Not much to do at the Olary Creek Rest Area maybe go for a walk along the Dry Creek Bed to stretch the legs.
The Olary Rest Area has a pub directly across the road, so save yourself cooking a meal tonight. There is a public toilet and some rubbish bins here also.
The Old Perlubie School Rest Area has some suitable level spots to pop the caravan on and is set back from the Eyre Highway with low scrub surrounding this place.
The Orroroo Rest Area runs is another large area to pull over that will take all vans and campervans easily.
