Morne Watt, Stratovolcano in southeastern Dominica.

Morne Watt is a stratovolcano in southeastern Dominica that rises to 1,224 meters within Morne Trois Pitons National Park. The mountain displays dark volcanic rocks and features ongoing thermal activity visible in the surrounding valleys.

The volcano produced major pyroclastic flows roughly 1,300 years ago that reshaped the southeastern landscape of Dominica. This powerful eruption left a lasting mark on the island's geology.

The Boiling Lake and the Valley of Desolation, both on Morne Watt's flank, are the best-known volcanic features in Dominica and the main attractions of Morne Trois Pitons National Park. The Valley of Desolation is where the island's only historically confirmed eruptions occurred, in 1880 and July 1997.

Visitors should wear sturdy hiking boots and carry sufficient water when exploring the marked trails through the Valley of Desolation. The terrain can be demanding and wet, so proper preparation is important for a safe visit.

The 1880 phreatic eruption at the Valley of Desolation thermal area threw ash as far as 10 km from the mountain, and a smaller VEI-1 explosion followed in July 1997. These two are the only historically confirmed eruptions in Dominica, so the summit's steam vents are the island's only record of observed volcanic activity.
