Why visit Dominica

Dominica is a small, English-speaking island in the Caribbean. It covers just 751 km² and has about 65,514 people. It suits a slow, independent trip between coastal towns such as Roseau, the capital, Portsmouth and Castle Bruce. The best months to go are January and February. One honest limitation is that there are no big cities. Roseau has about 16,571 people and Portsmouth about 3,633, so expect small-town life, not city life. Cars drive on the left.

  • A small, mountainous island

    Dominica packs 751 km2 of land into a rugged shape, with a population of just 65,514. The terrain is steep and volcanic, giving the island its nickname as the 'Nature Island' of the Caribbean.

  • Dry season from January to February

    The best months to visit are January and February, when rainfall is lower and conditions are drier across the island. This makes these two months the most reliable window for outdoor plans.

  • Roseau, the compact capital

    Roseau is Dominica's capital and largest city, with a population of 16,571. It sits on the coast, making it a natural base for exploring both the sea and the interior.

  • Portsmouth on the north coast

    Portsmouth is Dominica's second town, with 3,633 people, and lies on the coast in the north of the island. It offers a quieter, smaller-scale alternative to the capital.

  • English-speaking and easy to navigate

    English is the official language, and the island uses the Eastern Caribbean dollar. Cars drive on the left, and the time zone is UTC-04:00 year-round, with no clock changes to plan around.

Food to try in Dominica

Callaloo soup

A thick green soup made from dasheen leaves, coconut milk, and often crab or pork. It is a staple found in homes and local restaurants across Dominica.

Mountain chicken

Despite the name, this is a large frog legs dish, once a national specialty. It is less common now due to conservation concerns but still appears on some menus.

Dominican-style crab backs

Crab meat is seasoned, mixed with breadcrumbs or spices, and served back in the shell. It is a popular starter at local eateries and during festivals.

Saltfish and bakes

Shredded salted cod is sautéed with onions and peppers, served with fried bakes (a type of fried bread). It is a common breakfast dish found in markets and cafés.

Bush rum punch

A spiced rum drink made with local Dominican rum, often flavored with fruit juices and spices. It is widely enjoyed at bars and during social gatherings.

Provision and fish

A hearty meal combining boiled root vegetables like yam, dasheen, and breadfruit with fresh fish, often grilled or stewed. It is a traditional, filling dish found in many local homes and restaurants.

Know before you go

  • Plugs and voltage: Dominica uses type G plugs, the three-pin square style also used in the UK. The voltage is 230 V. Bring an adapter, and check that your chargers and devices work at 230 V.
  • Driving side: Traffic drives on the left. If you come from a country that drives on the right, plan for extra care at junctions and on your first few drives.
  • Emergency number: Dial 999 for emergencies. Save it in your phone before you arrive so you do not have to search for it when you need it.
  • Currency: The local currency is the Eastern Caribbean dollar. Check the current exchange rate before you travel so you can judge prices quickly.
  • Language: English is the official language. Signs, menus and everyday conversations are usually easy to follow for English speakers.
  • Time zone: Dominica is on UTC-04:00. Check the difference from your home time zone so you can plan calls and connecting flights.
  • Phone calls: The country calling code is +1, the same code used by the USA and Canada. Ask your provider about roaming charges before you travel, because the shared code does not mean domestic rates apply.
