Volunteer travel, volunteer vacations or voluntourism is travel which includes volunteering for a charitable cause. Voluntourism often involves extended stays in remote destinations, with significant price tags. With these high barriers to access, many travellers may consider volunteer vacations out of reach. 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.
There are also other types of travelling that engage people with scientific research and education to promote the understanding and action necessary for a sustainable environment. Participants cover a fee that would include expenses on the different sites worldwide, and engage in projects according to their interest or location
