Somewhere between booking the flights and packing the bags, almost every guest asks us some version of the same question: can you actually drink the tap water in Costa Rica? It deserves a straight answer, because the real one is more reassuring than most travel guides make it sound.
Yes. In most of Costa Rica you can drink the water straight from the tap. This is one of the few tropical countries where that is the default rather than the exception. And at Kalon the answer is firmer still, because we don’t rely on municipal water at all. We drilled our own well, 200 meters down into the mountain, and we treat what comes up more carefully than many bottled brands treat theirs. More on that below.
Costa Rica’s water is better than you expect
Costa Rica has invested in clean water for decades, and it shows. The large majority of the country receives treated, monitored drinking water, which puts it in a different league from most of the region. In San José, the Central Valley, and the established tourist towns, tap water is simply what people drink. Locals, too. Nobody is boiling anything.
When a guest looks unconvinced, I offer one detail: Costa Rica doesn’t just drink its water, it sells it. RainForest Water, bottled at an artesian source in Sarapiquí, is exported as a premium brand, and Heineken’s Costa Rican arm recently moved to acquire the company. Countries with a water problem don’t produce bottled water a multinational wants to own.
Where you should be more careful
Now the part worth knowing before you land somewhere remote. The general pattern is this: the further you get from the main towns, and often the closer you get to the ocean, the more you should ask before you drink.
Many rural and coastal communities run on small local aqueducts or private wells rather than the national system. Most are fine. Some are inconsistent, especially late in the dry season when sources run low. That is why hotels in remote corners of the country will tell you, sometimes with a small sign in the room, whether their water is drinkable. If there’s no sign and you’re unsure, ask. Nobody here is offended by the question.
And if you have a sensitive stomach, ease in. Costa Rican water is clean, but its mineral profile is different from what your body is used to, and the first days of any trip are when travel catches up with people. That’s not a Costa Rica rule, it’s an everywhere rule.
What about ice, coffee, and brushing your teeth?
These follow the tap. Where the tap water is good, the ice, the coffee, and the toothbrush are good, and in Costa Rica’s tourist areas restaurants overwhelmingly use purified ice anyway. In the remote spots where you’d skip the tap, skip the ice too and use bottled for your toothbrush.
The water at Kalon: our own well, filtered three times
We take water seriously to a degree that surprises people, and honestly, we’re a little proud of it.
Our water doesn’t come from a municipal line. It comes from a private well on the property, drilled 200 meters deep into the ridge, far below anything the surface can touch. From there we filter it, run it through UV treatment, and then filter it again before it reaches a single tap or glass at the resort. Every six months an external company tests it independently. We don’t grade our own homework.
Around the property you’ll find cooled, filtered water stations, sparkling included, because after a morning of surfing you will drink more water than you think, and we’d rather you never have to think about it. Fill your bottle and go.
So, should you drink the tap water?
In most of Costa Rica, yes, and you can stop carrying that quiet worry that tropical travel usually comes with. In the remote corners, ask first. And at Kalon, drink from any tap in the house, because the water in your glass came up from 200 meters down, passed through two filters and a UV treatment on the way, and gets tested, on a schedule, by people we pay to be hard to please.
Hydration matters more here than at home. You’re nine degrees north of the equator, you’re in the ocean every morning, and the sun works fast. The guests who feel best all week are the ones with a water bottle that never leaves their side. We’ll keep it full.
