Dominica is the most mountainous island in the Lesser Antilles. The island measures 47 kilometers long and 29 kilometers wide. Morne Diablotin reaches 1,447 meters, making it the highest peak in the Windward Islands. The island contains 365 rivers, according to local count, though this figure appears in tourism materials more than geological surveys. The Layou River is the longest. Nine active volcanoes shape the terrain. Boiling Lake, located in Morne Trois Pitons National Park, is the second-largest thermally active lake in the world after Frying Pan Lake in New Zealand. The island sits between Guadeloupe to the north and Martinique to the south in the Caribbean Sea.
The terrain prevents beach tourism at Caribbean scale. Dominica has approximately 15 kilometers of sandy beaches compared to hundreds of kilometers on neighboring islands. Most coastline is rocky volcanic cliff. This geography filtered out large-scale resort development through the 1970s and 1980s when other Caribbean islands built hotel infrastructure. Douglas-Charles Airport on the northeast coast cannot accommodate wide-body jets. The runway measures 1,829 meters. Travelers connect through Antigua, Barbados, Guadeloupe, Martinalia, or Saint Lucia. Flight frequency from North America requires overnight connections in most cases.
Hurricane Maria made landfall on September 18, 2017, as a Category 5 storm with sustained winds at 260 kilometers per hour. The storm destroyed an estimated 90 percent of island structures. Roseau, the capital, lost most roofing. The agricultural sector collapsed. Economic output fell 14 percent in 2017. Electricity restoration took 11 months for the main grid. Some rural areas remained without power into 2019. The government reported 65 deaths directly attributed to the hurricane. Tourism arrivals, already modest, fell 20 percent in the year following. Recovery funds came primarily from the Citizenship by Investment program, which grants Dominican passports starting at 100,000 USD as of 2024. This program accounts for approximately half of government revenue according to International Monetary Fund assessments.
Dominica's population was 72,737 in the 2022 census. This represents a decline from 71,293 in the 2011 census after accounting for emigration following Hurricane Maria. Portsmouth, the second-largest town, has approximately 3,000 residents. The Kalinago Territory on the northeast coast covers 15 square kilometers and holds roughly 3,000 people, the largest remaining Kalinago population in the Caribbean. The Kalinago are descendants of Indigenous Carib peoples who resisted European settlement longer here than on other islands. British forces did not secure full control until the 1763 Treaty of Paris formalized possession after decades of French-Kalinago resistance. The island changed hands between France and Britain seven times between 1635 and 1805.
English is the official language. Dominican Creole, a French-based creole, is the common language in daily life. The creole shares structure with Haitian Creole and the creoles of Martinique and Saint Lucia but remains mutually unintelligible. Radio stations broadcast in both languages. Roman Catholicism claims approximately 60 percent of the population, a legacy of French colonial influence before British rule. The Roseau Cathedral, officially the Cathedral of Our Lady of Fair Haven, dates to 1916 on a site where churches have stood since the 1730s.
Morne Trois Pitons National Park became a UNESCO World Heritage Site in 1997. The park covers 68.57 square kilometers in the southern interior. The citation emphasized the concentration of volcanic features: fumaroles, hot springs, the Boiling Lake, Titou Gorge, and the Valley of Desolation. Trails to Boiling Lake require approximately six hours round trip with elevation gain near 600 meters. The lake temperature measures between 82 and 92 degrees Celsius at the edges. The center is too dangerous for measurement. Water levels fluctuate based on underground volcanic activity. In 2004 the lake nearly dried completely, then refilled by 2005.
The Waitukubuli National Trail opened in 2011. It spans 184 kilometers from Scotts Head in the south to Cabrits National Park in the north. The trail divides into 14 segments ranging from 5 to 18 kilometers each. Segment 5, crossing Morne Diablotin, is considered the most difficult. Hikers typically complete the full trail in 10 to 14 days. The trail name comes from the Kalinago word for Dominica, meaning "tall is her body." Trail maintenance suffered significantly after Hurricane Maria. Some segments remain poorly marked as of 2024.
