About Program

Eco2 Diving offers a small-scale, hands-on coral reef restoration program in Mikindani, southern Tanzania, focused on personal involvement and field-based marine conservation.

The program is open to everyone, including non-divers, with close supervision, proper training, and progressive skill development throughout the experience.

Based at an active PADI and SSI dive resort, volunteers combine scuba diving with real fieldwork such as coral nurseries, reef rehabilitation, underwater monitoring, and data collection. Education is central to the program, covering reef ecology, marine conservation principles, restoration methods, and responsible diving practices. Activities take place both underwater and on land, creating a meaningful and well-rounded conservation experience for each volunteer.

The project remains intentionally personal and impact-driven, as an alternative to mass volunteerism.

Program Highlights

  • Human-scale, field-based coral restoration program
  • Open to non-divers and certified divers
  • Hands-on marine conservation, in and out of the water
  • Strong focus on training and meaningful participation
  • Discover Mikindani, an authentic Tanzanian village away from mass tourism

Limited spots available throughout the year

Program Impact

+ Direct Reef Impact
Volunteers actively contribute to coral reef restoration through coral nurseries, coral planting, and underwater structure installation. This hands-on work directly supports the regeneration of reefs damaged by destructive fishing practices, helping restore habitat complexity and marine biodiversity.

+ Community-Based Conservation
Working side by side with local staff and community members, volunteers take part in real field-based conservation activities both underwater and on land. Through shared work, education, and knowledge exchange, the project strengthens local understanding of reef threats and fosters long-term stewardship of marine ecosystems.

+ Be the Change Yourself
Beyond fieldwork, the program promotes a lifestyle compatible with marine conservation. Through education, training, and hands-on experience, volunteers develop lasting awareness, skills, and responsible habits that continue to influence how they dive, travel, and interact with the ocean long after they leave.

Discovering Mikindani Above and Below the Water

I arrived knowing almost nothing about coral restoration and, as a history teacher, I initially found myself asking more questions about Mikindani's past than its reefs. That quickly changed. Learning to dive opened up an entirely new part of the place I was visiting, and working on the nurseries gave those dives a purpose. I loved the contrast between spending the morning underwater and then talking with people or exploring the town afterwards. There were plenty of moments when I looked completely incompetent during my dive training, which kept everyone entertained, but that was part of the experience. By the end, I felt I hadn't simply participated in a conservation program; I had discovered Mikindani from two completely different perspectives.

What was your funniest moment?
My students would have enjoyed seeing their history teacher learning to dive. During one training session I was concentrating so hard on everything that I completely failed to notice everyone signalling that we were going the other way. I happily swam off alone for about ten metres before realising!
Pros
  • The combination of volunteering and discovering Mikindani
  • A small organisation where it's easy to interact with everyone
What other participants should know
  • You need to enjoy quiet places — there isn't much nightlife

Test, Observe, Improve

Because I work in renewable energy, I was already interested in environmental projects before coming to Mikindani. What appealed to me most was the practical, experimental nature of the restoration work. You can have a good idea on paper, but the reef eventually decides whether it works. I enjoyed discussing different methods, observing their limitations and thinking about how they might be improved. I stayed long enough to return several times to work carried out earlier in my visit, and even seeing small changes was extremely rewarding. Conservation here isn't theoretical — you're constantly learning from what actually happens underwater.

What was the most surprising thing you saw or did?
Coral growth ! Over my time here, I was able to see this tiny coral grow over its rope and that was really fabulous. Nature is amazing.
Pros
  • Lots of discussions with the team about the methods used
  • The pragmatic and experimental approach
What other participants should know
  • Local conditions sometimes limit the technical solutions available

The Ocean I Was Afraid Of

It seems slightly ridiculous now, but I chose a marine conservation program despite being genuinely nervous about deep water. I wanted to challenge myself, although during my first ocean dive I questioned that decision! I couldn't descend at first and needed time at the surface to calm down. Nobody rushed me, and eventually I went down metre by metre. A week later, I found myself calmly working on a coral nursery and suddenly realised how far I had progressed. I came because I cared about environmental issues, but the experience became much more personal than I expected. Understanding coral restoration was fascinating, but learning that fear doesn't necessarily have to stop me from doing something is probably the lesson I will remember longest.

