If you want to go golfing, you will have to come back down from El Valle de Anton to the playa communities and there is atleast four or six golf course over there that you can choose from. That will be from Coronado all the way to the JW Marriott. These golf courses are all pretty good. Many people say that the Manta Ray Golf Course in Decameron is one of the best although the Vista Mar has a new golf course that is really great. The golf course in JW Marriott that was designed by Jack Nicklaus is hard to beat.
You do not have to be a member to get into these golf courses. The only difference would be the price. The cost would depend on things like if you would be renting golf carts or clubs but it would probably be around US $100.
