This easy trail traces the early history of electricity production on São Miguel, pioneered by engineer José Cordeiro (1867-1908) in the late 19th and early 20th centuries. From the Parque Escutista dos Lagos, it crosses a gate by the stream to a water reservoir that once supplied the Fábrica da Cidade (1904-1974), a plant now replaced by the Mini Hydric Central of Ribeira da Praia, built in 1990.

The route continues down past the ruins of the Fábrica da Cidade and a detour to the old loading chamber of the Fábrica da Vila, before reaching the base of a waterfall where the ruins of the Fábrica da Vila (1899/1900-1972), the oldest of the four plants, still stand. From there, a wooded path parallel to the stream leads past two swimming spots, the Cascata do Segredo waterfall and the Poço dos 30 Reis pool.

The trail follows an old water pipe to Lugar da Praia, near the small museum dedicated to the island's early electricity industry, the Fábrica da Praia (1911-1974), which can be visited by prior arrangement. At about 2.1 km and 90 minutes, with around 240 m of climbing and descending each way, this short walk packs in a surprising amount of up and down.

What to know

Start & finish
Parque Escutista dos Lagos to Lugar da Praia
Safety
Watch your footing around the old industrial ruins and near the waterfalls and swimming pools; if you swim, check the water's depth and current first.
When to go
The swimming spots at Cascata do Segredo and Poço dos 30 Reis are most inviting in summer; the stream runs higher and the path muddier after rain.
