The easiest way in is via a flight to the Liberia Airport and then renting a (4 wheel drive) car, or taxi to Nosara. Eventually the roads turn to gravel on the way to the beach, and there is one point where you cross a river (minus that bridge thingy). There is also a bus that runs from the capital and Alajuela through Nicoya and on to Nosara.
Once in Nosara you really don't need a car to get around, though if you're in a hurry to get from the beachfront to Nosara town proper, a car or other transport is fastest.
If you do want to get around with a bit more freedom, a few local businesses will rent golf carts. This can be a convienent way to navigate. Other than golf carts, some people also use motorcycles, ATVs, or on horseback.

Surf. Playa Guiones sports 2-6 ft waves, but getting past the rough stuff can be a lesson in humility. There are several places to rent boards.

Also, checkout Juan Surfo (he claims this is his real name) at Punto Surf Shop. Nice guy, decent prices and a local character.
