Limestone cave systems kilometers long, stalactactites, dry caves, unbreathable gas pockets, haloclines, spring flow, "minor" restrictions to wiggle through, vertical shafts, line sharing etc. This is a cave diving paradise atleast for a rookie like me.   I posted this video in order to encourage and inspire divers to train to atleast Intro to Cave level certification. This opens up a new world. The video gives a glimpse. Feel free to shut down your lights, lie on your belly, calm down your breath rate and watch this cave video at full HD resolution on a large screen. Please share the feeling of a first time visit to Grotta del Fico at Sardinia.
