Portsmouth offers the visitor a wonderful historical experience through the Indian River and Fort Shirley. A trip up to the Indian River is a delightful, relaxing ride where the mangrove, swamp and wildlife can be seen at close quarters. Hike to Morne Diablotin, the tallest mountain of Dominica. Or take a gentler hike along the Syndicate Trail to discover the Sisserou parrot, which is the only endemic species of that kind in the region.
