Welcome to Represa Arenal
Forget for a moment that there are always ecological issues associated with dams and revel in the fact that this one created a rather magnificent lake (it took a village, or two, in the exchange). In the absence of wind, the glassy surface of Represa Arenal (Arenal Dam) reflects the volcano and the surrounding mountains teeming with cloud forest. Crowds congregate to admire the view and snap photos. Unfortunately, there's no convenient place to stop, so you'll often encounter a minor traffic jam, especially at the dam's western end.
