Went there in september, $25 for our family, which is outrageous. Was like being in a 3rd world country, no receipt, no facilities, dirty old overflowing rubbish bins on the walk etc. The chasm is good, but would never go there again. Am not angry about it, it's their land and they can charge what they want, but would never go again.
Actually thought The Western Macdonald Ranges were all pretty much crap. Fully intended to stay at glen helen "resort" and didn't even get out of the car it was that bad. I'm sure some people on here love it but the brochures sure don't match the reality! Went on to Palm Valley instead and it was the highlight of our 2 month trip. Absolutely beautiful.
