The Sierra Maestra runs along the south coast of eastern Cuba, and Pico Turquino at 1,974 m is the island's high point. The approach climbs from coffee slopes into genuine cloud forest — tree fern, epiphytes, the Cuban trogon and the bee hummingbird — and from the summit ridge the Caribbean opens south with no land between you and Jamaica.
Viñales, in Pinar del Río, is a UNESCO cultural landscape and the listing is agricultural rather than scenic: limestone mogotes standing out of red tobacco soil, with the crop still worked by oxen and hand-strung in thatched curing barns. Both Cuban itineraries are inquire-only, and that is a compliance matter rather than a difficulty one.
Country-level constraints that decide whether a date is possible.
