Tunnels are required to provide a low gradient route through the mountains of the Venezuelan Coastal Range. Bárbula Tunnel takes its name from Bárbula, a locality near Naguanagua.

They were known to the locals and Humboldt noticed that sick people were taking steam baths there. On his return to Europe, Humboldt made Las Trincheras known to science. He had recorded the temperature of the water as . There was no evidence of vulcanism in the area to explain what was heating the water. The work of François Arago on the geothermal gradient helped Humboldt to develop the idea that the springs obtained their heat from very ...
