You definitely need a 4wd or an AWD to access the bach. Note the bach itself is not fully secluded there is a thoroughfare for 4wd and motorbikes at the front. This is for people coming in from red rocks so expect to see people whilst you're there. The bach itself is really beautiful and is perfect for a getaway from the city. Just getting there makes you feel like you are miles and miles away from the city which is amazing. We also went when there were seals on the coast as well so was really cool seeing them hanging out amongst the rocks. I would definitely recommend staying here and snap at the chance if you can. You won't regret it.
