Do you know about some hidden "flats" in Bavaro.....
.....because they are not there. However, if you contact some of the fishing guys out in PC (Pro's) they can likely at least get you to some spots where you might get to throw some fast sinking taper (from a boat). This is not the Turks and Caicos.....you won't be finding bonefish here...but you can find Snook and Tarpon in the right places at the right time of the year. Bavaro is never the right place for those species however.
Suerte!
