VIN proposes several types of projects (education, construction, health...) from 2 weeks to few months. The staff is quite supportive and helpful. I was togteher with a couple of other volunteers in a host family around 15km from Katmandu. The family was very welcoming and we had a nice project about Education: we were 3 people on the projects going in several schools around the community area. Nepal is a beautiful country but don't forget warm clothes if you go between December and February !!!
