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

Diversity & Inclusion 💙

Our project operates in a multicultural, international environment rooted in a local Tanzanian context.
We are committed to fostering a respectful and inclusive atmosphere for all participants, regardless of background, while encouraging cultural awareness and mutual respect on the ground.

Impact 🌎

Our approach to sustainability is grounded in long-term thinking and practical action.
We aim to minimize the environmental footprint of our operations while actively contributing to marine conservation through reef restoration, responsible diving, and community-based initiatives.
Sustainability, for us, means ensuring that our activities create lasting benefits without compromising the ecosystems we depend on.
We design our programs with a strong focus on long-term impact, local relevance, and realistic expectations.
Activities are carefully balanced to ensure they support marine ecosystems and local communities without creating dependency or unnecessary pressure.
Ethical impact, for us, means acting responsibly today while preserving the integrity of the environment and community for the future.

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.

Yes, I recommend this program

Great experience! Amazing, exciting, fantastic and funny.

Martha and Laurent are so lovely, enthusiastic about what they are doing, that it's a joy and pleasure to join Eco2dive!
The program is well-balanced and contains several different activities.
I learnt a lot about corals and diving! It was so adventurous to dive in the ocean and see all the beings underwater. Colourful, playful and seemed to be extraterrestrial sometimes! I also liked to talk to the other volunteers and the warm-hearted staff. Thanks to Buruhani, Saidi, Rehema, Jamila, the guards and the guys from the boat. Sorry, to many names :-) I enjoyed to walk around in Mikindani and nearby, talk with the locals and discover some interesting things, like bisi and big baobab trees and monkeys in the jungle.

What was your funniest moment?
A colourful came and swam around me, curious and without fear. He almost swam under the hammer i used to fix nails in a rock to tie corals. :-)
Pros
  • Underwater life
  • Lot of knowledge
  • Lovely people and much more

5 Weeks in Mikindani

In 2025, I took a six-month break from university to see more of the world and gain hands-on experience outside of an academic setting. My goals during this time were to learn as much as possible, meet new people, and - most importantly - give something back to the places I was lucky enough to visit.

Volunteering felt like the most meaningful way to achieve these goals, which led me on a search for the right program. Surprisingly, the biggest challenge was finding ethical amd sustainable volunteering opportunities that aligned with my values and were either within my existing skill set or something I genuinely wanted to upskill into. That’s how I discovered coral restoration projects.

Eco2diving ultimately stood out due to its location, affordability, and strong positive reviews—and I’m very glad I chose it.

The experience exceeded all of my expectations. Martha and Laurent are incredibly kind, passionate people who are clearly dedicated to both conservation and creating a positive experience for volunteers. They’ve built something really special.

The accommodation was very comfortable and the food was delicious, with the half-board option providing more than enough each day. I did experience some very minor plumbing issues, but they were impressively fixed within a few hours 🤯.

One of the biggest highlights of the program was the land conservation education days. These were incredibly engaging and informative, offering a deeper understanding of environmental issues beyond the reef. The strong focus on education meant that rather than simply participating, I learned why the work mattered and how it connected to the wider ecosystem. I left these days feeling inspired, empowered, and equipped with practical knowledge to continue conservation efforts beyond the program.

Another major highlight was the opportunity to progress quickly with certifications. In just five weeks, I earned my Reef Restoration Certification and advanced to an Advanced Scuba Diving license.

The daily schedule was well structured and thoughtfully balanced, with enough time for rest and personal exploration alongside the program’s activities making it possible for me to also maintain some freelance digital nomad work.

On a weekly basis, I did a minimum of three dives, one land conservation day, and a fortnightly outing to support seaweed farming—creating a well-rounded experience that combined hands-on marine work with meaningful land-based education.

Pros
  • Ethical and Sustainability Focused
  • Safety is Prioritised
  • Super Fun
Cons
  • Having to leave 😪

Conservation, diving, and cultural immersion all at once

I joined the coral restoration program in Mikindani looking for an experience that would combine diving with something meaningful, and it exceeded my expectations. From the moment we arrived, the focus was clearly on immersion — not only underwater, but also in the daily life of the village and its surroundings.

The coral restoration activities were well explained, practical, and adapted to what the reef needed at that time.

Laurent, Martha, and the whole team were welcoming, organized, and always available, making everything feel easy and well taken care of. It felt like a real project, run by people who genuinely care about both the environment and the people involved.

