Dominica by Catamaran: The Wild Nature Stopover of the Antilles

Dominica is the stopover that transforms a Caribbean cruise. Nicknamed “the Nature Island”, it is the most unspoiled of the Lesser Antilles: tropical forest covering two thirds of its territory, 365 rivers, active volcanoes, and waters inhabited year-round by sperm whales, a situation found nowhere else in the world. From Guadeloupe, the crossing to Portsmouth takes two to three hours on a broad reach, roughly 25 nautical miles. On arrival, Prince Rupert Bay, the Indian River and the hot springs of Wotten Waven form a stopover unlike any other in the Caribbean. This article details the anchorages, the activities ashore and underwater, the entry formalities and the best time to sail there from the Sailoe base in Guadeloupe.

Why is Dominica different from the other Caribbean islands?

Dominica has no golf, no resort complexes, no endless white-sand beaches. That is precisely what makes it the most sought-after stopover for sailors who have already toured the classic islands. The island is volcanic, densely covered in primary forest, with two thirds of its surface classified as a protected natural area, and crossed by more than 365 rivers. It has been independent since 1978 and is still home to an Amerindian community, the Kalinago, the only surviving Carib population in the Lesser Antilles. From the sea, the island’s silhouette announces itself before any other: a green, mountainous mass, radically different from the flat profiles of the low-lying islands nearby.

A volcanic island within 25 miles of Guadeloupe

From the north of Guadeloupe, Portsmouth lies about 25 nautical miles away. With a steady trade wind carrying you on a broad reach, the crossing takes two to three hours by catamaran. This channel between the two islands is one of the most pleasant in the Lesser Antilles: the wind is steady, the sea well formed but not uncomfortable, and marine wildlife sightings begin while still under way. The Morne Trois Pitons National Park, which covers a significant part of the island, has been a UNESCO World Heritage Site since 1997.

What are the best anchorages for a catamaran in Dominica?

Two main anchorages structure the stopover: Prince Rupert Bay to the north (Portsmouth) and the Roseau anchorage to the south. One gives access to the Indian River, Fort Shirley and the PAYS guides; the other is the entry point for the hot springs, the waterfalls and the official formalities. Most crews choose to start with Portsmouth before heading down to Roseau, following the island’s natural geography.

Portsmouth and Prince Rupert Bay - the northern anchorage

Prince Rupert Bay is a vast, well-protected bay, with grassy seabeds between 3 and 5 metres. Mooring buoys are available. As soon as you arrive, members of PAYS, the Portsmouth Association of Yacht Security, a local organisation founded in 2005, come aboard by dinghy to offer their services: night-time security, fresh water, WiFi access, and above all the organisation of excursions to the Indian River with certified guides. It is from this anchorage that you also visit Fort Shirley, 18th-century military ruins perched on the heights overlooking the bay, with a striking panorama over the island’s north coast.

Roseau - the capital and the southern anchorage

At Roseau, the seabed is deeper, often beyond 20 metres near the beach. Mooring buoys are offered by the local boat boys. The ferry terminal, a few minutes’ walk or dinghy ride from the anchorage, houses the customs, immigration and port authority services all in one place: clearance takes about 30 to 45 minutes. Roseau is a town with well-preserved colonial architecture, with its covered markets and colourful buildings. It is also the logistical starting point for the hot springs and Trafalgar Falls.

What to do at the Indian River during a stopover in Portsmouth?

The Indian River is the main excursion from Portsmouth. You make your way upstream aboard traditional boats steered by local guides, through a mangrove of bwa mang, giant mangrove trees with twisting roots that form a leafy vault above the water. The river is navigable for about 45 minutes by boat. The atmosphere is unique: absolute calm, filtered light, discreet wildlife. This river was chosen as a filming location for Pirates of the Caribbean. The PAYS guides in Portsmouth organise the trips and are the official contacts for the excursion.

Which hot springs and hikes can you discover from the anchorages?

Dominica’s volcanic activity rises to the surface in several dozen natural springs. The most accessible from Roseau is Wotten Waven, a village tucked into the forest about twenty minutes by taxi from the anchorage. The island combines an active underwater volcano, accessible thermal springs and hikes through intact primary forest, a combination found on no other Caribbean island.

Wotten Waven and its natural sulphur baths

Wotten Waven has at least 6 natural bathing sites available to visitors. The water, heated by the volcanic activity of Morne Trois Pitons, is rich in sulphur minerals and prized for its therapeutic effects. The pools are in the open air, surrounded by dense tropical vegetation, with plumes of steam rising between the foliage. The atmosphere is authentic, far from hotel tourist infrastructure. Most sailors make this a day excursion from Roseau, by shared or private taxi.

Trafalgar Falls and the Boiling Lake

Trafalgar Falls, two distinct cascades known as the Mother and the Father, meet in a natural pool where cool waters mingle with hot springs at around 40 °C below. They are reached after a short hour’s walk from the road. More demanding, the hike to the Boiling Lake requires about 3 hours of strenuous walking from Roseau. This volcanic lake in the Morne Trois Pitons National Park holds water at around 82 °C, in permanent ebullition, surrounded by sulphurous vapours: a geological spectacle unlike any other in the Antilles. Nearby, the Titou Gorge offers a natural pool set deep into the rock, ideal for a recovery swim after the hike.

