| Bolaños Island is an oval-shaped
rocky mound, 81 meters high, that lies 1,5 kilometers off Punta
Descartes, on the northwest region of the country. Its rugged
terrain consists of numerous layers of sedimentary rock that are
approximately 40 million years old. |
| |
|
| The scarce vegetation is made up of stunted forest,
which is very thick and difficult to penetrate. It grows
almost two meters high on very rock soils with very little organic
material. The forest, which completely looses its leaves
during the dry season, consists mainly of paira and some medium-sized
trees, such as fraginipani and lancewood. |

Bolaños is especially important for the conservation
of seabirds. It protects one of the few known nesting sites
in the country for colonies of brown pelican and also it's the
only nesting site discovered to date for the magnificent frigatebird. |
| |
|
| There is a white, sandy beach at the eastern tip
of the island with mounds of seashells and clams. At low
tide its possible to walk round the island and gives visitors
a chance to glance at several species of crab that live and mate
here, specially the large sized land crab. |
