Hello.
I'm planning a to Western Australia, specially from Perth to Ningaloo./ Exmuoth along the Coral Coast/ Indian Ocean Hiway.
I'm hoping to avoid renting 4WD (all wheel drive), except one of the spots I want to visit is the Stock Yard Gully National park caves which is listed as accessible only with 4WD. Though I'm renting my vehicle from Perth, I'm wondering if there is a place closer to the Stockyard Gullys that a) rents 4WD for this particular one-day excursion, b) if there are buses or tour companies that will take me to the park or c) a place I can park my car and walk to the park so that I can avoid paying extra $$ for 4WD for the entirely of my trip when I only need it for one.
Any advice is welcome

I'd suggest contacting the park on their website and ask their advice. Here's the address - https://parks.dpaw.wa.gov.au/park/stockyard-gully
Alternatively contact the tourist information office or the council in Jurien Bay. If all else fails, you could always contact the WA tourist information office in Perth.

I'm not sure where you're from but it's worth mentioning Australia is currently closed to international tourists due to the pandemic. Also there have been numerous state border closures to contend with but if you live here you will be well aware of them

The Park is only about an hours walk from the nearest non-4WD required road - just park nearby where the 4WD road commences.

thanks. will look into it.
