While the 500m dive along the highway large eroded tunnel isn't too interesting, the destination is all the more so: Xich Ha Tunich, supposedly the world's largest underwater stalactite, measuring at least 8m according to my depth gauge, starting just below the halocline at around 11m down to about 20m. This giant drip stone is not just big though, it's also really beautifully formed.

As we got near the water, Miguel noticed a
Turquoise Browed Motmot, which I only got to see thanks to my camcorder's 10x zoom. As it turned out, that would be the last picture it took for me.
