Combining volunteering with tourism may seem like a good idea on the surface, but it is usually an excuse for a tour provider to overcharge participants with limited skill sets who think they have something to offer to a poor rural village because they are travelling from the U.S. or another first-world country. Like missionaries, voluntourists typically disrupt local traditions, take business from local workers and leave before the job is finished. And when that job is finished, it is often a poorly built well, school room or orphanage. However, it's not always a nightmare. Skift spoke with Ethan Gelber, editor of "Adventures Less Ordinary: How to Travel and Do Good" about what happens when the reality of volunteerism matches the dream.
