Costa Rica offers ecoadventures for travellers year round. An exotic example is during the months of August through October.
The awesome Leatherback, the world's largest marine turtle, comes to shore to lay it's eggs. The female drags it's almost 1000 pounds slowly from the ocean to a safe place in the sand. There it digs a deep whole with it's rear flippers
and deposits many eggs. Then it returns to the sea. This process can take many hours.
Another species is the Olive Ridley which tend to lay eggs simultaneously, so you can see hundreds of turtles on the same night. This primeval sight will impact you and make for a definitely unforgettable Costa Rica adventure.
These are popular turtle watching areas, hotels here will be able to provide you with a nearby sea turtle watching expedition
