As a volunteer of the European Voluntary Service you are going to live for a long time in a foreign country which means you are going to get to know it very good. Use the time and travel as much as you can. There are a lot of great offers for volunteers to travel cheap (discounts with the eruopean voluntary card, blablacar, cheap hostels etc.)
A few time ago we realized that we travelled a lot but forgot to do some sightseeing in Madrid, the city we live. So yesterday we decided to do a free tour which was great.
Use the great oppurtunity and become a volunteer!
