roads into Arkaroola and Marree were also closed.

Phil Turner from the Marree Hotel said although the rain had stopped, roads still needed to dry out.

He said those stranded included groups of musicians who had been finding ways to keep themselves, and everyone else, entertained.

"We've got three campers here, three separate lots, and they're all musicians," he said.

"They've teamed up each night and pulled out everything from cellos and violins, to guitars and drums, and we've had a couple of jam sessions, so that's been lovely in the evening.

"During the day there's plenty of walks around town they're doing."

Mr Turner said many stranded tourists had also been taking flights to see water in Lake Eyre, continuing what had been a strong tourism season.

"The Australian dollar has had an effect on that; there's a general stability in government without elections, both state and federal that we've had in the last two years," he said.

"But I think there's just a sort of levelling off of confidence which has seen more people holidaying and taking advantage in everything the far north of South Australia has to offer."

On Friday, local resident Talia Sheppard said international visitors were not upset about the rain.

"It's beautiful for the countryside for them to see water lying around; it's when the outback sort of flourishes," she said.

"They're pretty lucky to see it like that, and most of the international tourists see it that way as well."
