Cambios

On the first three sections several rivers and high mountain passes need to be crossed. In particular high river-water-levels during snowmelt may make the river crossings difficult and dangerous until December. Therefore leaving before or in early December may put you in risk when crossing rivers or traversing still snow-covered passes. But if you leave after December you may be surprised by the heralds of the winter before reaching the finish of the Greater Patagonian Trail if walking in a moderate pace.

Even if hiking this trail in the recommended season be prepared for [[#Weather|sudden weather changes]] with heavy snowfall, in particular when you are higher up in the mountains. Also rivers can swell anytime after heavy rain.
