Join our award-winning dive expeditions to Madagascar!

Based in the remote fishing village of Andavadoaka on Madagascar’s southwest coast, our dive expeditions offer volunteers from around the world a unique opportunity to get involved with Blue Ventures’ marine research and community conservation work.

Join our team surveying one of the Indian Ocean’s most extensive coral reefs, and contribute to our efforts supporting coastal communities to conserve these spectacular ecosystems. From sea cucumber farming to environmental education with local children, expedition volunteers are immersed in the full breadth of Blue Ventures’ innovative and integrated programmes.

From gap year students and university graduates to career breakers and retirees, our expeditions attract a diverse range of people from around the world, who share an interest in diving with the purpose of supporting our marine research and conservation work. You will participate alongside Malagasy scholars who we support to allow them to join our expeditions and develop the skills and experience required to take a more active part in the conservation and management of Madagascar’s marine resources.

You’ll be immersed in Madagascar’s beautiful coral reefs and vibrant coastal culture while assisting with our rigorous underwater research and gaining skills and qualifications. Expedition volunteers are at the heart of everything we do and we’d love to have you join us! You can read stories of past volunteers as well as our Beyond Conservation blog to learn more.

Challenging, exciting, rewarding... an expedition with Blue Ventures will change your life!

When I look back, I can barely remember the person I was before I came to Andavadoaka. It has been a most wonderful and educational experience for me. I hate to have to go.

Being able to identify so many coral and fish species has opened up an entirely new underwater world to me!

All of our volunteers complete an intensive two-week science training programme run by our field scientists at the beginning of each expedition, involving numerous snorkelling and diving excursions as well as informal lectures, small group discussions and practical exercises on coral and fish species identification.

Both qualified and non-qualified divers are welcome to join our expeditions. All divers must be trained to at least PADI Advanced Open Water or equivalent, and we provide training to this level as part of the expedition fee. Dive training is carried out during the first two weeks of expeditions, so that all volunteers are qualified to participate in underwater surveys once they have successfully completed their science training.

In your time at our base in Andavadoaka, as well as relaxing in a hammock by the beach you can learn to sail with local fishers, explore the baobab forest, or take a picnic out to one of the nearby islands – bliss!

And counting… We’re extremely proud to have supported so many brilliant volunteers who have actively contributed to our research and conservation work in Madagascar!



We’re delighted to welcome volunteers from all over the world to work with us in Madagascar.


Survey hours

On average you’ll do 1-2 dives per day after your dive and science training is complete. You’ll be diving up to 5 days a week (weather dependent) so you’ll clock up a lot of underwater time!

Volunteer Guide

Our expeditions take place by the village of Andavadoaka, which lies on the edge of a shallow lagoon, protected from the open ocean by a series of fringing and submerged coral reefs, providing a vital resource base for local fisheries.

Our team and volunteers are based at a hotel-restaurant called Coco Beach, with comfortable wooden eco-cabins overlooking the white sandy beach and turquoise blue sea beyond.

Every six weeks a new group of volunteers arrive at our site, ensuring year-round sustainability of our marine research. We host an average of 12-14 volunteers per expedition, and we never have more than three volunteers per staff member to ensure you get the training and support you need.

Our commitment to high quality accommodation and food and our ratio of staff to volunteers makes us different from our competitors. If you want to call, email or message us, there are lots of ways to contact us.

Find out about flexible start date arrangements

We understand that volunteers are not always available at the time when an expedition is scheduled to begin or for the full 6 weeks. We therefore offer mid-expedition start dates, and further flexibility for start and end dates can also be accommodated. Our mid-expedition start dates for 2015 are as follows:

Actual expedition start date Flexible expedition start date
4-Jan 11-Feb or 25-Mar
17-Feb 24-Feb or 10-Mar
1-Apr 8-Apr or 22-Apr
16-May 23-May or 6-Jun
29-Jun 6-Jul or 20-Jul
12-Aug 19-Aug or 2-Sep
27-Sep 4-Oct or 18-Oct
11-Nov 18-Nov or 2-Dec

Please note the following regarding our flexible dates:
If you decide to join an expedition late we are unable to provide you with the same level of staff support and introductions when you arrive in Toliara and at our site as you would otherwise receive on the scheduled dates. We will do our best to make your experience as smooth as possible but it is likely to be slightly more challenging so we advise you to stick to scheduled dates if possible.

If you join late or leave an expedition early, you will be responsible for your transfer costs between Toliara and Andavadoaka. We can arrange a 4×4 vehicle with a driver for you, and the cost is approximately £130 each way, which can be shared with anyone else travelling at the same time. We do our best to coordinate journeys with other volunteers and staff to reduce the cost, but you should be prepared to pay the full amount if this is not possible.

Madagascar Expedition Costs

Expedition prices vary according to your current diving qualification and length of stay in Andavadoaka. Half of our volunteers have never dived before and our PADI dive courses represent excellent value for money.

How much extra money should I bring?

While at our base in Andavadoaka there will be little opportunity to spend money – one of the benefits of running such a remote site! We recommended budgeting around £50 per week for things like drinks, snacks and telephone/internet credit. The women’s association in the village also sells a variety of inexpensive gifts and souvenirs, including necklaces with marine life pendants fashioned out of local silver coins. There is no ATM (!) in the village of Andavadoaka, where you will be staying for 6 weeks, so all spending money should be withdrawn prior to the beginning of the expedition.
