It hardly gets more challenging than SE Asian jungles at the height of summer. What’s important:

• Water and electrolytes are very important and at the height of summer needs to have added electrolytes
• Take more water than you need and drink early
• We always keep ice and abundant water in the vehicle – ready to be dropped into a back-pack
• Everyone is responsible for their own water
• Coconuts are a fantastic source of potassium (1,200 mg /coconut!)
• Sports drinks are NOT electrolyte replacements as they contain a poor electrolyte balance and way too much glucose.
• Hats, long sleeve shirts, trousers, boots (and gaiters) are essential.
• Gloves are great, they protect from the sun and against the inevitable ants and vines and trees with spikes and spines.
• Do not push yourself, take it easy as it is all too easy to have little capacity left for the unexpected (bushfire, snake bite, injury etc.)
• Wildlife is for observing (see the caption below)
