Deciding to volunteer in Zanzibar is one of the best decisions you’ll ever make. But like any overseas adventure, a little preparation goes a long way. Here are 10 things every prospective marine conservation volunteer should know before they pack their bags and head to the Spice Islands.
1. You Don’t Need to Be a Diver (But It Helps)
Most Zanzibar marine volunteer programmes offer full dive training as part of the placement. If you’re not yet certified, you can complete your PADI Open Water qualification while you’re there. Snorkelling skills and a strong swimming ability are all you need to get started.
2. You’ll Need a Visa — But It’s Easy
Most nationalities can obtain a visa on arrival at Zanzibar’s Abeid Amani Karume International Airport or apply in advance online. The standard tourist visa covers most volunteer stays. Always check the current requirements for your nationality before travelling, as rules can change.
3. Vaccinations Are Important
Before travelling to Zanzibar, ensure your routine vaccinations are up to date and speak to your doctor or a travel health clinic about additional recommendations. Hepatitis A and B, typhoid, and rabies vaccinations are commonly advised. Malaria prophylaxis is strongly recommended — Zanzibar is a malaria zone.
4. The Heat Is Real — Prepare Accordingly
Zanzibar sits close to the equator and temperatures regularly exceed 30°C. Staying hydrated, wearing high-factor sun protection, and acclimatising gradually in your first few days will make a big difference to how you feel throughout your placement.
5. Respect Local Culture
Zanzibar is a predominantly Muslim island with deeply held cultural traditions. Outside of beach areas, modest dress is expected — cover shoulders and knees when visiting towns, markets, and villages. Learning a few words of Swahili (“Jambo” for hello, “Asante” for thank you) goes a long way and will be warmly received.
6. The Food Is Incredible
Zanzibar’s cuisine is a fusion of African, Arab, Indian, and Portuguese influences — and it’s spectacular. Fresh seafood, coconut-rich curries, and the famous Zanzibar pizza (a street food staple at Forodhani Gardens in Stone Town) are all highlights. Most volunteer programmes include meals, but you’ll want to explore local restaurants and food markets on your days off.
7. Internet and Connectivity Is Limited in Some Areas
If you’re stationed at a remote research site, don’t expect reliable WiFi. A local SIM card with mobile data is a good backup, and most volunteers quickly discover that spending less time on their phones is one of the unexpected joys of the experience.
8. The Work Is Genuinely Demanding
Marine conservation fieldwork is physically active — long days in the water, carrying equipment, and careful data recording in challenging conditions. It’s also deeply rewarding. Come with a good level of fitness, an open mind, and the understanding that some days the conditions won’t be perfect. That’s field science.
9. You’ll Leave Wanting More Time
Almost universally, volunteers say their only regret is not staying longer. If your schedule allows, consider extending your placement — the deeper your connection to the project and the community, the more meaningful your contribution becomes. A minimum of four weeks is recommended if possible.
10. Your Contribution Genuinely Matters
This isn’t tick-a-box tourism. The reef surveys you complete, the dolphin behaviours you log, the data you record — it all feeds into real conservation science. Zanzibar’s marine ecosystem faces serious pressures, and every volunteer who shows up, does the work, and cares about the outcome is part of the solution.
