The Dominican Republic is one of the Caribbean’s most beloved destinations, with postcard-perfect beaches, vibrant music, and welcoming locals. But just because it’s a popular tourist spot doesn’t mean you should treat it like any other resort getaway. Cultural missteps, safety oversights, and social faux pas can quickly turn your dream vacation into a stressful ordeal.
Many travelers come to the Dominican Republic with good intentions but bring with them habits and assumptions that don’t translate well. From ignoring local greetings to flaunting flashy jewelry, tourists often make the same avoidable mistakes—many of which frustrate locals or invite unnecessary risk. What seems normal at home might come off as disrespectful or even dangerous here.
To enjoy the Dominican Republic the right way, it’s important to understand not just what to do—but what not to do. These 20 tips aren’t about scaring you; they’re about helping you travel smarter, deeper, and more respectfully. You’ll have a richer, safer experience by knowing what locals wish tourists would stop doing.

Quick Easy Tips
Don’t drink tap water—stick to bottled water.
Avoid flashy clothes or jewelry—it attracts pickpockets.
Respect beach flags and warning signs—some waters are deceptively rough.
Always greet people with a polite “buenos días” or “buenas tardes.”
Don’t assume everyone speaks English—basic Spanish goes a long way.
Be cautious using your phone in public in urban areas.
One major point of tension is the “resort bubble” mentality. Many travelers never leave the all-inclusive zone and treat the Dominican Republic like a theme park. While resorts provide comfort, they often isolate visitors from the real culture, economy, and people. Locals see this disconnect as disrespectful—especially when tourists act entitled or unaware of the country’s daily realities.
Another friction point is how tourists treat local customs around gender and personal space. Dominican culture can be flirtatious and expressive, which might confuse outsiders. But responding with rudeness, over-friendliness, or hyper-defensiveness can be misinterpreted. Learning the difference between politeness and genuine interest is key to avoiding awkward situations.
There’s also growing frustration with travelers who behave like everything is negotiable—whether it’s haggling too aggressively with vendors or ignoring environmental rules. This “bargain hunter” mindset may seem savvy, but to locals, it can signal disrespect or exploitation. The cost of living here is not a game, and your dollars go further when they’re spent thoughtfully.
Things Not to Do in Dominican Republic
1. Don’t Drink Tap Water
Tap water in the Dominican Republic is not safe for drinking. Always drink bottled or purified water and avoid ice unless you’re certain it’s made with purified water.
2. Don’t Forget to Negotiate Prices
Haggling is common in local markets and with street vendors. Don’t accept the first price offered; polite bargaining is expected.
3. Don’t Ignore Currency Exchange Rates
The Dominican peso (DOP) is the official currency. Avoid using US dollars for all transactions, as this often results in unfavorable exchange rates.
4. Don’t Walk Around at Night Alone
While most tourist areas are safe, walking alone at night, especially in non-touristy or isolated areas, can make you a target for petty crimes.
5. Don’t Assume Everyone Speaks English
Spanish is the official language, and while many people in tourist areas speak some English, learning a few basic Spanish phrases will go a long way.
6. Don’t Forget to Tip
Tipping is customary in the Dominican Republic. While some restaurants include a 10% service charge, it’s polite to leave an additional 5-10% for good service.
7. Don’t Overlook Traffic Rules
Traffic can be chaotic, and road rules are often loosely followed. Be cautious when driving or crossing streets.
8. Don’t Rely on Credit Cards Everywhere
While credit cards are accepted in many places, smaller vendors and local establishments often prefer cash. Always carry some pesos with you.
9. Don’t Swim Where It’s Prohibited
Some beaches have strong currents or hidden dangers. Always swim in designated areas and heed local warnings.
10. Don’t Forget Sunscreen
The Caribbean sun is intense, so don’t skimp on sunscreen. Avoid getting sunburned, especially early in your trip.
11. Don’t Assume All Beaches Are Public
Many resorts have private beaches, and access may be restricted to guests. Check before venturing onto a seemingly secluded beach.
12. Don’t Ignore Safety Warnings About Food
Stick to cooked foods and fruits that can be peeled. Be cautious about eating from street vendors, as food hygiene can vary.
13. Don’t Expect Punctuality
The concept of time in the Dominican Republic is relaxed. Be patient and embrace the slower pace of life.
14. Don’t Forget Bug Spray
Mosquitoes can be a nuisance, and there’s a risk of mosquito-borne diseases like dengue. Always carry bug spray.
15. Don’t Be Flashy with Valuables
Avoid wearing flashy jewelry or showing off expensive gadgets in public. This can attract unwanted attention.
16. Don’t Expect Resort-Level Cleanliness Everywhere
While resorts are often immaculate, standards in public spaces, markets, and some smaller establishments might be different. Adjust your expectations accordingly.
17. Don’t Be Afraid to Try Local Food
While you should be cautious about hygiene, don’t shy away from trying local dishes like mangú, sancocho, or fresh seafood.
18. Don’t Forget Travel Insurance
Healthcare can be expensive for tourists, and unexpected issues like injuries or illnesses can arise. Travel insurance is a must.
19. Don’t Disrespect Local Culture
The Dominican Republic is deeply religious, predominantly Catholic, and conservative in some areas. Dress modestly when visiting churches and respect cultural norms.
20. Don’t Assume Every Vendor’s Offer is Genuine
Some vendors may try to sell fake goods or overcharge tourists. Use caution when buying souvenirs or services and ask locals for trusted recommendations.
Final Thoughts
The Dominican Republic is an incredibly rewarding place to visit—but only if you leave behind the tourist playbook and embrace the local rhythm. Small actions—like dressing modestly in town, learning a few phrases in Spanish, or understanding tipping etiquette—show that you care about the culture you’re stepping into.
No destination owes you a “perfect” trip. The most memorable experiences come not from sticking to your comfort zone but from being open, curious, and considerate. Dominicans are known for their warmth and humor, and if you approach them with humility, you’ll be welcomed with genuine kindness.
So before you pack your beach towel and sunscreen, remember: how you act matters more than where you stay. Respect goes a long way, and by avoiding these 20 common mistakes, you’ll not only stand out as a smarter traveler—you’ll leave with stories that last long after the tan fades.
