We are going to Costa Rica for about 12 nights, but based on research and reviews from other people, we want to spend maybe 5 days around the Osa Peninsula? We were thinking of flying into Bahia Drake, maybe spend a day at Isla del Cano and then start trekking into Corcovado. We would then hike for a couple days and then come out at Carate and eventually spend the last day around Puerto Jimenez and then fly back to San Jose from there. I am wondering if you can actually hike from Bahia Drake all the way through to Carate? Some sources I have read say it is dangerous or impossible during this time of year. If that is case, how would I get across to Carate without going all the way around, especially without a car at our disposal? Are the chances pretty good that the hike form San Pedrillo to Sirena will be impossible? Would it be a better idea to fly directly to Puerto Jimenez and come into the park from the East? It just sounds like there is a lot to do around Bahia Drake. Any help would be much appreciated.
