Rota da Água crosses Nasce Água and Serra do Morião by following traces of different uses of water. Five ruined mills beside Ribeira dos Moinhos mark the beginning and recall the water power that supported local activity. The ascent passes Mãe-de-Água, a spring, and a small hydroelectric installation, bringing walkers close to structures created to collect, channel and regulate water.
A reservoir receives water associated with Furna d’Água and Cabrito before the path enters natural vegetation in an area important for infiltration. Cruzeiro and Serra da Costaneira lead to the high point, with views over Angra do Heroísmo, Monte Brasil and the south coast in clear weather. The return repeats much of the route with one small variation. The walk turns discreet infrastructure, springs and ruins into a reading of water, showing links between volcanic relief, energy and urban supply.
The mill ruins appear at the beginning, while the spring, hydroelectric installation and reservoir are encountered progressively on the ascent. This order lets walkers follow water from traditional uses towards more recent technical structures before reaching the summit view, where the broader relationship between hillside, city and coast becomes visible.
