The scenery is very beautiful, the nature during autumn looks very calming. There’s over 30 grottoes, each unique, has a very historical feeling and is very worth seeing in person. It does get quite crowded, even if you come to the very opening at 8:30 am, so for the biggest grottoes there were queues that could last from 5 up to 20 minutes. Going during rainy weather was also a bit troublesome as there’s not many places except for the grottoes and little shops/cafes to take cover. The shuttle buses are very convenient.
