>>2538348you'll need a shitload of water, at least double the recommended amount. Being in the desert, hiking, and being on drugs all drastically increase how much you need to drink.
Other than that make sure you have good hiking shoes, protect yourself from sunburn with clothing, bring enough to keep you warm overnight, easy food since you'll be high for a significant portion of your ((trip)); I'd recommend picking up a big box of granola bars. Some first aid (in case you scrape yourself up), and a way to call for help (in case you really fuck up).
I'd also recommend looking into local wildlife so you can avoid being envenomated.
Oh and a headlamp.
