Here is a view of the sand and beach in the middle of Tamarindo beach. Tamarindo has a classic, broad, gently sloping, crescent shaped beach, lined with palm trees, and warm ocean waters. Those ingredients make it exactly what a tropical beach should be, in my opinion.
Yesterday I showed one of the two beaches at the Four Seasons Papagayo Resort up the coast from Tamarindo. I have posted this photo today in part so that you will be able to make your own comparison of the beaches.
Incidentally, peaking up above the trees in the center of this photo is the new condo building that is part of the Diria Resort complex in the middle of Tamarindo beach. My wife and I have a condo in that building as well as a condo right on the ocean in the Playa Langosta residential part of Tamarindo.
