Ci sono due percorsi, uno a piedi e l’altro in macchina. Sinceramente ti consiglio quello in macchina sia per un discorso di tempo sia perché è più vasto e vedi più cose. Poi ci sono molte aree di sosta dove può fermarti passeggiare, ammirare i paesaggi e fare foto.

Yes the car park is large - when we were there I did notice caravans there

I did not come across any bbq facilities. Most likely the Cervantes area should have some. But the location is abit out of your range.

The weather from late November thru March is not kind- too hot. It is a few hours drive from Perth to the Pinnacles, be sure to drink water and take water. Australia is a huge place so be sure to check distances especially in remote area's as some travelers die due to dehydration.

Hi, about a 10 min drive on sealed road.

We had hire car & it was fine, you only drive around slowly.

I can say almost 80% of the cars that went there are from car rental

I am sorry, I really don't know about Public Holidays. As suggested by others, phone them to find out. Definitely don't miss out on seeing them.

i reckon you can. You can explore by foot and so don’t miss out. Worst case you can park in a large car park, either unhitch if there is any concern and you want to srive the loop, or get out and explore by foot. We both drove and walked when we visited and I would recommend the same to any visitor. Enjoy it!
