I found a web site for Eco Tours that takes you on walks on the beaches in search of giant sea turtles and then you get to stay at a farm in the hills and participate in the chores.

Thanks,

In case you have not gone on your excursion yet...you might consider going to Panama instead and visiting Finca Dracula. What Gary says is true, seeing orchids like that can really be hit and miss. I recently read that this facilty has a wide variety of local species under cultivation and caters well to tourists looking to learn about orchids in their native habitat. It is like a conservation/propagation/research center. It sounds like a very professional, well run facility and the owner is very knowlegeable about the panamanian orchid flora. You might want to do a search and look into it. I think they also organize guided tours.
