2. The Blow Hole
The blow hole is a natural rock formation created by the erosion of the million of years of waves pounding against the rock. Think of it as a snorkel that when it gets hit by waves canalizes water pumping it over 10 meters high.
This is considered by many a tourist trap and rightfully so, as this is a must stop for all the tours doing the city tour. If you hate the crowds and the pushy vendors this venue is definitely not for you.
