I've been told by word of mouth that all foreigners now must have a guide at all times to enter any national park in Ecuador. This rule doesn't apply to Ecuadorian residents in groups of 5 or less. Does anyone know more information about this new change or can at least confirm it? I was planning to go to Cajas NP sometime soon, but not if I have to pay a guide to hold my hand. I'm liking the government here less and less.
