Staffs are the best. Shout to my tour guide, Mas Agus. They have options of Short, Medium and Long Trip with long trip maximum duration is 2 hours. Unless you go with toddlers, choose the long trip. Beautiful views, interactive explanation by guide, and the laughters from going along strangers in group are the main plus points. Very recommended program. The contact number here in traveloka need to be updated though, cek their IG page too.
