Pinar del Río's most discovered 'undiscovered' beach is the 3km-long blanket of sand that adorns the northern coast of Cayo Jutías, a mangrove-covered key situated approximately 65km northwest of Viñales and attached to the mainland by a short pedraplén (causeway). Jutías – named for its indigenous tree rats – vies with Cayo Levisa to the east for the title of the province's most picturesque beach, and while the latter might be prettier, the former has no overnight accommodation and thus greater tranquility.
The Cayo's access road starts about 4km west of Santa Lucía. Ten minutes after crossing the causeway the Faro de Cayo Jutías appears; this metal lighthouse was built by the US in 1902 and makes for an interesting walk along the abutting mangrove-studded sands. The road kinks sharp left to culminate at the main Jutías beach, caressed by crystal-clear water, 12.5km from the coastal highway.