Which marine animals can you observe from a catamaran off Dominica?

Dominica is the only place in the world where sperm whales live year-round. From a catamaran sailing between Guadeloupe and Dominica, or off the island, cetacean sightings are part of the journey itself. In all, 22 species of cetacean have been recorded in these waters. The crossing from Guadeloupe is already an opportunity for observation: the stability and elevated viewpoint from the deck of a catamaran are a real advantage over a monohull sailboat.

Between November and March, the chance of spotting humpback whales or sperm whales from the deck approaches 90%. This is also when humpback whales arrive to give birth in the warm waters of Dominica, before heading back to colder seas. Outside this window, sperm whales remain present year-round and dolphins are almost a daily sight on the crossings. Beneath the surface, Dominica’s seabeds are among the richest in the Lesser Antilles: black coral (a rare species), gorgonians, brain coral, angelfish, barracudas, rays and sea turtles. At Champagne Beach, a snorkelling site south of Roseau, geothermal bubbles rise naturally from the seabed, an underwater experience unlike any other.

What are the entry formalities for a catamaran in Dominica?

Dominica has been an independent state since 1978. Entry by catamaran requires clearance in one of the three official ports, plus a few simple documents. Dominica is not a French territory: the rules differ from those of the neighbouring islands under French jurisdiction.

The official ports of entry are Roseau, Portsmouth and Anse du Mai (east coast, little frequented). Clearance is done at the ferry terminal in Roseau or in Portsmouth, with customs, immigration and the port authority grouped together. For French nationals, a valid passport is strongly recommended: according to the French Ministry of Foreign Affairs, a national identity card is only accepted when arriving directly from Martinique or Guadeloupe, and the Dominican authorities may refuse it. A passport is required for stays of more than 30 days and for all non-EU nationals. A visa is issued free of charge on arrival for European Union nationals. The local currency is the Eastern Caribbean dollar (XCD); the euro is accepted in many shops. As a guide, 1 EUR is worth around 3.15 XCD (a rate that varies with the market). Official language: English (Creole is also spoken). Please note: perishable foodstuffs cannot be imported. Any movement between ports within Dominica requires prior authorisation from the authorities.

What is the best time to visit Dominica by catamaran from Guadeloupe?

The dry season from December to May matches exactly the Caribbean charter window. It is also the best time to sail and to observe cetaceans. Temperatures range between 25 and 30 °C, the water is 26-28 °C and the trade wind is established. The wet season, from June to October, brings frequent showers and a cyclone risk from August to October, when sailing is not advised. The window from November to March is particularly favourable for spotting humpback whales, on top of the permanent presence of sperm whales.

From the Sailoe base in Guadeloupe, Dominica features in every winter cruise itinerary between December and April. The island is often combined with Les Saintes, Marie-Galante or Martinique to make up a varied week of sailing, between lively anchorages and nature stopovers.

Frequently asked questions about Dominica by catamaran

What are the must-do things in Dominica?

The must-do stopovers from a catamaran are the Indian River by boat from Portsmouth, the Boiling Lake in the Morne Trois Pitons National Park (UNESCO-listed in 1997), the hot springs of Wotten Waven, Trafalgar Falls, and snorkelling at Champagne Beach with its geothermal bubbles. Dominica is the only Caribbean island to combine an active underwater volcano, thermal springs accessible from the anchorages and a resident sperm whale population present year-round.

How do you get around the island of Dominica from the catamaran?

From the Portsmouth or Roseau anchorages, excursions are made mainly by taxi, with fares to negotiate directly. In Portsmouth, the PAYS organisation centralises the official certified guides and arranges transfers to the Indian River. For hikes in the national parks (Boiling Lake, Morne Diablotin), a local guide is strongly recommended: the trails are technical and the weather conditions changeable.

What is the best season to visit Dominica?

The dry season from December to May offers the best sailing and hiking conditions. Tropical showers are less frequent, the cyclone risk is nil, and the trade winds are steady. It is also the humpback whale observation period (November to March) and the sperm whale nursery season. The seabeds are visible in good weather, with particularly clear water at the end of the dry season.

Are there any special formalities for entering Dominica by boat?

Yes. Dominica is an independent state and requires clearance in one of the three official ports (Roseau, Portsmouth or Anse du Mai). A passport is required for all nationals, with the identity card accepted for French nationals for a stay of up to two weeks. A visa is issued free of charge on arrival for EU nationals. Importing perishable foodstuffs is prohibited.

Can you see whales from a catamaran in Dominica?

Yes. Dominica is the only place in the world where sperm whales live year-round. Between November and March, the chance of spotting humpback whales or sperm whales from the deck approaches 90%. In all, more than 22 species of cetacean have been recorded in these waters. During the crossing from Guadeloupe or towards Martinique, dolphins and cetaceans are frequently visible from the deck, and the stability of a catamaran makes these sightings at sea easier.
