Galapagos Land Iguana

The land iguana species has its origin in a common ancestor with the marine iguana, about 10.5 million years ago. The iguana grows up to a length of 1.5m (5 ft.) and can weight 13kg (25pounds). They are herbivores, feeding mainly on the prickly-pear cactus but eventually would feed on insects and other invertebrates. They reach sexual maturity at around 10 years old and can live up to 60 years.
They lay 2 to 25 eggs, which they burry in sandy areas. These eggs hatch after around 100 days. In some islands, they have interbred with marine iguanas creating a hybrid iguana species. Very little has been discovered from this species but they are known to be almost all infertile and have a very reduced population.
There are two other species of land iguana in the archipelago, the Conolophus pallidus, which is found only on the island of Santa Fe, and the one known as the pink iguana only found in Wolf volcano on Isabella Island.
Same as other reptiles, they need to thermo regulate so they bask in the sun to warm up making a beautiful picture, and usually burry themselves in the night to conserve the heat in the cold season. They are usually found in the trails and around the cactus growing sites. They have developed symbiotic relationship with birds so they can easily be seen with a finch standing on their heads. Since they are very territorial animals, some fights and social dynamics are part of their natural display. There are about 8 thousand land iguanas in the archipelago.
 

• Animal Group:  Reptiles
• Scientific Name: Conolophus subcristatus
• Animal Average Size: 100 - 150 cm
• Animal Average Weight: 11.5 kg

The largest island of the archipelago and is easily recognized due to its shape that resembles a seahorse. Well known for having the second biggest active crater of the world in Sierra Negra Volcano (1.490 m), is located on the west of the archipelago and has one of the richest marine ecosystems. Isabela together with Fernandina are still located over the hot spot, causing volcanic activity until today, making them the youngest islands of the archipelago. Wolf Volcano had activity just last year giving visitors the chance to see how the islands grow and turn into what we know today.
It was formed into a big island mass by six volcanoes that in the beginning were six different islands, five of which are still active. Each one of them is populated by a different specie of Tortoise that used to live in a separated island.
Home of Penguins, Flightless Cormorants, Marine and Land Iguanas and many Marine Birds, Isabela also portrays the picture of the evolving process that these species went through in all different locations of the same island. Named Albermale by the English colonizers, it offers not only diverse ecosystems but also some of the most amazing landscapes and natural sights of the archipelago.
Small human population in the south of the islands. This is one of the four populated islands; about 2200 people live in Puerto Villamil. This town is the result of almost 300 years of interesting human interactions related to military plans and prison breakouts, and today is a welcoming site to explore and encounter the settlements that can tell the story.
Punta Vicente Roca visitor site is the best place to find the famous flightless cormorant. The evolution process that this specie went through can be observed on his behavior and environment on this location, providing evidence to understand Darwin’s theory of evolution. Located on the north side, the head of the sea horse is a very important marine productive area, hit by the Cromwell Current, offers the most extraordinary marine life so it is considered one of the best diving spots of the archipelago. Whales and sharks are often seen in our visits.
Bahia Urbina visitor site is located on the central west side of the island and is the only place of the archipelago where tortoises have been born and are still there, in other words, they are a natural, untouched population. All other have suffered migrations or problems with introduced species.

Visitors sites: Albemarle Point, Arnaldo Tupiza Tortoise Breeding Center, Cape Marshall, Concha de Perla, Cowley Islet, Elizabeth Bay, Las Tintoreras, Moreno Point, Puerto Viallmil, Roca Blanca, Sierra Negra Volcano, Tagus Cove, The Wetlands, Urbina Bay, Vicente Rock Point, Wall of Tears

It is located on the center of the archipelago, the reason why it is the biggest human settlement, with a population of about 19 thousand people. This island is the most developed in terms of human population that started when one man was abandoned and survived in an old scientific settlement as the Course of the Tortoise tells. The highlands of Santa Cruz are one of the biggest green areas of the archipelago; therefore agricultural activities started on the early 40s and grew rapidly from there. The Charles Darwin Research Station was developed in town on 1959 and has allowed scientific research and conservation projects progress. In between the facilities there is the tortoise breeding center which objective is to rebuild an almost extinct population in Española island where only six individuals where remaining. Today, these efforts have restored the population to over one thousand individuals. Also named Indefatigable after the military British vessel,
The largest accessible lava tunnels.  Underneath the ground hundreds of lava tunnels have been formed by different temperature kinds of lava flow. Some of these tubes are several kilometers long and even though most have collapsed with time and erosion, a couple of them are still there to be visited. They offer the visitor the chance to understand why the stories of pirates and treasures are related to these geological formations.
The biggest tortoises in accessible visitor site. The highlands of Santa Cruz have a big wild population of Tortoises, they walk freely around the private and National Park lands. In our visit to this area, one can notice the difference in size from these animals to others in other visiting sites. There are 15 subspecies of land tortoises in the Galapagos, 4 from which are extinct. They present two different tortoise shell shapes, the Saddleback and the Dome shape. Santa Cruz has tree tortoise subspecies that show both kinds of shells and allow visitors to notice the difference and once understand the evolutionary process that shaped them into this giant prehistoric like animals.
This island has six vegetation zones, each one very different to the others. The contrast of the arid or littoral zone located on the base of the island just a few meters from the ocean, and the scalesia and miconia zones, only to be found in San Cristobal and in this island at about 700 meters above sea level, is portrayed by the landscape and the ecosystems. One of the rarest bush forests stands in the center of the island, spread on top of the Twin Craters.
This island also has some of the largest mangrove areas, a very important ecosystem for all marine life and many terrestrial species. These zones are the nursery of most marine fish and shark.
Tortoises, lava tunnels, white-sand beaches and a picturesque modern town Puerto Ayora bring lift to one of Galapagos greenest, most tropical islands.
 
