One of the most common questions travelers ask when planning a trip abroad is a simple but important one: “Is the water safe to drink?” If you are traveling to Costa Rica for a few weeks of vacation, this question naturally comes up—especially if you plan to explore different regions of the country, from cities and beach towns to remote rainforests and rural villages.
So, is the water safe to drink in Costa Rica?
The honest answer is: there is no simple yes or no. It depends very much on where you are, what your body is accustomed to, and how cautious you want to be while traveling. Let’s take a closer look at Costa Rica’s water quality, regional differences, traveler experiences, and the safest choices you can make during your visit.
Costa Rica’s Water: An Abundant Natural Resource
Costa Rica is blessed with an extraordinary abundance of fresh water. Thanks to its steep mountain ranges, frequent rainfall, and extensive protected forests, the country has countless rivers, springs, and underground aquifers. Much of the drinking water originates from deep mountain reserves, where rainwater is naturally filtered through volcanic rock and soil before reaching springs and municipal systems.
Because of this, Costa Rica does not suffer from water scarcity, unlike many other countries in the region. In fact, overall water quality in Costa Rica is considered very good by Central American standards, and in many places it rivals water quality in North America and Europe.
Is Tap Water Safe to Drink in Costa Rica?
The Short Answer
In many parts of Costa Rica, yes—the tap water is safe to drink. However, not everywhere, and not for everyone.
Urban Areas and the Central Valley
In major cities and towns such as:
- San José
- Alajuela
- Heredia
- Cartago
the municipal water systems are well maintained, regulated, and treated. Locals drink tap water daily without concern, and visitors often do as well without any issues.
In these areas, the water is generally considered potable (safe for drinking).
Why Some Travelers Still Get Sick
Despite the generally good quality of Costa Rica’s water, some travelers experience stomach cramps, bloating, or diarrhea after drinking tap water—even in areas where locals have no problems at all.
This does not necessarily mean the water is contaminated.
In many cases, the issue is simply a change in water composition. Different mineral content, bacteria levels (even harmless ones), and unfamiliar microorganisms can upset a visitor’s digestive system, especially if they have a sensitive stomach.
As someone who has led many tour groups to Costa Rica, I have seen this happen occasionally. It is not common, but it does occur. Even travelers who are careful and healthy may react unexpectedly.
Rural Areas and Remote Locations
When you move outside of major cities, the situation changes.
In:
- Small rural villages
- Remote beach towns
- Mountain lodges
- Rainforest areas
water systems may be:
- Less regulated
- Sourced from local springs
- Maintained by small communities
While many of these water sources are clean and natural, they may not be consistently treated or tested, especially after heavy rains, which can introduce sediment or bacteria into the system.
In these areas, drinking tap water is not always recommended for travelers.
Hotels, Eco-Lodges, and Resorts
Most hotels and eco-lodges in Costa Rica are very aware of travelers’ concerns about water. Many will:
- Clearly state whether their tap water is safe to drink
- Provide filtered water stations
- Offer complimentary bottled water
Higher-end resorts often use advanced filtration systems, making their tap water perfectly safe for guests. Still, it is always wise to ask at the front desk if you are unsure.
Bottled Water: The Safest Choice for Travelers
To avoid any possible digestive problems, many travelers choose the safest and simplest option: drink bottled water.
Availability
Bottled water is available everywhere in Costa Rica, including:
- Supermarkets
- Small convenience stores
- Gas stations
- Hotels
- Restaurants
You will never have difficulty finding it, even in small towns.
Important Tip
Always check the seal on bottled water to make sure it has not been opened or tampered with. This is a good habit anywhere in the world.
What About Ice in Drinks?
In restaurants, especially those catering to tourists, ice is typically made from purified water and is generally safe. However, in very small local eateries or rural areas, ice may be made from tap water.
If you want to be extra cautious:
- Ask if the ice is made from purified water
- Or simply order drinks without ice
Brushing Teeth and Showering
Many travelers wonder if they need to use bottled water for brushing their teeth.
In most parts of Costa Rica:
- Brushing teeth with tap water is fine
- Showering is completely safe
Even travelers who choose bottled water for drinking usually have no problems using tap water for daily hygiene.
A Common Home Remedy for Travelers
One practical tip that experienced travelers often use is a simple preventive measure:
Take one Pepto-Bismol tablet each morning.
This can help:
- Soothe the stomach lining
- Reduce the risk of digestive upset
- Minimize mild diarrhea caused by unfamiliar foods or water
Of course, this is not medical advice, but many travelers find it helpful, especially during the first few days of their trip.
Other Ways to Protect Your Stomach
Water is not the only factor that can cause stomach issues while traveling. Keep these tips in mind:
- Wash your hands frequently or use hand sanitizer
- Avoid unwashed fruits and vegetables unless peeled
- Eat at restaurants with good hygiene and steady customer traffic
- Avoid food that has been sitting out for long periods
Costa Rican food is generally fresh and safe, but your digestive system may still need time to adjust.
Environmental Considerations
Costa Rica is a global leader in sustainability and environmental protection, and plastic waste is an increasing concern.
If you want to reduce plastic use:
- Bring a reusable water bottle
- Use refill stations at hotels and lodges
- Use a portable water filter or purification system
This allows you to stay healthy while being environmentally responsible.
Final Verdict: Should You Drink the Water in Costa Rica?
So, is it safe to drink the water in Costa Rica?
Yes—in many places.
But not everywhere.
And not for every traveler.
If you are staying in major cities or reputable hotels, tap water is generally safe. However, to avoid even the slightest chance of stomach problems, especially on a short vacation, bottled water is the safest and easiest option.
Costa Rica has excellent water resources, and most locals drink tap water daily without issue. As a visitor, your body simply may not be used to the change—and there is no reason to risk discomfort when bottled water is so readily available.
In Summary
- Costa Rica has abundant, high-quality water
- Tap water is safe in many urban areas
- Some travelers experience stomach issues due to water changes
- Bottled water is widely available and recommended
- Simple precautions can ensure a healthy, enjoyable trip
With a little awareness and preparation, you can relax and enjoy everything Costa Rica has to offer—lush rainforests, beautiful beaches, warm people, and unforgettable experiences—without worrying about what’s in your glass.
