The Galápagos land iguana is a large, yellowish, endemic lizard that lives on land and feeds mainly on Opuntia cactus — unlike the marine iguana, which feeds in the sea. Several islands hold it, some naturally and some through reintroduction. A separate pink land iguana survives only on Isabela's Wolf Volcano.
The Galápagos land iguana is a large, yellowish lizard found only in the archipelago. It lives on land and eats plants. It is one of four iguana species here, a group that also includes the pink land iguana and the marine iguana.
The clearest difference is where each one feeds. The marine iguana is the only lizard in the world that feeds in the sea, grazing on algae underwater. The land iguana stays ashore and depends on cactus and other plants. Both are endemic reptiles, but they live in entirely different niches.
South Plaza is where the two overlap. It is the only place land and marine iguanas are known to interbreed, and its land iguanas are the smallest in the islands.
Land iguanas live on Isabela, Fernandina, Santa Cruz, Baltra, South Plaza and North Seymour. But that single list hides three very different histories: some populations are native, some were returned after local extinction, and one was moved by people from another island.
Fernandina is the youngest and most pristine island. It never had introduced mammals, and it holds the largest and densest marine and land iguanas; its single visitor site is Punta Espinoza. Isabela is also native land-iguana range and the sole home of the separate pink land iguana. Santa Cruz, South Plaza and Santa Fe carry native land iguanas too, and Santa Fe’s is a distinct endemic form.
Baltra’s land iguanas went extinct around 1954 and were later reintroduced. Santiago’s were reintroduced in 2019. North Seymour is different again: its land iguanas are not native — they were brought over from Baltra in the 1930s. North Seymour is otherwise best known for the largest magnificent-frigatebird colony and prime seabird breeding.
The pink land iguana is a separate species that survives only on Wolf Volcano, Isabela — around 350 individuals, and Critically Endangered. Isabela is its only home.
In practice, travellers cannot see it. Its Wolf Volcano range is permit-restricted and closed to general visitors, and the National Park sites on that side of Isabela — including Volcán Alcedo — carry the lowest visitor quotas in the archipelago. Anyone marketing a “pink iguana” sighting on a standard cruise is overselling; it is not an encounter you can plan for.
Galápagos land iguanas are herbivores, and their diet leans heavily on the Opuntia (prickly-pear) cactus — flowers, pads and fruit alike. Santa Fe shows the relationship well: the island pairs a distinct land iguana with giant Opuntia. On arid islands where standing water is scarce, the moisture and food packed into cactus make it central to the iguana’s survival.
Land iguanas mate from January, and the young hatch around April. That is the species’ breeding biology, not a reason to pick one travel window over another — land iguanas are resident where they live, so you may encounter adults at any time.
Land iguanas show both how fragile island populations are and how they can recover. The Baltra extinction around 1954 came from the same pressures that have hit ground-dwelling reptiles across the archipelago; the population was later re-established from stock elsewhere.
The main threats are invasive species: black rats, feral goats and pigs, cats and dogs, and fire ants. Removing them is the groundwork for any return. Project Isabela cleared goats and pigs from key islands, and rats have been eradicated from sites including North Seymour and Pinzón in 2012. That cleared the way for the 2019 reintroduction on Santiago. It is unglamorous, decade-long work — and the reason land iguanas walk some of these islands at all today.
| Island | Status | Notes | Realistically seen at |
|---|---|---|---|
| Fernandina | Native | Most pristine island; largest, densest iguanas | Punta Espinoza (walk) |
| Isabela | Native | Also the sole home of the separate pink land iguana (Wolf Volcano) | — (pink-iguana range permit-restricted) |
| Santa Cruz | Native | Central island | Cerro Dragón (walk) |
| Santa Fe | Native (endemic form) | Distinct Santa Fe land iguana; giant Opuntia | Santa Fe-Fondeadero (walk) |
| South Plaza | Native | Smallest land iguanas; only place land & marine iguanas interbreed | Plazas Sur (walk) |
| Baltra | Reintroduced | Locally extinct around 1954, later reintroduced | — (airport island; no visitor site) |
| North Seymour | Introduced (from Baltra, 1930s) | Not native | Seymour Norte (walk) |
| Santiago | Reintroduced (2019) | Re-established after invasive-species removal | — |
Several National Park visitor sites let you walk among land iguanas: Seymour Norte on North Seymour, Plazas Sur on South Plaza, Cerro Dragón on Santa Cruz, Punta Espinoza on Fernandina and Santa Fe-Fondeadero on Santa Fe. Which of these you reach comes down to your specific itinerary; several routes cover at least one iguana site.
Wherever you go, the same rules apply. A GNPS-certified naturalist guide is required in protected areas, you must stay at least 2 metres from wildlife, and there is no touching, feeding or flash photography — stay on the marked trails. No operator can promise a specific animal on a given day; wildlife moves on its own schedule.

A large, yellowish, endemic lizard that lives on land and eats mainly plants, especially Opuntia cactus. It is one of four iguana species in the archipelago and lives on several islands — some populations natural, some reintroduced.
The difference is where they feed. The marine iguana is the only lizard that feeds in the sea, grazing on underwater algae. The land iguana stays ashore and eats cactus and other plants. Both are endemic, but they fill completely different niches.
They live on Isabela, Fernandina, Santa Cruz, Baltra, South Plaza and North Seymour. The populations are a mix: some native, Baltra and Santiago reintroduced, and North Seymour’s brought from Baltra in the 1930s.
Not on a normal trip. The pink land iguana — a separate species of about 350 animals, Critically Endangered — lives only on Wolf Volcano, Isabela. That range is permit-restricted and closed to general visitors, so it is not a sighting you can plan for.
They are herbivores whose diet leans heavily on the Opuntia (prickly-pear) cactus — pads, flowers and fruit. On arid islands with little standing water, the moisture and nutrition in cactus make it central to survival. Santa Fe pairs a distinct land iguana with giant Opuntia.
No. They were introduced — brought over from Baltra in the 1930s — so they are not a native population. The island is also known for the largest magnificent-frigatebird colony and prime seabird breeding.
Walking encounters are realistic at Cerro Dragón (Santa Cruz), Plazas Sur (South Plaza), Seymour Norte (North Seymour), Punta Espinoza (Fernandina) and Santa Fe-Fondeadero (Santa Fe). Which you reach depends on your itinerary. A certified guide is required and no sighting is guaranteed.
Baltra’s land iguanas disappeared around 1954, in line with the pressures that have hit ground-dwelling reptiles across the islands, including introduced species. The population was later re-established from stock elsewhere — one of several successful iguana reintroductions in the archipelago.
National Park rules require you to stay at least 2 metres from all wildlife, with no touching, feeding or flash photography, and to keep to marked trails under a GNPS-certified naturalist guide. The iguanas are often unbothered, but the distance rule always applies.
The separate pink land iguana is Critically Endangered, with only about 350 individuals on Wolf Volcano. Land iguanas overall have faced local extinctions and invasive-species pressure, but reintroductions on Baltra, Santiago (2019) and elsewhere have re-established populations.