What was the most nerve-racking moment and how did you overcome it?
Simply descending on my first ocean dive. I had convinced myself I was ready, then suddenly I wasn't! Nobody rushed me. I stayed at the surface, breathed, tried again and went down slowly. A week later I was working underwater and couldn't believe I'd been so frightened.
Pros
  • Developing a practical understanding of environmental issues
  • The support provided to beginners
What other participants should know
  • You need to accept progressing at your own pace

Meer dan een vrijwilliger, minder dan een toerist

Ik had al veel gereisd voordat ik naar Tanzania kwam, maar ik had nog nooit deelgenomen aan een natuurbeschermingsproject. Wat ik het leukst vond, was de afwisseling. De ene dag hield ik me bezig met duiken of het werken met koralen, en de volgende dag met activiteiten op het land. Als docent vond ik het vooral geweldig om tijd met kinderen door te brengen en te zien hoe milieueducatie een aanvulling kon zijn op het werk dat onder water werd gedaan. Mikindani zelf was ook een belangrijk onderdeel van mijn ervaring. Na een tijdje voelde ik me niet langer iemand die er alleen maar op doorreis was. Ik begon mensen te herkennen en raakte gewend aan het rustigere ritme van het stadje. De accommodatie en levensstijl waren vrij eenvoudig, maar juist dat vond ik prettig. Toen ik vertrok, had ik het gevoel dat ik een paar weken ergens echt had gewoond, in plaats van er alleen maar op bezoek te zijn geweest.

Pros
  • Het nauwe contact met het team en de lokale bevolking
  • De educatieve activiteiten met kinderen
What other participants should know
  • Het comfort is vrij eenvoudig
  • Ik had graag aan nog meer activiteiten met de lokale gemeenschap deelgenomen

Plonger avec un but

Je plongeais déjà depuis plusieurs années lorsque je suis arrivé, donc j'étais familier avec le concept de plonger. Ce qui a changé, c’est la raison pour laquelle je plongeais. Lors d’une plongée loisir classique, on regarde constamment autour de soi à la recherche du prochain animal intéressant ou d’un beau paysage. Ici, je pouvais passer la majeure partie d’une plongée à travailler avec précision sur une toute petite zone. Revenir sur les mêmes sites, reconnaître certaines colonies et observer l’évolution du travail effectué précédemment m’a permis de créer un lien avec le récif que je n’avais jamais ressenti en tant que touriste. Cela m’a également poussé à faire beaucoup plus attention à ma flottabilité et à mes mouvements sous l’eau. Les plongées n’étaient pas toujours reposantes — c’étaient des plongées de travail — mais je les ai trouvées beaucoup plus gratifiantes. Pour la première fois depuis des années, j’avais l’impression de redécouvrir complètement la plongée.

What is your advice to future travelers on this program?
Si vous êtes déjà un plongeur expérimenté, oubliez l’idée qu’il s’agira simplement de vacances plongée comme les autres. Travailler sous l’eau demande des compétences différentes et beaucoup plus de patience. Prenez votre temps, améliorez votre flottabilité et appréciez le fait de plonger avec un véritable objectif plutôt que de chercher constamment le prochain gros animal.
Pros
  • Améliorer ses compétences tout en contribuant au projet
What other participants should know
  • Il faut rester suffisamment longtemps pour vraiment profiter du suivi

Naturbevarelse er ikke en eksakt videnskab

Jeg kom til Mikindani for at få praktisk felterfaring, inden jeg afsluttede mine studier i miljøvidenskab. Jeg tror, jeg havde forestillet mig naturbevarelse som en proces, hvor forskerne allerede kendte den rigtige metode, og de frivillige blot hjalp med at udføre den. Virkeligheden var langt mere interessant. Jeg lærte, at restaurering handler om at observere, afprøve, nogle gange fejle, tilpasse en metode og prøve igen. Arbejdet med koralplanteskolerne og de nye koraludplantninger gjorde miljøvidenskab langt mere konkret, end det nogensinde havde været i et klasselokale. Jeg nød især diskussionerne om, hvorfor én metode kunne fungere anderledes end en anden. Hvis jeg kunne starte forfra, ville jeg føre en detaljeret feltdagbog fra den allerførste dag, fordi jeg lærte noget nyt næsten hver dag og hurtigt indså, at jeg umuligt kunne huske det hele.

