Costa Rica covers less than 0.03 percent of the earth’s surface. The animals of Costa Rica are not confined to reserves. They share the landscape with every visitor who arrives, in the garden, above the pool, on the beach at dawn. It holds approximately five percent of the world’s biodiversity. Those two numbers, placed next to each other, begin to explain what visitors experience when they arrive: wildlife that appears without effort, in concentrations that most countries simply cannot offer.
Scarlet macaws crossing the canopy in pairs at dawn. A sloth suspended in a cecropia tree above the pool deck. Howler monkeys announcing the morning from a ridge above the beach. A humpback whale breaching in the bay below the villa terrace. These are not managed encounters in a reserve. They are the ordinary texture of a morning in Costa Rica when you are in the right place.
This guide covers the wildlife worth knowing about before you arrive, where to find it across the Pacific coast, and how the right villa position changes what you see and how close you get to it.
The biological richness of Costa Rica is not accidental. It is the result of geography, climate, and fifty years of conservation policy working together in an unusually productive combination.
The country sits at the junction of North and South America, functioning as a biological corridor between the two continents for millions of years. Species from both landmasses have mixed here, producing an exceptional diversity that neither continent holds in isolation. The varied topography, from sea-level Pacific coast to cloud forest highlands to Caribbean lowlands, creates dozens of distinct ecosystems within a small territory.
More than 25 percent of the country is protected as national park or biological reserve, a higher proportion than almost any other nation. That commitment, maintained consistently since the 1970s, has allowed forests to recover and wildlife populations to stabilize in ways that are visible on the ground. The deforestation that stripped the country of much of its tree cover by the 1980s has been reversed: forest cover has grown from 21 percent in 1987 to over 52 percent today.
The result is a country where wildlife encounters are not exceptional. They are simply what happens when you go outside.
The scarlet macaw is Costa Rica’s most visually striking resident, and the Pacific coast is one of the best places in the world to see them. The birds are large, impossibly colored, and almost always travel in bonded pairs. Seeing them cross a clearing or settle in a tree above the surf is one of those sights that does not diminish with repetition.
The Central Pacific coast around Manuel Antonio and Quepos has one of the highest concentrations of scarlet macaws in the country. The South Pacific zone, from Dominical south, also supports strong populations. On the Nicoya Peninsula, sightings are less consistent but occur regularly in the forested areas around Nosara and the hillsides above Santa Teresa.
The howler monkey announces itself before it is seen. The call, which carries several kilometers at dawn and dusk, is one of the defining sounds of Costa Rica and one of the more disorienting experiences for guests who encounter it for the first time without warning. The animal responsible is considerably smaller than the sound suggests: a medium-sized, dark-furred monkey that moves slowly through the canopy and spends much of the day resting.
Howler monkeys are present across most of the Pacific coast wherever forest cover is sufficient. Properties surrounded by mature trees, hillside villas above established jungle, and estates with large gardens tend to have resident troops that become familiar presences over the course of a stay.
Costa Rica has two sloth species: the three-toed sloth and the two-toed sloth. Both are present across the Pacific coast, though sightings require more patience than with macaws or monkeys. Sloths move slowly, blend with the branches they inhabit, and spend most of their lives in the middle canopy rather than at eye level.
The Caribbean coast, including the area around Cahuita and Puerto Viejo, has the highest sloth density in the country. On the Pacific side, the South Pacific zone and the gardens of well-vegetated villa properties produce the most consistent sightings. Keep It Green House on the Caribbean coast, with its dense tropical gardens, has sloths in residence regularly.
Costa Rica is one of the most significant sea turtle nesting destinations in the world. Four species nest on its beaches: leatherback, green, hawksbill, and olive ridley. The Pacific coast receives all four.
Olive ridley turtles arrive in mass nesting events called arribadas on the beaches of Guanacaste, particularly at Playa Ostional near Nosara, from July through November. The arrivals are one of the most extraordinary wildlife spectacles in the world: thousands of turtles coming ashore simultaneously to nest on the same beach over the course of several days. Local guides manage access carefully, and the experience is available to visitors who arrange it in advance.
Leatherback and green turtles nest on quieter Pacific beaches through the same period. The South Pacific coast, around Marino Ballena and down toward the Osa, has active nesting beaches. The Caribbean coast receives green turtles in significant numbers at Tortuguero, one of the most important green turtle nesting sites in the world.
Covered in depth in the Maison R&V whale watching guide, but worth noting here in the context of wildlife more broadly: Costa Rica is one of the only places on earth where two separate humpback whale populations converge on the same protected marine area. The southern hemisphere migration peaks between August and October. The northern hemisphere migration follows from December through April.

The South Pacific coast, particularly around Marino Ballena National Park near Uvita, offers the most reliable sightings. Properties with ocean views above this zone, including Casa La Vista and Casa Colibri near Uvita, allow guests to watch the bay from the terrace before joining a morning tour.
