1. What was the most memorable or exciting part of your holiday?

I spent two days on a fact-finding trip with the field scientist, visiting fishing villages in the neighborhood of the project site. It was a great opportunity to see the impact of the marine conservation project on the local communities and how the partnership worked. More than that it was beautiful journey in a dug-out canoe, including one leg at night in an extraordinarily dramatic electrical storm with that evening's supper - a soon-to-be-dead cockerel - hunkered down at our feet. In one village we taught the local kids to sing "Cecilia" by Art and Garfunkel. They, in turn, danced for us to music from a xylophone made out of a few pieces of wood placed on outstretched legs. It was a wonderful two days.

2. What tips would you give other travellers booking this holiday?

Be prepared for an intensive group experience - it was closest thing to Big Brother I can imagine! The site is isolated and you are living in each others pockets, sharing huts with the same people etc for several weeks. Be prepared for basic food and don't expect the best diving in the world. The whole point about this place is that the reef is being over-fished. If you want a diving holiday go somewhere else, if you want to volunteer on a marine conservation project, this is a place that really needs your help.

3. Did you feel that your holiday benefited local people, and minimized impacts on the environment?

Absolutely

4. Finally, how would you rate your holiday overall?

I wanted to stay in a community, get a sense of their way of life and help in some way. I felt it ticked all those boxes and was a lot of fun to boot - even though I was a lot older than most of the other volunteers.
