Tips:

• Women should always avoid walking alone on deserted sections (unpatrolled) of beach. No matter the level of safety in Punta Cana, err on the side of caution.
• Only bring the amount of money that you need when going shopping
• If you’re going somewhere at night – traveling in groups or with a guide is recommended.
• Salespeople can be very aggressive, don’t be rude to them! The best way to avoid looking at their goods is to tell them you didn’t bring any money and promise to go back later.
• Leave all your valuables in the safety deposit box in your room – not on the beach while you’re swimming.
• Teach your family about how to get out of a riptide – they probably won’t ever need it but it could save their life.
• Wear water shoes if swimming out to the reef.
• Taxis or tour buses are the safest way to get around; “gua-guas” the local buses are a great way to check out local culture but are not quite as safe (seasoned travelers only)
