Dominica contains 365 rivers according to the marketing phrase, though the exact count varies by seasonal flow. The Layou River is the longest. Morne Trois Pitons National Park became a UNESCO World Heritage Site in 1997 and contains Boiling Lake, the second-largest thermally active lake globally after Frying Pan Lake in New Zealand. The lake sits approximately 10.5 kilometers from Laudat village and requires a six-hour round-trip hike through the Valley of Desolation, an area of active fumaroles and hot springs. Water temperature at Boiling Lake reaches 82 to 91.5 degrees Celsius at edges where measurement is possible. The lake dimensions fluctuate; after Hurricane Maria in September 2017, water levels dropped significantly before gradually refilling.
The Waitukubuli National Trail spans 184 kilometers across the island from Scotts Head in the south to Cabrits in the north, divided into 14 segments. Waitukubuli means "tall is her body" in the Kalinago language, referring to the island itself. The trail opened in 2011 as the Caribbean's first long-distance hiking trail. Segment 5 passes through the Morne Trois Pitons National Park and includes the steepest elevation gain. Most hikers complete the trail in sections over multiple days rather than through-hiking. The trail passes through forests, Kalinago Territory, coastal areas, and farms.
Trafalgar Falls consists of two waterfalls visible from a single platform: the taller Father Falls at approximately 38 meters and the wider Mother Falls. The site is 15 minutes by vehicle from Roseau. After Hurricane Maria destroyed the original platform and access paths, reconstruction created new viewing platforms by 2019. Visitors can wade into the pools at the base of the falls where hot and cold streams mix from geothermal and freshwater sources. The hike from the parking area to the viewing platform takes 10 minutes on a paved but steep path.
Titou Gorge is a narrow volcanic gorge with a swimming route of approximately 60 meters through water averaging 1.5 meters deep. A small waterfall at the far end cascades into the gorge. The entrance pool appears in the 2006 film "Pirates of the Caribbean: Dead Man's Chest." Water temperature stays between 18 and 22 degrees Celsius. Life jackets are available but not mandatory. Hurricane Maria caused significant rockfall and the site reopened in phases starting in 2019 with enhanced safety monitoring. The gorge is 10 minutes by vehicle from Laudat.
Emerald Pool sits within Morne Trois Pitons National Park, accessible via a 20-minute loop trail from the road between Castle Bruce and Pont Cassé. A 12-meter waterfall feeds the pool. The name derives from the green tint created by surrounding vegetation reflecting into the water. Steps and railings installed in the 1990s make the path accessible, though Hurricane Maria damaged sections that were subsequently repaired. Swimming is permitted. The site receives heavy tourist traffic, with crowds typically largest between 10 a.m. and 2 p.m. when cruise ship passengers visit.
Morne Diablotin rises to 1,447 meters as Dominica's highest peak. Morne Diablotin National Park protects 3,400 hectares of montane forest. The Syndicate Nature Trail within the park provides primary access to view the endangered Sisserou parrot, Dominica's national bird, and the Jaco or red-necked parrot. The Sisserou parrot population was estimated at 400 birds before Hurricane Maria; post-hurricane surveys in 2018 confirmed only 80 to 120 individuals survived. The summit trail from the Syndicate Estate is approximately 6 kilometers round trip with significant elevation gain and typically requires four to six hours. The trail becomes extremely muddy and requires good physical conditioning.
Cabrits National Park on the northwest coast contains Fort Shirley, a British garrison built in 1763 after the Treaty of Paris transferred Dominica to British control. The fort complex included over 50 structures at its peak. Restoration work began in 1982. Visitors can walk through restored barracks, the officers' quarters, and powder magazines. Interpretive signs detail the fort's role in defending Prince Rupert Bay. The park also protects 531 hectares of tropical forest and wetlands. A walk around the fort complex takes approximately one hour. The site offers views over Portsmouth and Prince Rupert Bay.
Scotts Head is a village at the southernmost point where the Atlantic Ocean meets the Caribbean Sea. The peninsula creates Soufrière Bay to the south. Scotts Head Marine Reserve established in 1987 protects coral reefs, seagrass beds, and volcanic underwater features. The Champagne Reef approximately 500 meters offshore releases volcanic gases through vents in the seafloor, creating the visual effect of diving in champagne. Water temperature at the vents can reach 30 degrees Celsius compared to 26 degrees in surrounding water. Visibility typically ranges from 15 to 30 meters. The site is accessible directly from shore.
