How Does Water Safety Work in Costa Rica?
Last verified: 2025-06 · Americas
1The Quick Answer
Tap water is safe to drink in San José and most developed areas, making Costa Rica one of the few Central American countries where this is reliable.
2What You Need to Know
San José and most urban and developed tourist areas have treated municipal water that meets WHO drinking standards — you can drink from the tap at hotels and restaurants without concern. In rural areas, remote villages, and some beach towns, water quality can vary and locally sourced water may not be treated; check with accommodation staff before drinking. The Caribbean coast and some isolated Pacific communities are more likely to have water quality concerns than the Central Valley and Pacific resort areas. Bottled water is inexpensive and widely available everywhere if you prefer certainty.
3Practical Tips
Practical Tips
- 1Ask your hotel or guesthouse host about local tap water quality — they will give you honest advice.
- 2In national parks and on multi-day hikes, carry a water filter or purification tablets as river water is not safe to drink.
- 3Bottled water at supermarkets is very cheap — buying a large 5-litre bottle at a supermarket is far more economical than buying small bottles daily.
