The waterfall apparently comes from the melting snow and glaciers accumulated from the imposing Fitz Roy Massif well behind the charming town of El Chaltén. I believe it's 20m in height. The falls faces east so it gets morning light. We were here in the late afternoon when everything was in shadow so we could take long exposure photographs. Had we come earlier in the day, we might've had to contend with shadows which would've made for terrible photographs. Also, I'm sure its flow diminishes over time as the Patagonian Summer progresses.

We were able to get decent direct views of the waterfall from the end of the trail as well as more angled (but somewhat suboptimal) views from a steep scrambling path that went higher up the cliff alongside the falls. I recalled having to do a little bit of skirting the stream to get the photo you see at the very top of the page.

The walk to Chorrillo del Salto was about 3km one-way (or 1 hour) from town, but we hired a car and got closer to the trailhead. So we only spent about 30+ minutes of walking in each direction. Actually, we stopped the car at the wrong place (about 800m before the actual car park) so the amount of walking could be even shorter than what we've done to get to the falls. We certainly could've saved ourselves a bit of time and effort by simply paying better attention to the signs.