Visitor sites: Bachas Beach, Ballena Bay, Black turtle Cove, Carrion Point, Carrion Point Dive site, Charles Darwom Station, Dragon Hill, Eden Islet, El Chato Giant Tortoise Reserve, Hacienda Primicias Reserve, Village Puerto Ayora, Santa Cruz highlands, Tortuga Bay, Twin craters

Probably the only island in the world without introduced species. Admire astounding volcanic landscapes at a site often perceived as a ‘land without time’.
The youngest island of all, only 300 thousand years and is still active. Is located on the west side of the archipelago; siting on top of the hot spot. During the Galapagos National Park existence there have been 13 eruptions, the last eruptions ocrurred on the 2005 and 2009 and the 4th of September 2017 (eruption of the Cumbre volcano).
It is an unpopulated island.
Because of the lava flow only mangrove zones and pioneer cacti have survived its geological environment. This specie has created one of the most amazing and attractive miniature forests in the world, a place to evidence adaptation skills to the absence of soil.
The land of Dragons: This island has a big population of Marine Iguanas that survive thanks to its adaptation to feeding on algae. This is one of the best places to evidence the features that back in the day, pushed the Iguanas to evolve into marine animals, here you can visit the blackest and biggest iguanas of all visiting sites. Also a population of Land Iguanas inhabit the active crater of the island.
Flightless Cormorant biggest population to be visited. This island is home for this famous bird that lost his ability to fly because in his environment it wasn’t needed. This bird adapted to food availability being underwater so it developed amazing swimming and diving skills. To visit this colony is to evidence the evolutionary process alive.
Magical light: Its geological nature gives this island a very special light due to its reflection on the minerals and ground, it portrays a polarized picture of reality. It has a very distinct atmosphere from any other location in the archipelago.

Visitor sites:
Cape Douglas, Espinosa Point, Mangle Point

This small island is one of the most important fishing sites for Marine Birds. This place is the reason for many travellers and ornithologists to observe the spectacular and diverse amount of birds of the Galapagos. The visit site is located next to the nesting area of Frigate Birds, both Magnificent and Common, that rest on the trees along the whole year. Witnessing the mating dance of the Blue Footed Boobies is also one of the highlights of the experience. There is additionally a Palo Santo forest that spreads on the south shore of Seymour where birds nest, and offer a spectacular view of the channel formed in between Bartolomé and Seymour. It is an unpopulated island.

Its formation is related to an uplifting of the underwater layer that resulted in a very eroded flat rock surrounded by risks. Here, the marine base is still evident, giant rocks and shells are found everywhere.

Hundreds of sharks such as the Tiger Shark, Galapagos Shark, Reef Shark and others, swim by the shore of this island.  The Upwelling Phenomenon caused by the cold currents, enhance the marine diversity on this snorkelling and dive area.

 Animals: frigate birds, blue footed boobies, sea lions, marine iguanas, swallow-tailed gulls, snakes, herons, hawks, sharks, rays

Plants: Palo Santo, Opuntia

Discover seabird colonies and witness up close and personal, the most intimate courtship, breeding and nesting behaviors.

A walk thru this wonderful small island North Seymour

Bartolomé Island is one of the smaller and geologically younger in the Galápagos Islands. It is located slightly east of Santiago (also called San Salvador or James Island) and has a size of 1.2 km². It is named after Sir Bartholomew James Sulivan of the Royal Navy. The highest point on the island is 114 meters. Special attractions are the beaches, the Pinnacle Rock, , which can often be seen in photos of Galápagos, as well as Galápagos penguins and fish stocks.
 
Most important point of visit: 114 meter high hill with a fantastic view and a very beautiful beach with a view of Pinnacle Rock

One of the smallest and, depending on the season, most colorful islands. Find sea lion colonies, land and hybrid iguanas and countless birds soaring by the cliffs. It is an unpopulated island.

These islands are interesting formations without a volcano resulting from an uplifting from underwater. Conformed by two islands, one flat and the other inclined, they create very special ecosystem dynamics. North Plaza is visited only with scientific and conservation purposes.
The biggest Land Iguana population that can be visited. There is a big ecosystem formed of Cactus Opuntia that holds a population of Land Iguanas, the smallest ones of the archipelago. The trip around South Plaza place allows the visitor see the whole population and to notice how this animals survived in this and other similar environments when they arrived and established. Rarely a hybrid of Marine and Land Iguana can be found on the trails
The walk begins with an impressive cactus forest surrounded by sea lions, land and marine iguanas; as we reach its highest point 82 ft (25 m) be on the lookout for tropicbirds, Nazca and blue -footed bobbies and swallow-tailed gulls.
In South Plaza there is a large colony of the smaller sized land iguanas. The population is approximately 300 individuals. They feed on all kinds of vegetation, but during the dry season, they survive on the fruits and flowers of Opuntia cacti. Due to their proximity with marine iguanas, this is the only place on Earth where we will find the Galapagos hybrid iguana.

Activities: 2-hour 15 min hike
Highlights: Red island due to its vegetation made up of sesuvium, a largest colony of sea lions, the unique landscape of a cactus forest, hybrid iguanas, Nazca, blue-footed boobies, swallow-tailed gulls and red- billed tropicbirds.
