Sierra Cristal National Park, National park in Holguín Province, Cuba

Sierra Cristal National Park is a mountainous area in Holguín Province covered with pine forests and home to various animal species. The terrain includes multiple hiking trails where visitors walk through the landscape and experience the natural surroundings up close.

Cuba's first national park was created by presidential decree on 24 April 1930, initially covering 26,800 hectares; by 1958 it was acknowledged that little conservation work had been done. The mountains had earlier sheltered rebelling slaves during the colonial era, and in the 1950s the area served as a base for insurgent activity during the Cuban Revolution.

The summit of Pico Cristal is crowned by a bust of Major General Calixto García, placed there in 1986 and treated as a patriotic landmark of the region. The sierra also served as a refuge for rebelling slaves during the colonial era and as a base for insurgent activity in the 1950s.

Access is from Holguín via the national road to Mayarí, then dirt secondary roads into the park; from Santiago de Cuba the route runs through Segundo Frente. The terrain is steep and karstic, so four-wheel-drive vehicles are recommended and road conditions should be checked before travelling, especially in the rainy season.

The summit of Pico Cristal is crowned by a bust of Major General Calixto García, installed in 1986. The peak is the highest point of Holguín Province, though sources give its elevation as either 1,231 or 1,300 metres. The park's vegetation includes around 535 plant species, about 300 of them endemic to Cuba.
