Hi, this place is still very new. You can contact the local tour by visiting website www.wheretogolanta.com for more information. They have join trip to this spot.
The Gilis are not in Bali, they're in Lombok. Google it. Also, they're not the "Gili Islands". "Gili" means "island", therefore "Gilli Islands" = "Island Islands". It doesn't make literary sense. They're just referred to as "The Gilis". (Did I mention they're in Lombok, not Bali?)
Thank you very much for your information. Now I know that Gili is in Lombok, not Bali (Before that I understood that they are part of Bali because people always travel to Bali and Gili together and it is not far from each other). But for "Gili islands" in this case, I called to follow the tour programs. It looks doesn't make sense when you translate it into English. But I think the tour calls Gili Islands because it is easy to sell to the tourists and they mean the Gili Meno, air, and Trawangan. www.gilibookings.com/