An experience I would happily repeat.

What was the most unfamiliar thing you ate?
Chipsy mayai ! This is a chips omelet. Really weird at first, but actually delicious. And best hangover food ever !
Pros
  • Hands-on coral restoration combined with quiet, uncrowded diving
  • Strong cultural immersion and welcoming local team
  • Very welcoming staff, neighbours and village

Can’t wait to go back!

I spent five weeks in Mikindani with Martha, Laurent and the rest of the eco2 team. I had an incredible experience and can’t wait to go back!

I went having never dived before and wanting to learn more about conservation. I did my open water with them and they are fabulous teachers who I felt really safe with the whole time. This programme is an excellent opportunity to learn how to dive because you fit in a lot of diving, so you learn quickly and develop lots of different skills while carrying out conservation. You also have the opportunity to fit in fun dives in an untouched, beautiful environment where you are guaranteed to be the only divers on the site.

The conservation programme is very hands on and covers many aspects, including regular coral planting sessions, making and installing an artificial reef, educational days, beach clean ups, fun dives etc.

While the schedule is full, Martha and Laurent are very supportive if you want to fit in any other experiences such as safari.

The town itself is a quaint historical Tanzanian coastal village and is very relaxing. The accommodation and restaurant is lovely, which was a treat after tiring days of diving!

I cannot recommend this experience more, if you want a hands on personable experience while learning about marine conservation and how to dive!

What is your advice to future travelers on this program?
Make sure you try vitumbua from down the road!
Pros
  • Learning how to dive
  • Learning a lot about marine conservation
  • Relaxed and switched off
Cons
  • There are not so many things to do outside of the programme as the area is quite quiet
  • I was the only volunteer, I did not mind this at all but be aware that you will not be working with lots of other voounteers

Meaningful diving and cultural discoveries

I joined the coral restoration program in Mikindani because I was looking for something more than just recreational diving. I wanted an experience that combined meaningful environmental action with cultural exchange — and this program truly delivered. I learned a lot about coral ecosystems: how to recognize different species, understand their growth, and why they are so essential to marine life. Beyond diving, I really appreciated the cultural side of the program — meeting local people, sharing meals, discovering everyday life in a small Tanzanian coastal village, and feeling part of the community rather than just passing through.
It was intense, eye-opening, and deeply rewarding.

What is your advice to future travelers on this program?
If you are motivated, curious, and genuinely interested in helping the environment while discovering local life, you will get a lot out of this experience.
Pros
  • Fascinating marine life
  • Strong cultural immersion

An active and meaningful way to protect coral reefs

I joined the coral restoration project in Mikindani because I didn’t want to remain a passive observer when it comes to environmental protection. I was looking for a hands-on, concrete way to contribute, and this project offered exactly that.

Laurent, Martha, and the entire Eco2 team are deeply committed to protecting and restoring the local reefs. Their passion is genuine and contagious. The work is real, sometimes physical, but always meaningful. Both underwater and on land, I felt that every effort contributed to something bigger than myself.

What made this experience unique was the balance between independence and teamwork. You are trusted to take responsibility, to learn, and to actively participate rather than just follow instructions. Life in Mikindani is simple, but rich in human connection and purpose. I truly hope the corals we planted will thrive and grow — projects run with this level of dedication deserve to succeed.

Future participants should know that this is not a “tourist” experience, but a genuine conservation project. If you are motivated and care deeply about the environment, this program is extremely rewarding.

What was your funniest moment?
Realising how physically demanding coral work can be — and laughing together after a long day when everyone was exhausted and feeling good about the great job accomplished. It creates strong bonds very quickly.
Pros
  • Genuine, hands-on conservation work with real impact
  • Passionate and knowledgeable team

Best 3 Months!

I decided to go on a gap year after finishing school and found this hidden gem in Tanzania. I was trained to become and scuba diver and have wanted to expand my knowledge on diving ever since. The things one can see at these places are incredible and breath taking. The staff was extremely friendly and help me with any struggles I had over the time I spent there. Would highly recommend for people who want to experience lovely spots on this planet. In addition would recommend you take a good amount of time to stay at this spot to experience everything one can.

What was the most surprising thing you saw or did?
The incredible animals one can see under water. Light giant turtles and dolphins.
