We opted against another hike in the cactus valley, and instead we opted for a hike to a hidden waterfall in a gorge. The waterfall hike had cacti on it, but the cactus valley hike didn’t have a waterfall. We think we made the right choice, enjoying the lush river and waterfall in the desert to ourselves.
And boy was the water cold. The water from the waterfall comes from melting slow in the Andes. The water travels underground through an old magma tube created by a volcano, and it dumps out somewhere above the waterfall. The sun doesn’t have a chance to heat the water since it travels underground. The water was painfully cold.
