At the very west end of Tamarindo beach where the land juts out into a peninsula there is a small cliff called SanFrancisco point, or, locally Punta San Francisco we often go to enjoy the sunset.
It's amazing, popular and free....
It faces due west. We often go around 4:00PM with some snacks and a few drinks. One time recently there was a group of young folks from Denmark. When the sun started hitting the horizon they huddled into a circle and started singing. How cool. Enjoy, Rob
