The Central American squirrel monkey is the one animal in Manuel Antonio National Park you cannot see anywhere else on earth, and the first two hours after the 7:00 a.m. gate opening are when you are most likely to find a troop. Saimiri oerstedii citrinellus is endemic to a narrow strip of the Central Pacific coast around Quepos and Manuel Antonio, the IUCN lists the species as endangered, and it is the reason a lot of wildlife travellers choose this park over larger ones. This page is what our guides actually know about finding it: the hour, the trail, the season, what the spotting scope changes, and the four honest ways to book a walk that is built around it.
It is Saimiri oerstedii citrinellus, the Central Pacific subspecies of the Central American squirrel monkey, and its entire world range is the coastal strip that includes Quepos and Manuel Antonio. That is the whole point: the howler, the capuchin and both sloths in this park live across large parts of Central America, but this monkey does not. The IUCN lists the Central American squirrel monkey as endangered, and habitat loss along a developed tourist coast is exactly the pressure involved. Locally everyone calls it mono tití, and if a guide says “tití” on the trail, this is the animal.
Physically it is small — an adult body fits comfortably in two hands, with the tail longer than the body — with an orange-gold back, cream chest, a pale face and a dark cap on the crown. That cap is the field mark that settles every argument: capuchins have a white face and a black cap that is part of a much larger, heavier animal, and a squirrel monkey is roughly a third of the size and never still.
Between 7:00 and 9:00 a.m., and it is not a close call. Squirrel monkey troops move most at first light, feeding through the lower and middle canopy in a loose, fast-travelling group, and a troop crossing overhead is loud enough in the leaves that you hear it before you see it. By late morning the heat has pushed activity down and the park is at its busiest, which works against you twice over.
They travel in troops that can run to twenty, thirty or more animals, and that is the good news for a visitor: this is not a single hidden animal like a sloth, it is a moving event. Either the troop is in your section of forest or it is not. A 7:00 a.m. start is the single decision that most changes your odds, and it is why every option we run meets at the park opening rather than mid-morning.
The lower and middle canopy along the flat entrance trails, and the secondary growth where the forest meets the beaches — not the tall closed canopy and not the viewpoints. Squirrel monkeys are insect and fruit eaters working the outer branches and tangles, so the productive habitat is the messy edge, not the cathedral forest. Our guides find them most often along the Sendero Perezoso boardwalk and the first section of the Punta Catedral loop, and in the treeline behind the beaches inside the park.
Outside the park they also move through the gardens and roadside trees of the Manuel Antonio road and some hotel grounds, which is why guests sometimes see a troop from a balcony and then miss them inside the park. Both are the same population; the difference is that inside the park nobody is feeding them.
The dry season from December to April makes them easier to see rather than more numerous. Fewer leaves and better light mean a small fast animal at canopy height stops being a silhouette, and the mornings are more reliably clear at 7:00 a.m. The troops are resident year round and do not leave in the green season — in September and October you are dealing with wetter light and a higher chance of rain later in the day, not an absent animal.
The month matters more for the crowd than for the monkey. December and January bring the year’s heaviest visitation against a 2,500-visitor daily cap, so a 7:00 a.m. slot in high season is worth more than the same slot in May.
Three things, and each one costs sightings. First, people expect the animal they saw on a hotel balcony: habituated monkeys that come close. Inside the park the troops are wild, they are twelve to twenty metres up, and they do not approach — which is the correct outcome, not a disappointment. Second, people confuse them with capuchins and then report having seen both when they saw one. Third, and most damaging, visitors feed them, or accept a photo opportunity created by feeding. Human food and hand contact spread disease through a troop, change foraging behaviour and, for an endangered endemic on a developed coast, are a genuine conservation problem. Never feed them, keep food closed in a bag, and do not touch.
One more practical mistake: standing still for too long in one spot. Squirrel monkeys travel. If a troop has passed through, the productive move is to walk quietly to the next block of edge habitat, not to wait where they used to be.
The Sendero Perezoso boardwalk and the first section of the Punta Catedral loop, because both run through the low secondary canopy and forest edge where squirrel monkey troops feed.
Manuel Antonio has four trails inside the park and they are not interchangeable for wildlife:
The park is open 7:00 a.m. to 3:00 p.m., Wednesday to Monday, and closed every Tuesday. Entry is capped at 2,500 visitors a day, so on a December morning the 7:00 a.m. slot is both the quietest trail and the most active hour of animal movement — the same decision solves both problems.
It turns a gold smudge moving through leaves twelve to twenty metres up into an animal with a pale face, a dark cap and something in its hands. A squirrel monkey is small and fast, and at canopy height with the naked eye it is movement, not an animal — which is why visitors walk past a feeding troop and only register the noise.
It also solves a problem the naked eye cannot: everyone in the group sees the same animal. Without a scope, a guide points at a canopy fork and half the group never finds it before the troop moves on. With the scope on a tripod, each person steps up and looks at the same frame, and it takes phone photos through the eyepiece that are worth keeping. The scope is included on every option, from the $30 Classic up — it is not a premium add-on.
Four options cover the same park and the same trails at $30, $65, $69 and $100 per person; what changes is group size, transport and whether we handle your park ticket. Prices are per person: adults 13 and over pay the listed price and children 3 to 12 pay $10 less on every option — Classic $20, Premium $55, Classic Private $59, VIP Private $90 — and children under 3 go free.
If you buy the SINAC entrance yourself it costs $18.08 for a non-resident adult and $5.65 for a child, checked against SINAC’s official park page on 25 September 2026. Parking near the entrance runs roughly $4 to $10 for the day at a legal lot with a real attendant.

We will not promise you a squirrel monkey, and nobody honest will. We are a local company guiding inside Manuel Antonio National Park with certified naturalist guides, a 4.9 rating from 257 reviews, and free 4K photos and video sent after every tour. What we control is the hour we start, the trail we choose, the guide who walks those same trees every morning and the scope that turns a movement in the leaves into an animal.
Tell us your date, your hotel and how many you are. Message us on WhatsApp and we answer 24/7, or check availability and book the tour online. If you are travelling in December or January, book early: the park caps entry and the SINAC ticket window only opens two months ahead.
Yes. Manuel Antonio National Park is one of the few places on earth where the Central American squirrel monkey lives, and the Central Pacific subspecies Saimiri oerstedii citrinellus is found only along this coast around Quepos and Manuel Antonio.
Mono tití. If a Costa Rican guide says tití on the trail, they mean the squirrel monkey, not the capuchin, which is mono cara blanca.
No, and no honest guide or website will promise one. A troop is either moving through your section of forest that morning or it is not. What raises the odds is the 7:00 a.m. start, the right trail and a guide who walks those trees every day.
The first two hours after the park opens at 7:00 a.m. Troops feed and travel most at first light, and activity drops as the heat builds toward midday.
Size and face. A squirrel monkey is small and gold-orange with a pale face and a dark cap, and it never stops moving. A white-faced capuchin is roughly three times the body mass, black-bodied with a white face and shoulders, and moves deliberately.
The IUCN lists the Central American squirrel monkey as endangered. The Central Pacific subspecies here has a very small total range along a heavily developed tourist coast, which is the core of the problem.
You can enter the park without one, but a canopy-height animal the size of a housecat is what guides and spotting scopes exist for. Our guides walk the same trees every morning and know where the troop fed yesterday.
From $30 per person for the Classic small-group walk, $65 for Premium with hotel transport and your park ticket handled, $69 for a Classic Private tour and $100 for VIP Private with private transport and lunch. Children 3 to 12 pay $10 less on every option.
