Every English-language account of Costa Rica’s Romería repeats the same figure: two million people walking to a single church. That number comes from the Catholic Church, not from anyone counting. The best independent estimate is closer to 770,000 — still one of the largest annual pilgrimages in the Americas, and still enough to close a national highway.
The basics
What the Romería actually commemorates
On Aug. 2, 1635, a woman named Juana Pereira found a small dark statuette of the Virgin Mary on a rock outside Cartago. Each time she carried it home, the story goes, it returned to the rock. The community read that as instruction and built a shrine on the spot. That shrine became the Basílica de Nuestra Señora de los Ángeles, and the figure — a few inches tall, carved from volcanic stone, graphite and jade — became La Negrita, “the little dark one.”
Costa Rica’s Congress named her patroness of the country in 1824 and reaffirmed it twice, in 1924 and 2002. In 1926 Pope Pius XI granted the image a pontifical coronation, the highest honor the Vatican extends to a Marian image. The walk itself is called the romería, and the people who do it are romeros. Most are not tourists and not, strictly, on vacation. They are paying a promise — asking for something, or thanking her for something already granted.

The walk
Who walks, and from how far
The default route is San José to Cartago: about 25 kilometers east, gaining altitude over the Ochomogo ridge before dropping into the city. Walked steadily it takes six to eight hours, which is why so much of it happens in the dark.
But 25 kilometers is the short version. Groups leave from Zarcero, Naranjo, Guanacaste, Limón and the southern zone days in advance, sleeping along the shoulder. Some walk the final stretch barefoot. Some cover the last meters to the altar on their knees. Traffic police extend their operation to the last weekend of July precisely because so many people start early to avoid the crush.
Wear light or reflective clothing, walk facing traffic, and skip the headphones — these are the specific things Costa Rica’s traffic police ask for every year, because pilgrims are struck by cars every year. Aug. 2 falls in green season. Expect afternoon rain and pack for it.
If you’re driving
What closes, and when
This is the half most visitors need and almost nobody writes down. If you are renting a car and moving around the Central Valley in early August, the Romería will affect you whether or not you have any interest in it.
The knock-on effects reach well beyond Cartago. Officers are posted on Routes 1, 27 and 32, through Heredia, and at fixed control points including the Zapote church, the Garantías Sociales roundabout and San Francisco de Dos Ríos. Cartago’s center takes the tightest restrictions of all.
You cannot fully pre-plan around this. Traffic police decide daily, based on how many walkers actually show up, whether to convert lanes to pedestrian-only or reverse their direction. A route that was open at breakfast may be closed by mid-afternoon. Check the morning you travel, not the week before.
What to do instead
- Don’t drive San José–Cartago on Aug. 1 or 2. Take the train or a bus, or move your plans by a day.
- Heading to the Caribbean or Turrialba? Build in two to three extra hours, or travel before Aug. 1.
- Flying out of SJO on Aug. 2? The airport is west of San José, away from the pilgrimage corridor, but Central Valley traffic is unpredictable. Leave early.
- Already in Cartago? Park outside the restriction ring and walk in. Nothing gets close to the Basílica.
If you want to see it
How to witness the Romería without walking 25 kilometers
You do not have to be Catholic, or Costa Rican, or particularly fit. Standing anywhere along the route on the night of Aug. 1 gives you the essential thing: a national highway full of people walking in the dark, families pushing strollers, vendors selling coffee and tamales from folding tables, Red Cross volunteers taping blisters. Cartago’s municipality sets up rest areas, hundreds of surveillance cameras and drinking-water stations along the corridor.
Ride the bus or train from San José to Cartago on the morning of Aug. 2, after the overnight peak has passed. The Basílica is open, the plaza is full, and you will see the promesas — pilgrims entering on their knees, silver medallions shaped like body parts pinned to the walls in thanks for healings. Buses run frequently and cost around 1,000 colones, roughly $2.
Practical notes
What it means that Aug. 2 is a holiday
Aug. 2 is one of Costa Rica’s twelve official holidays, but it sits in the smaller category of feriado de pago no obligatorio — a holiday employers must grant but are not required to pay. It is also deliberately excluded from the law that shifts some holidays to Mondays for tourism, so it always falls on Aug. 2 regardless of the weekday.
For a traveler, that means banks and government offices close, but plenty of restaurants, shops and tour operators stay open. Nobody can be compelled to work it, so staffing is thin and unpredictable. If a reservation matters, confirm it directly rather than assuming normal hours. For the rest of the year’s calendar, see our month-by-month guide to Costa Rican holidays.
Cartago rewards a longer look once the crowds thin. The city was the colonial capital before San José took the title, and the roofless Santiago Apóstol ruins sit a few blocks from the Basílica. Irazú, one of the country’s most accessible volcanoes, looms directly above town, and Tapantí National Park is a short drive south.
Frequently asked questions
Do two million people really walk the Romería?
Probably not. Two to 2.5 million is the Catholic Church’s estimate, repeated widely in the press. A study by the University of Costa Rica’s statistics school, using household and consumer surveys across three years, put the average closer to 770,000 — around 16% of the population. Either way it is enormous, but the smaller number is the measured one.
Can tourists walk the Romería?
Yes. Nobody checks your faith or your passport, and foreigners walk it every year. Join anywhere along the route rather than starting at the front, walk facing traffic, wear reflective clothing, and treat it as a religious act rather than a spectacle — most people around you are fulfilling a promise.
Which roads close for the Romería?
The core closure is about four kilometers of Ruta 2 between the Fuente de la Hispanidad and la antigua Galera, plus roughly three blocks around the Basílica in Cartago, starting Aug. 1. Routes 1, 27 and 32 and the Florencio del Castillo see heavy enforcement and possible lane changes. Decisions are made day by day based on crowd size.
Is Aug. 2 a public holiday in Costa Rica?
Yes, but it is a feriado de pago no obligatorio — granted, not necessarily paid. Banks and public offices close. Many private businesses stay open with reduced staff. Unlike some Costa Rican holidays, it is never moved to a Monday.
How far is the walk from San José to Cartago?
About 25 kilometers, or 15 miles, climbing over the Ochomogo ridge. Six to eight hours at a steady pace. Pilgrims from Guanacaste, Limón and the southern zone walk considerably farther, setting out days ahead.
Before you go
Closure details shift year to year with road construction and crowd size. Costa Rica’s transport ministry and traffic police publish the operational plan in mid-July — check it before you travel, not from memory.
