Blue Grotto - Aerial

View from atop grotto around fenced viewing area. Visible at water level are several rock outcrops, the left-most of which accesses pillar with an approx. one meter span. A single 60 meter roped (halfed) will not reach larger outcrop shaded under pillar, but can be lowered from bolts further down the slope (though you'll likely touch water if you don't maintain contact with the pillar). Just be creative.
