I volunteered at a girls home attached to an orphanage in Galle, Sri Lanka. I also did a few days at a monastery teaching English to young monks. The girls I worked with were so sweet and well behaved, even though they had experienced some horrible life circumstances. I really felt like a worthwhile experience.
My host family was very welcoming and helpful, and staying with them gave a real insight into daily Sri Lankan life and traditions. I also really enjoyed exploring Galle old town in the afternoons- a really interesting little place, safe and friendly.
