Cruises from Islas Guanape
The Guanapes, located 9 km off the coast of northern Peru, are sheer columns of rock jutting straight out of the Pacific Ocean, with not a speck of mainland in sight. There are two main islands (North and South), plus a number of small stony islets. The larger North island is one kilometre long and up to 300 m wide: just a breeding place for birds. Hence the islands are covered with guano (consisting bird poo and dead birds, rich in phosphates, smelling of ammonia); dug out, and sacked for use as fertiliser.
Now the islands are a protected nature reserve area.
