Aside from international volunteering agencies, there is not a lot of scope for volunteer work in Cyprus. You can check out the following.
- Grol Garden (www.grolgarden.info) Organic permaculture garden in Northern Cyprus which accepts local and international volunteers.
- Transitions Abroad (www.transitionsabroad.com) A good website to start your research.
- Turtle Conservation Project (www.seaturtle.org/mtrg/projects/cyprus/volunteer) Voluntary opportunities for the marine-turtle conservation project on the Karpas Peninsula.
