We are planning our 3rd trip back to Costa Rica for this January. I have always wanted to make the drive up the southern pacific coast of the peninsula but have thus far been convinced not to by various reviews and car rental websites. I am wondering if anyone has made this drive during the dry season and if it is difficult to cross the rivers in an 4wD SUV then. Also if it is somewhat difficult could anyone recommend a tour or guide who could take us? I am interested in visiting some empty landscapes and seeing some wild places I haven't seen yet.