Pantropical spotted dolphins and bottlenose dolphins are present year-round in Costa Rica’s Pacific waters and are reliably encountered on any marine tour. They are less the subject of a dedicated excursion and more a consistent presence on the water, appearing alongside whale watching tours, fishing trips, and snorkeling excursions without particular arrangement.
The Caribbean coast holds the densest populations of poison dart frogs in Costa Rica. The blue-jeans frog, named for its vivid red body and blue legs, is the most commonly seen species and is abundant in the gardens and forest edges around Cahuita and Puerto Viejo. The frogs are small enough to miss if you are not looking, and unmissable once you have learned to look.
The quetzal is Costa Rica’s most celebrated bird and one of the most sought-after wildlife sightings in the Americas. It inhabits cloud forest at elevation, with the best viewing opportunities in the Monteverde and San Gerardo de Dota zones in the central highlands. It does not occur on the Pacific coast at low elevation. For villa guests whose itinerary includes a highland excursion, the quetzal is worth planning around specifically during the March and April nesting season.
Costa Rica is home to more than 900 bird species, making it one of the premier birdwatching destinations in the world. The Pacific coast alone supports toucans, trogons, kingfishers, herons, frigatebirds, and dozens of tanager and hummingbird species visible without leaving the villa grounds.
The most significant variable in wildlife encounters on a Costa Rica villa stay is not which national park you visit. It is where the property sits within its own landscape.
A villa surrounded by mature trees on a hillside above the coast will have resident howler monkey troops, regular macaw overflights, and the particular quality of mornings in which the wildlife is already present before the day begins. A property in a more developed area, with manicured gardens and close neighbors, will see less.
The South Pacific zone around Dominical and Uvita, where forest cover in the hills above the coast is among the densest on the Pacific, produces the most consistent villa-level wildlife encounters. Properties like Villa Birdsong Vista, set within seven acres of private jungle above Dominical, offer a wildlife experience that requires no excursion planning at all: the birds, the monkeys, and the insects that define the Costa Rican soundscape are present on the grounds.
Villa Mariposa Azul in Mal País, on 2.2 secluded hectares with a hiking trail through the property, brings guests into daily contact with the flora and fauna of the Nicoya Peninsula in a way that a beach-facing property cannot. The trail, the waterfall in wet season, and the surrounding vegetation create a private nature experience that supplements rather than substitutes for the wider landscape.
Maison R&V’s concierge team can coordinate naturalist guides, wildlife photography specialists, and specialist excursions including night walks, bird walks, and marine tours for guests whose interest goes beyond what the villa grounds provide.

Manuel Antonio National Park is the most visited in Costa Rica and for good reason. Small, accessible, and extraordinarily productive for wildlife viewing, the park combines several beach environments with primary forest and supports white-faced capuchin monkeys, three-toed sloths, agoutis, and dozens of bird species within a short walking trail network. For guests staying in the Central Pacific zone, a morning in Manuel Antonio produces more wildlife sightings per hour than almost any other experience in the country.
Marino Ballena National Park near Uvita protects the marine area and coastline that includes the Whale’s Tail sandbar and the convergence zone for both humpback whale migrations. The park is compact and accessible, with minimal infrastructure and a genuinely wild character. For guests in the South Pacific, it is the natural anchor of the wildlife week.
Corcovado National Park on the Osa Peninsula is the most biodiverse lowland rainforest in Central America and one of the last places on the Pacific coast where jaguars, tapirs, and all four species of Costa Rican monkeys can be seen in the same area. It requires more planning than Manuel Antonio, typically accessed by boat from Drake Bay or by a guided hike from Los Patos, but the experience it delivers has no equivalent on the Pacific coast.
Monteverde Cloud Forest Reserve suits guests whose itinerary includes a highland section. The cloud forest at Monteverde is one of the most productive birdwatching environments in the Americas, with the quetzal, numerous hummingbird species, and the otherworldly atmosphere of a forest perpetually wrapped in mist.
Wildlife encounters in Costa Rica are most productive in the early morning and late afternoon. The heat of midday moves animals into shade and stillness. The two hours after dawn and the hour before sunset produce the highest activity across species.
A local guide changes what is visible. The difference between walking a forest trail alone and walking it with an experienced naturalist is the difference between seeing ten species and identifying forty. For guests whose stay includes a serious wildlife day, a guide is worth arranging specifically rather than relying on self-guided exploration.
Binoculars improve almost every encounter. The macaws that cross overhead, the sloth that is audible but not yet located, the tanager in the canopy edge, all are significantly better with optics. A compact pair takes minimal luggage space and transforms the passive observation that happens from a villa terrace into something considerably more engaging.
