Whenever I'm in CC I use either Eloy or Rockey(?) Badillo. Both of them live on Middle st I don't have either of their phone numbers but they are easy to find. I'm not a fly fisherman but they also guide for fly fishing. The site always recommended is for San Pedro not Caye Caulker and does not book for CC. If you know where your staying ask them to get in touch with Eloy for you. He doesn't check his emails very often. Anglers Abroad specializes in fly fishing and is on CC, but I'm not sure whether Haywood books fishing guides.
