Conservation volunteer work

[brendanrtw]

My girlfriend and I are thinking about doing some volunteer conservation work somewhere next year for a few months. I know there are tons of site that facilitate this kind of thing, but we are a bit worried that we might pick one which is more focused on the sun and beaches and less on the actual research itself. I've seen a few sites, and some of them appear quite commercial.

Has anyone had any experiences ... positive or otherwise that they'd like to share, or perhaps make a recommendation?

Thanks

Thanks!
