About Boiling Lake#

The Boiling Lake is a hot, steaming lake set in the Valley of Desolation within Morne Trois Pitons National Park in Dominica. It is a volcanic feature formed by a flooded fumarole and is noted for constantly bubbling, steaming water.

Hiking to the lake is the primary reason visitors go there; the route crosses rugged, volcanic landscape and can be physically demanding. Viewing points at the lake rim allow observation of the boiling surface and fumarolic activity.

The feature is part of the island’s active geothermal and volcanic system and is monitored as part of Dominica’s natural-site management. Its thermal activity demonstrates the ongoing geothermal processes beneath the national park.

The Boiling Lake lies in Saint Patrick Parish within Morne Trois Pitons National Park on the island of Dominica in the Caribbean.

  • Ranking and origin: The lake is a flooded fumarole and is typically described as the world’s second-largest boiling lake after a larger feature in New Zealand.
  • Access: Reaching the lake requires a strenuous hike across volcanic terrain; there are no roads directly to the shore and visitors should plan for a demanding round trip.

How to Get to Boiling Lake#

The Boiling Lake trail begins near the village of Laudat in Morne Trois Pitons National Park. Hikes are typically organized by local operators in Dominica (Roseau or Portsmouth) and require a full day with a certified guide. Travel into the park is by road from Roseau, Dominica’s capital.

Tips for Visiting Boiling Lake#

  • Visit early in the day to avoid afternoon rains and to enjoy cooler temperatures on the climb.
