I had mixed feelings about the elephant safari. On one hand I felt a bit sorry for the elephants but on the other hand it was an interesting experience.
Apparently elephants were used extensively for labour but not that it's not the case anymore, elephants end up transporting tourists and being used for pleasure.
I guess most of the elephants that are used now were bred in captivity.
Favorite thing: We saw a great many elephants on Ko Phuket. Sadly none of them were wild, instead all domestictaed. One hopes they are treated well. Most Thais seem to be in tune with nature and have reverance for living beings. Still it is hard to see an elephant chained in a field.
Fondest memory: All the Elephants! They are everywhere; in downtown Bangkok, Phuket, rubber farms, snake farms, etc etc.
