We had the elephant trek/monkey show as a free package from our hotel. We wish we hadn't bothered!
The elephants are chained up until they are required for there trek, they have sores and cuts from the chains. The baby elephant is chained up on a foot, if that of chain and already looks stir crazy. The trek takes you round there village which is 1 house and the rest of the area is like a refuse dump!
The guide on the elephants are very nice and friendly.
The monkey show is just despicable, 3 monkeys, all with chains around there next on a very tight leash doing mundane tricks in a petrified state, hated every minute of it.
I would advise to research your elephant trek when coming to phuket, avoid seaview!!
Apparently Siam elephant trek is very good, conservation area.
