Choose the minimum and maximum time you require travelers to stay with you. That depends on what activities you want help with. Some activities might require volunteers to stay longer (over 3 weeks), because travelers must be trained and adapt to their daily to-dos, like reception and bartending. Other activities ask for a shorter time, like video making, photography, music and arts.
Most of our travelers have between 2 and 4 weeks to travel, so have in mind that fewer people will apply if you request them to stay longer than 4 weeks!
