Managed to stumble across this place nearly a year ago, an elephant sanctuary, homestay, nature appreciation centre all mixed up and set in beautiful scenery. Have been back four times now and having more fun each time. See their website for all the info.

Expect to get wet at least twice per day as you take the elephants for a bath, and sweaty as there is always some work for you to do, helping in the vegetable garden, or gathering food for the elephants (they eat a lot).
