Island terrain textures?

I apologize if this has been asked many times before or is in the wrong forum but I couldn't find anything through the search bar. Are there any decent island or beach textures for terrain out there? I ask because I'm making a map based entirely on a small island and I don't really think Valve's gamut of textures would quite fit with it.

huh, didn't think about using the Egypt stuff at all. I'll look into it, thanks!
