We have already made two trips to CR, studying the different areas for possible retirement. This year we spent 3 weeks, starting at Uvita and moving every 3-4 days up the coast, as far north as Tamarindo. Many of the beaches were empty,and we were told that many of them have bad undertows that are very dangerous. One area that we were at, the owner of the house we were looking at mentioned that in the past year they had lost 52 people to undertows. Which are the best and Safest beaches on the Pacific side, and are there good areas on the other coast (we did not get there)?
