The Main Ridge Forest Reserve protects the central spine of northeastern Tobago — a cloud-draped ridge of tropical rainforest that runs for most of the island's length. The forest is genuinely ancient: mahogany, teak, and immortelle trees rise to 30 metres, and the canopy is alive with the calls of mot-mots, trogons, and the rufous-vented chachalaca (Tobago's national bird). Several marked hiking trails cross the reserve, ranging from an easy 2-km walk from the Roxborough-Bloody Bay road to longer ridge hikes that reward with views of both coasts.
The best birding is at dawn and dusk when the forest is most active. Over 200 bird species have been recorded on the island, of which perhaps 130 can be found in or near the reserve. The forest also shelters agouti, armadillo, tree boas, and fer-de-lance, though the last is rarely encountered on the main trails. Guides can be arranged through operators in Speyside or Roxborough — local guides know the bird calls and can spot species you'd walk past entirely.
