One of the most breathtaking hikes I have been on would most definitely have to be the trek to St Mary's Peak in Wilpena Pound. 14.4km of jagged and unforgiving terrain, scaled with an inflamed tibia is not a fond way to remember such a stunning landscape, yet somehow the day is something I'm rather fond of in hindsight. The near vertical climb is something I could not have done without Tom shoving my ass up the mountainside, even in the searing heat of a fair 38°. However, I did learn three very simple things whilst up there.
1# Always bring enough water
Or you'll end up drinking your partner's 2L bottles, leaving both of you thirsty.
2# Eat breakfast at base camp, and bring lunch
Leading theory as to why I collapsed on the way up, and if you refuse to do this, it will not only leave you trying to steal your partner's water, but also their lunch.
3# Dress for all weather
Let's face it, this is Australia. You may fry on the way up, freeze while you're up there and come out semi sunburnt and soaked in sweat by the end of the day.
