The best experience of my life! You can't miss it.
We stayed about 5 mins from the entrance, consider 30 mins to get to the parking area, then you cross the entrance by foot and go down about 500 stairs, make you sure you are there before 7 am, which is the time the swallows started to leave the cave.
We saw about 1 millions beautiful swallows, fly in circles! And also if you stay quite you will see small green parrots flying around, they all flew above us. This lasts about 1 hour.
Make sure you ask about the scheduling before you go, as swallows leave at different times, depending on the weather.
You can also see them in the afternoon, about 4pm.
Its a long way down, but totally worth it!
