Volunteer travel, volunteer vacations or voluntourism is travel which includes volunteering for a charitable cause. In recent years, "bite-sized" volunteer vacations have grown in popularity. The types of volunteer vacations are diverse, from low-skill work cleaning up local wildlife areas to providing high-skill medical aid in a foreign country. Volunteer vacations participants are diverse but typically share a desire to do something good while also experiencing new places and challenges in locales they might not otherwise visit.
