The Faro Mazatlan sits on top of Crestón Island, a 157-metre rocky headland at the southern entrance to the city's harbour. Crestón is connected to the mainland by a short causeway, and the lighthouse is reached by a paved switchback path that climbs through scrub and cactus. The walk takes 25 to 40 minutes depending on pace; the view from the top covers the city, the harbour, the headlands, and on a clear day all the way north to the Zona Dorada.
A glass skywalk was added at the summit in 2018, extending out from the rock for visitors who don't mind heights. Go early — the path is exposed and the climb in the afternoon sun is unpleasant. There is a small entrance fee. Bring water.
