I am going to Costa Rica for the first time in a couple of weeks. Probably to Manuel Antonio, Corcovado, Monteverde and Santa Rosa National Parks. If anyone has been recently I would be glad to get any tips of bat roosts etc. I am also looking into the easiest way to get to Sirena station in Corcovado, and if I can avoid a 10km hike I would be delighted. Does anyone have any tips for there in particular, and know of any good guides I could use around Sirena?
