Kayaking for Irrawaddy Dolphin

Nope, I didn't get the river wrong, a sub-population is also found in the Mekong. The elusive creatures make their appearances only at the mouth of the river, in brackish waters right on the border with Cambodia. And when they do, only fleeting glints of their shimmering backs as they surface to breathe through their blow holes. Only a few dozen left here, but apparently recent conservation efforts have been bearing fruit.
