My husband and I are planning a trip for January 2007 and are avid hikers, but have never been to Costa Rica.
Our big choice is whether to hire Osa Aventuras for a 4-day hike from Los Patos to Sirena to San Pedrillo, where we'd see the whole park and the scenic areas near Drake Bay;
OR whether to save money and do a self-guided hike from Los Patos to Sirena to Carate (avoiding the problem rivercrossings to to Drake Bay).
Any recommendations or suggestions??
