Ensuring Safe Hydration: American Tourists and Drinking Water Safety in Cabo San Lucas


Cabo San Lucas, with its picturesque beaches, vibrant nightlife, and stunning natural beauty, has long been a favored destination for American tourists seeking an idyllic getaway. As visitors immerse themselves in the local culture and embrace the sunny paradise, it's crucial to prioritize their health and safety. One essential aspect is ensuring access to clean and safe drinking water. In this blog post, we will explore the topic of drinking water safety in Cabo San Lucas, providing insights and tips to help American tourists make informed choices during their stay.

Understanding the Water Situation

Cabo San Lucas, like many other tourist destinations, faces challenges in maintaining water quality and safety. The local water supply primarily comes from desalination plants and wells, with varying levels of treatment. While the municipal water supply undergoes treatment processes, the distribution system and infrastructure can still be susceptible to contaminants, especially those that affect foreign visitors who aren’t used to the local water composition.

Water Quality

In general, it is advisable for American tourists to exercise caution when consuming tap water or using it for brushing teeth or cleaning food. The main concern lies in the potential presence of bacteria, parasites, or other impurities that may cause gastrointestinal issues. These contaminants can affect individuals who are not accustomed to the local water and its unique composition.

Safe Drinking Water Practices

To ensure a safe and enjoyable trip to Cabo, it is recommended that American tourists follow these guidelines when it comes to water usage:

  1. Location: Realize that the places you visit will differ regarding water quality. Many of the larger resorts and tourist restaurants have robust filtration systems for their guests to help avoid their visitors from getting sick. Some Airbnbs and other rentals may also have filtration systems installed by the owners. Be sure to always ask. Even with filtration, the risk of having an issue can still be present. Never drink “agua de casa” or house water at restaurants. Always opt for bottled water if you’re unsure or if you know your body is sensitive. All of EDS Destination rentals have filtered water and also provide a supply bottled water for our guests for their convenience.

  2. Bottled Water: The most reliable option is to rely on commercially bottled water, which is widely available at hotels, restaurants, and convenience stores. Look for reputable brands and ensure that the bottle seal is intact before consumption. EDS Destinations provides complimentary bottled water depending on the length of stay for all of our non-timeshare luxury rentals.

  3. Boiled or Filtered Water: If you absolutely must use tap water as your only option (we don’t recommend it), boil it for at least two minutes to kill bacteria and parasites. Alternatively, consider using water filters or water purification tablets designed to eliminate impurities.

  4. Ice and Beverages: When ordering beverages, particularly those with ice, ensure that they are made with purified water or bottled water. Many restaurants purchase filtered ice, but you can alway ask to be sure. Avoid using tap water to make ice at a vacation rental or in your hotel room. Again, many larger resorts and hotels will have filtered ice, but always check first.

  5. Brushing Teeth: Use bottled water or water that has been boiled and cooled for brushing your teeth. This practice minimizes the risk of ingesting harmful microorganisms. Never swallow the tap water.

  6. Food Preparation: While dining out, choose reputable restaurants that adhere to proper hygiene standards. Fruits and vegetables should be washed thoroughly with purified water or peeled to minimize any potential contaminants. Some tourists avoid produce that cannot be peeled, such as tomatoes, altogether.

  7. Be Prepared: Before you travel, there are some steps you can take to prepare your body for the unfamiliar things you may encounter in Mexico. It may be a good idea to take high quality pre and probiotics starting several weeks before your trip to boost your gut health. Some people take the vaccine Dukoral before traveling to prevent potential exposure to E-coli contamination from food or water. It’s also popular to bring or buy antihistamines, anti-diarrheals, immodium, and Pepto Bismol chewables along just in case. If you do become sick while in Cabo, there are many local pharmacies around that can give you stronger medication like Vermox for parasite infection or other issues related to the water. Be safe and avoid these issues by exercising lots of caution!

Drinking water safety is an important consideration for American tourists visiting Cabo San Lucas. While the local authorities make efforts to maintain water quality, it's prudent to take precautions to avoid any health-related issues during your stay. By following these simple guidelines, such as opting for bottled water, boiling tap water, and being mindful of food preparation practices, tourists can ensure their hydration needs are met while minimizing potential risks. Ultimately, prioritizing personal health and safety allows visitors to fully embrace the charm and beauty of Cabo San Lucas, creating cherished memories that will last a lifetime.
