Best Place for Diving in Colombia: Malpelo Island Flora and Fauna Sanctuary

On the Pacific Ocean, 507 km west of the port of Buenaventura, is the island of Malpelo. It is the only oceanic island of the Pacific Ocean and belongs to the marine corridor of the eastern Pacific Ocean with 11 emerged islets.

The charm of Malpelo lies beneath the surface of the sea. Thanks to its location and great variety of marine flora and fauna Malpelo is among the 5 most beautiful and exotic places in the world to practice scuba diving.

The characteristics of the marine environment are strongly influenced by the type of currents that run through this area of the Pacific. Malpelo is the point of confluence of different and important currents of the Pacific Ocean. 

The encounter between the cold currents of the southern hemisphere and the warm equatorial currents makes its waters very rich in nutrients. Because of this, Malpelo is home to an incredible amount of fauna: hundreds of Green Moray Eels that swim in open waters, schools of barracudas, turtles, dolphins, manta rays in solitary and in groups, rays, longfins, and huge schools of mackerels.

Malpelo is also the sharks paradise, and this is the main reason that makes Malpelo a unique place in the world, with large concentrations of Silky Sharks (Carcharhinus falciformis) and Hammerhead Sharks (Sphyrna lewini), among others.

Discovering Malpelo Flora and Fauna Sanctuary

The Malpelo Flora and Fauna Sanctuary is located on the unique submarine volcanic mountain range, Dorsal de Malpelo. The highest point is Cerro la Mona 300 meters above sea level, this marine mountain range has a length of 150 miles and 50 miles wide.

Voluminous eruptions of basaltic lava gave birth to this island. The islets that surround the island seem to be the result of erosion processes caused by the waves, causing them to be lifted by tectonic effects. This process forms terraces known as “Strath Terraces”.

Malpelo Flora and Fauna Sanctuary was declared a protected area in 1995 and has had 3 expansions in the years 1996, 2006 and 2017 with a total of 1.7 million miles.

In 2005 it was named an Important Bird Conservation Area (IBA) by BirdLife International and the Alexander Von Humboldt Research Institute. In 2006, UNESCO declared the sanctuary a Natural World Heritage Site, and today it is a Mission Blue hotspot. 

Malpelo Flora and Fauna Sanctuary has one of the most important coral formations of the Colombian Pacific; the marine fauna is very varied on the island, and in this sanctuary you can find 2 species of starfish endemic to the country. In addition to this, one of the most important hammerhead shark breeding areas in the world is located in Malpelo Flora and Fauna Sanctuary.

Unfortunately, the sanctuary is constantly harassed by illegal fishermen, which mainly affects hammerhead sharks and hawksbill turtles. In addition, overfishing in zones of influence within the protected area’s limits, such as for tuna, can reach alarming numbers, endangering the decline of the tuna communities.

The Malpelo y Otros Ecosistemas Marinos Foundation, is in charge of promoting the protection and care of marine areas, especially sharks, so that they have a safe habitat for their reproduction. They work together with the national parks system and the national navy.

How to get to Malpelo Flora and Fauna Sanctuary


The only way to access the sanctuary is by sea, after a 36-hours open sea journey from the city of Buenaventura. Take a 145- minutes flight from Bogotá to Alfonso Bonilla Aragón International Airport (CLO) at Palmira city. Once at the airport, take an approximately 3- hours ride to Buenaventura.

What to do in Malpelo Flora and Fauna Sanctuary

Diving and snorkeling

The sanctuary has the following areas for these activities: La gringa, Escuba, Los Reyes, Los gemelos, Sahara, Vagamares, El arrecife, La nevera, Monster face, El mirador, El Freezer, Aquarium, Naufragio wall, Bajo del ancla and Bajo del Monstruo.

These areas have the optimal conditions for a unique experience. You must keep in mind that if you want to do these activities you must have previous knowledge.


The biological component in the terrestrial environment of Malpelo Island is represented by algae, lichens, mosses, some grasses, shrubby legumes and ferns. Seabirds provide guano that acts as fertilizer along with the rain to generate a food source for the invertebrates that inhabit the island.

Ants such as the trap jaw ants (Odontomachus baur), which is considered to have been introduced to the island by man, can be found throughout the sanctuary. It is also possible to find a new species of beetle from the Platynus genus, which is unusual and can be found in Colombia and Ecuador.

On the island, it is also possible to observe the terrestrial crab Johngarthia malpilensis, which is also endemic to the island. Besides this, several other species of crabs also live on the hard substrates, and there are around 270 species of gastropods, 60 of bivalves, 3 of cephalopods, 2 of Scaphopods, and 6 of Polyplacophorans.

Four species of reptiles inhabit the sanctuary:

  • Anolis agassizi, from the equator, feeds on the remains and food waste of seabirds.
  • Dactyloa agassizi is one of the island’s endemic lizards, greenish in color. It feeds on insects and crabs.
  • Diploglossus millepunctatus is also an endemic lizard of the island. Its diet is based on the remains of seabirds and in case of food shortages they can break their eggs and consume them together with the dead hatchlings.
  • Phyllodactus traversalis, known as the geko lizard, joins the sanctuary’s endemic species. It has nocturnal feeding habits based on insects, but during the day it takes refuge in rock crevices.

Malpelo has a wide variety of marine birds, making it an excellent place for bird watching. The bird with the largest representation is the Nazca booby (Sula granti). A third to a quarter of the total breeding population of this species worldwide nests in the Island of Malpelo.

The Biological Component in the Marine Environment

You will see different specie in the rocky walls of Malpelo depending on the depth. From 3 to 6 meters the walls are covered by sponges and some corals, such as the Tubastrea aurea. After 27 meters it is possible to see filamentous algae and violet hydro corals.

In the depths of the sanctuary there are submarine terraces divided into 4 sectors; the slopes of these sectors are the areas where the coral communities are most present. The four sectors are located as follows:

  • “El Arrecife”, it is the most extensive and is located to the northeast of the island.
  • “Pared del Náufrago” (Castaway’s Wall), located to the northwest.
  • “La Bahía de la Nevera” to the west, and “El Bajo de la Nevera” to the southwest.
  • “El Bajo de Junior” to the southwest.

The sanctuary has identified 390 reef fish species and 5 of these species are endemic: Halichoeres malpelo, Axoclinus rubinoffi, Lepidonectes bimaculta, Chriolepis lepidotus, and Acanthemblemaria stephensi.

Pelagic fish, mammals, and sea turtles aggregate in the sanctuary, and it is considered a passageway for migratory species such as tuna, which feed in the sanctuary’s environment during their migration.

There are two species of sharks that can be seen during the visit: hammerhead shark (Sphyrna lewini) and Galapagos shark (Carcharhinus galapagensis). The cleaning zones in Malpelo are inhabited by the barberfish (Jhonrandallia nigrirostris), the king angelfish (Holacanthus passer) and juveniles of mexican hogfish (Bodianus diplotaenia).

Due to the large number of larvae present in the sanctuary, it is possible to see whale sharks (Rhincodon typus) and manta rays (Manta birostris), which can be frequently sighted along with communities of common bottlenose dolphins (Tursiops truncatus).
