The thing with these popular scenic tourist spots is that it is on everybody’s to see list. If you reach the car park at peak hours (generally 11 am to 5 pm in summer), the first thing to do is to find a parking lot! Every damn driver seems to reversing his car close to you when you are reversing yours! Then, you hike to the famed scenic spot, only to find that there are tons of other people already there and yakking here and there - loudly. The worst are Asians - PRCs, Indians and damn PeeNoises. Impossible to get a clean panoramic shot or video without some idiot sticking his head, hip or bump into your precious peekture.
However, if you arrive after 7.30 pm, the parking lot should be empty. You can sleep in the back of the SUV with the seats flat down and an inflatable mattress from Amazon. Next morning, wake up at 5 am and start your hike. You are guaranteed solitude. Did exactly as described with Ben Lomond (Tasmania), Cape Tourville, etc. For Whistler in BC, while heading for a public campsite, the GPS led me to an almost completed luxury housing estate instead! All the construction workers already gone home and there was not a single resident in the half completed estate. Had the entire hundreds of acres of luxury housing estate all to myself. Slept like a baby and the stars in the night sky was fantastic, no urban light sources for miles in the vicinity to spoil the view. Lucky the bears did not come and disturb me.
Have you hiked this trail in Queenstown?
