It is relatively an expensive attraction to visit, including foreigners above 65 (as most others do not levy an entrance fee for all above 65). Furthermore, the shuttle from the ticket office to the main gate and return will need to be paid separately. Walking the grounds on both sides of the river to see the grot toes, carvings, temple and garden is easily at least 4 km. There are a lot of stairs if one wants to see the grottoes and carvings up close. I was here in the afternoon on a weekday, but yet the crowd is quite big. It is difficult to appreciate the attraction up close unless one is ready to face the pushing and shoving at most of the significant carvings. One got to have a history liking to appreciate and marvel on the carvings here. Personally, it is a must do bucket list accomplishment for being here. But to have more in depth information about this attraction, I think some professional videographers may do better.