If you did this all over again, what's one thing you would change?
Jeg ville føre en ordentlig feltdagbog fra første dag. Hver dag lærte jeg så mange små ting om koraller, dykning og restaureringsmetoder, og jeg blev ved med at tænke, at jeg nok skulle kunne huske dem. Det kunne jeg selvfølgelig ikke! Næste gang ville jeg skrive mine observationer ned efter hver dag i felten.
Pros
  • Masser af læring gennem praktisk erfaring
  • At opleve virkeligheden i et naturbevaringsprojekt i felten
What other participants should know
  • Man skal acceptere, at nogle forsøg mislykkes
  • Jeg ville gerne være blevet længe nok til selv at kunne måle resultaterne
  • Det tager et par dage at vænne sig til varmen

Pobrudzić sobie ręce — pod wodą

Pracuję jako elektryk i zawsze wolałem robić coś własnymi rękami, więc wiedziałem, że nie chcę wolontariatu, podczas którego głównie stałbym z boku i się przyglądał. Tutaj zdecydowanie nie było z tym problemu. Pomagałem przygotowywać konstrukcje, instalować sprzęt i utrzymywać szkółki koralowców. Bardzo podobało mi się to, że mogłem zobaczyć, jak wiele praktycznej pracy wymaga odbudowa raf. Praca pod wodą nauczyła mnie również cierpliwości. Coś, co na lądzie naprawiłbym w kilka chwil, pod wodą nagle stawało się pracą zespołową, wymagającą komunikacji za pomocą znaków i kilku prób! Podobała mi się różnorodność między dniami spędzonymi na morzu a pracą na lądzie, a wolne weekendy dawały dużo czasu na zwiedzanie okolicy, wyjście na plażę albo po prostu odpoczynek. Miałem poczucie, że wykonuję pożyteczną pracę, nie tracąc przy tym wrażenia, że przeżywam prawdziwą przygodę.

What was your funniest moment?
Obserwowanie, jak we czwórkę próbujemy przesunąć pod wodą coś, co na lądzie wydawało się bardzo łatwe do przeniesienia. Każdy miał inny pomysł, nikt nie mógł mówić, a w pewnym momencie właściwie porozumiewaliśmy się już tylko za pomocą wściekłych gestów. W końcu udało nam się ustawić wszystko na miejscu, a potem śmialiśmy się z tego przez całe popołudnie.
Pros
  • Duża różnorodność między pracą na lądzie i na morzu
  • Wolne weekendy na odkrywanie okolicy
What other participants should know
  • Praca pod wodą jest wolniejsza i bardziej frustrująca niż na lądzie

A peek Outside My Comfort Zone

I spend most of my working life sitting behind a computer, so I deliberately wanted an experience that would push me completely outside my normal routine. I certainly found it! I had never dived before and the first few days were challenging. There were moments during the training when I genuinely wondered whether scuba diving was for me. The team was patient and let me progress without pressure. A few days later, I was underwater helping to clean a coral nursery, which felt almost unbelievable. What started as something intimidating became my favourite part of the program. I came home with a diving certification, but the bigger achievement for me was discovering that I could become comfortable doing something that had initially frightened me.

What was the most nerve-racking moment and how did you overcome it?
Taking my mask off underwater during my diving training. I hated every second of it! When I finally managed it, I think I was more proud of that than anything else I did that week.
Pros
  • Learning to dive as part of a real project
  • An experience that really pushed me out of my comfort zone
  • The team's patience while I was learning
What other participants should know
  • The Wi-Fi reminded me several times that I was a long way from home!
