What is the best beach to visit during our stay in Costa Rica during the first week in September. I was reading about Jaco, Tamrindo, Coco Beach. My group of three are going to split our time between visiting a beach town and San Jose. Our last minute trip is right around the corner. We are planning on doing all the adventure activies first couple of days. ie zip line, rafting, deep sea fishing. What beach town would be best to be based out of for these activites. Any suggestions would be helpful!!
