When flying in to the Dominican Republic, Las Américas International Airport (SDQ) is your best choice, only a short drive from downtown Santo Domingo.
Although US dollars are widely accepted, especially in tourist areas, the Dominican Peso (DOP) is the official currency of the Dominican Republic. ATMs are common, but it's always good to carry a little cash, as some vendors do not accept electronic purchases. Currency exchange services are readily available at airports, hotels and exchange offices. While ApplePay is still relatively new and not always available. For Australians, we've used online banking services like UpBank in the past where no additional fees were charged and contactless payments via their mobile app worked seamlessly.
Using an eSIM is the easiest way to stay connected in the Dominican Republic. Most newer iPhone, Samsung, Pixel, and other devices also support eSIM. You can purchase an eSIM online and set it up on your device before you arrive, so it's ready to activate once you land. This saves the hassle of buying a physical SIM card in Santo Domingo, which can be time consuming. As far as eSIM providers go, Airalo has been reliable for us in the past.
Uber operates in Santo Domingo, making it a convenient and affordable option for getting around. Uber availability may be limited in remote areas. Taxis are readily available, but always agree on a fare before starting the ride or use meter. Car rental services are available but caution is required when driving as the driving style can differ from other countries. It is NOT ADVISABLE to use public transport, this includes public buses or motorbike-style taxis.
The Dominican Republic's voltage is 110V and the plug type is A/B, the same as the United States of America.
The official language of the DR is Spanish. Although English is understood in tourist areas, it can be beneficial to know a few simple Spanish phrases to get you by.
The Dominican Republic has a tropical climate, meaning it's warm (or hot, depending who you ask) and sunny all year-round. Light, breathable clothing is definitely recommended.
Local cuisine is hearty. Plantain dishes, rice, pork and stewed beans are very common. Try arroz con habichuelas y carne, tostones, chicharrón, mangú, mofongo, sancocho, moro, and pastelón de plátanos maduros. The Dominican Republic's favorite beer is Presidente. Street food can be tempting and is generally OK, but, like many tourist destinations, be mindful of hygiene standards to avoid health problems. DO NOT drink tap water. Always drink bottled water, which is readily available.
The Dominican peoples are friendly and welcoming, a smile goes a long way. When meeting someone, a handshake or a kiss on the cheek (for women) is common. The term "mucho gusto" means pleased to meet you. Tipping is appreciated but not mandatory, although generally a 10% tip is somewhat expected at restaurants. For hotel staff, tipping 1 or 2 USD per service is considered a kind gesture. When visiting religious sites, conservative clothing is recommended (shoulders covered).
In the Dominican Republic the sun is strong, so use plenty of quality sunscreen, wear a hat when possible and drink plenty of (bottled) water. Insect repellent is helpful, especially at dawn and dusk, although mosquitos aren't quite as ravenous as those found in other countries and leave a gentle bite.
Popular items to buy while in the Dominican Republic include amber, larimar, cigars, rum, handcrafted jewelry and art. Bartering is common in market/street settings, but be respectful and keep it friendly.
Stay in tourist-friendly areas. While the country is generally safe, stick to well populated tourist areas and avoid walking alone at night in unfamiliar neighborhoods. Don't flash valuables. Keep jewelry, cameras and electronic devices out of sight when not using. Use hotel safes when available and store your valuables at your hotel. Be cautious of street vendors, most are friendly but can over price goods. Be street smart, and use common sense when in public.
