It’s probably a good idea to go to Puerto Rico but if you are looking mostly for native fruits Costa Rica has more than any country in the Americas of its size. The way it is situated gives it a plethora of fruits that go from southern Mexico to the south like sapodilla, mamey sapote, guanabana, caimito, and many, many more. Fruits native to the Choco of Colombia can also be found in Panama and Costa Rica. There’s no way that Puerto Rico has more kinds of native or introduced fruits than Costa Rica.
