Though smaller than Ireland, Costa Rica boasts an amazing biodiversity. With more butterfly species than the whole of Africa, more bird species than Europe, its precious tropical rainforests harbour over half a million plant and animal species. Small wonder that about a quarter of Costa Rica is protected nature reserve or national park. From Puerto Limon shore visits offer an opportunity to journey inland to the picturesque capital of San Jose or to see more of its rich widlife and exotic scenery.
