It is called Kok Chang(Chang is Elephant in Thai). If you google it you will find an extensive report that Cathy, who posts on here has done on virtual tourist. There is also some you-tube footage to look at. It is very easy to find, if you ask your taxi driver to head towards kata viewpoint which is about 5 minutes from Kata beach, you will see all the elephants close to the side of the road on your left. Another place nearby that is a good lunch stop is the After Beach Bar. It is close to KOk Chang on the right hand side of the road and the view is to die for and the food is good too.
On our first trip to Phi-Phi we were on a day trip, got marched off the boat into a hotel for a buffet lunch and were then told we had 90 minutes to explore this beautiful place before the boat left. We decided to turn it into an overnight stay and paid 600 baht for a bungalow on the beach and didn't leave until the last ferry the next day. It was the hightlight of the trip. We had accomadation in Phuket but still thought it was a worthwhile investment to stay the night. It was great to listen to reggae music and watch fire twirling shows and then to wake up at 6 am and go swimming when we were the only ones on the beach. If you are to do the day trip you may well feel the same way when you get there that we did. If so, tell your tour guide to find you a place to stay and you can continue with the tour program after lunch the next day.
