If you’re heading out on a nature walk in Costa Rica, keep your eyes open; there’s a whole world of lizards waiting to be discovered. Thanks to its wide range of ecosystems, from rainforests and wetlands to dry tropical forests and mountain slopes, Costa Rica is home to some of the most fascinating reptile species in Central America.
Whether you’re a wildlife lover or just curious about the creatures you might come across on the trail, in this blog, we’ll walk you through 11 lizard species you might spot while exploring the great outdoors in Costa Rica.
10 Stunning Costa Rican Lizards You Can Spot at Mistico Park
1. Green Iguana
The green iguana (Iguana iguana) is one of the most recognizable reptiles in Costa Rica. These large lizards can grow up to 6 feet in length, including their tail. They’re usually bright green when young, turning a mix of green, brown, or even orange as they age. You’ll often find them basking in the sun on tree branches or near rivers. Despite their size, they’re herbivores and mostly harmless.
2. Basilisk Lizard (Jesus Christ Lizard)
The Common Basilisk (Basiliscus basiliscus) is sometimes mistaken for its cousin, the plumed basilisk. What makes this species famous is its ability to run on water, earning it the nickname “Jesus Christ Lizard.”
These lizards are usually brown or olive green with faint stripes and a sleek body built for speed. Males may have a small crest on the head or back. You’ll find them near rivers, streams, or ponds, where they quickly dash across the water surface when startled. They’re also excellent climbers and will often dart up trees to escape predators.
3. Whiptail Lizards
Whiptail lizards (Aspidoscelis gularis) are quick, sleek, and always on the move. They have long, slender tails and often feature speckled or striped patterns in shades of brown, green, or blue. You’ll likely find them darting through leaf litter on forest floors, especially in sunny clearings. These lizards are insectivores and very active during the day.
4. Casque-headed Lizards
Casque-headed lizards (Corytophanidae) are known for the helmet-like crest on their heads. These fascinating creatures are masters of camouflage, often staying motionless for long periods to avoid predators. They prefer dense vegetation and are typically found in humid lowland forests. Their unique appearance makes them a favorite among reptile enthusiasts.
5. Plumed (Green) basilisk
The plumed basilisk (Basiliscus plumifrons) is a showstopper with its vivid green body, high crest, and long tail. Males are especially striking, with three prominent crests on the head, back, and tail. These lizards are excellent climbers and swimmers, and they’re often found along riverbanks or resting on branches. They’re shy but active during the day, feeding mostly on insects, small vertebrates, and fruits.
6. Anoles
Compared to other lizards, anoles are small and quick-moving. You’ll often spot them darting through the underbrush, climbing trees, or sunning themselves on leaves. Most are lightweight, with long tails and the ability to change color slightly depending on mood or environment.
Let’s take a look at the different species you might spot on the trails:
Slender anole
The slender anole (Anolis limifrons) lives up to its name; it’s sleek and agile and is often found scurrying through low vegetation. Males have a small, pale throat fan (or dewlap), and both sexes blend in easily with twigs and leaves. You’ll need sharp eyes to catch one, but our guides at Mistico Park will help you!
Green giant canopy anole
As one of the largest anoles, the green anole (Anolis frenatus) is a bright green lizard that lives high in the treetops. It’s harder to spot from the ground, but if you’re lucky, you might see one sunning on a branch. Its bold color makes it a real treat to find.
Pug-nose anole
The Pug-nose anole (Anolis capito) has a distinct short, rounded snout that sets it apart, hence its name. It’s usually seen on tree trunks or in shady areas, often blending in with the bark. Their subtle brown or gray coloring helps them stay hidden from predators.
Stream anole
Stream anoles (Anolis oxylophus) love water and are commonly found near rivers and creeks. They’re fast, with long limbs and tails, and they’re excellent swimmers. If you see one leap into a stream, don’t worry; it’s right at home there!
7. Geckos
Costa Rica is home to several gecko species. One of the most common is the House Gecko (Hemidactylus frenatus), easily recognized by its soft, almost translucent skin and big round eyes. Geckos are mostly nocturnal and are often seen clinging to walls, tree trunks, or even hiding under leaves.
What makes them truly fascinating is their ability to climb vertical surfaces and even walk upside down, thanks to specialized toe pads. Most geckos are insectivores, feeding on moths, ants, and other small bugs, and they’re especially active at night when the forest quiets down.
8. Black Spiny-Tailed Iguana
The Black Spiny-Tailed Iguana (Ctenosaura similis) is one of the largest and fastest lizards in Costa Rica. It gets its name from the prominent, spiny scales running along its back and tail. Adults are typically gray or black, while juveniles may be more colorful with bands or speckles.
You’ll often find them basking on rocks, sunlit branches, or open trails, especially in dry forest areas or sunny clearings. Although they look a bit intimidating, they’re harmless and tend to scurry away when approached. Their diet includes plants, flowers, insects, and small animals, making them quite adaptable.
9. Smooth Helmeted Iguana
The Smooth Helmeted Iguana (Corytophanes cristatus) is a unique and rarely spotted lizard. Its most distinctive feature is the crest or “helmet” on top of its head, giving it a dramatic profile that helps it blend in with bark and leaves.
These iguanas are masters of camouflage, often staying completely still when threatened. Their brown, gray, or olive-toned scales help them disappear into the forest backdrop. They prefer humid, shaded areas and are often seen clinging vertically to tree trunks. Unlike many lizards, they tend to rely on stillness rather than speed as a defense mechanism.
10. Yellow-Spotted Tropical Night Lizard
The Yellow-Spotted Tropical Night Lizard (Lepidophyma flavimaculatum) is a small species. As the name suggests, this lizard is active at night and features yellow or cream-colored spots on a dark background, giving it a speckled appearance. These lizards typically live under leaf litter, logs, or rocks in humid forest areas. They move slowly and feed on insects, spiders, and other small invertebrates.
What is the Best Time to See Lizards in Costa Rica?
You can spot lizards in Costa Rica all year long thanks to the country’s warm tropical climate, but if you’re hoping to catch them at their most active, the green season, which runs from May to November, is a great time to visit. During these months, the rainforest comes alive with moisture, and lizards tend to be more visible as they bask, forage, and move around in search of food.
It’s important to mention that trails are quieter in the mornings and afternoons, regardless of the season; this means you’ll have better chances of spotting lizards, whether they’re darting across a trail or resting in the trees.
