Puerta de Ancón
A karst gap constituting the natural passage for communication between Viñales Valley and San Vicente Valley. This is where the presence of the Jurassic Period was first reported in Cuba, a magnificent geological and geomorphological observatory.
- Boundary between Viñales Valley and San Vicente Valley
Cuevita Valley
A contact polje located about 2 km east of Ancón Gap. The great activity of fluvial erosion can be observed, combined with ascending neotectonic movements.
- Cuevita Valley
Hoyo de Jaruco
A sinkhole with almost perfect geomorphology, presenting the geosite as a set of several places of geomorphological, paleontological, and pictographic interest.
- La Jutía Valley
Santo Tomás Polje
A valley of fluviokarst origin, a contact polje due to the narrow relationship between the terrigenous sequences of APS and the units of the FCC.
- El Moncada
Boquerón del Infierno
The deepest inactive fluvial channel in Cuba, observed in the mountains of the same name, an incision in the mountain range over 150 m deep.
- Infierno Mountains
Viñales Valley
A contact polje, precisely given by the contact between the APS and the FCC. A broad development of tower or conical karst is observed, represented by the mogotes, in a valley with an almost flat bottom.
- Viñales Valley
Dos Hermanas Valley
An excellent example of a karst landscape, the entrance to the valley is marked by a large inactive fluvial canyon with vertical walls formed by the Tumbadero Mountains (Mogote valley) to the east and the Dos Hermanas Mogote to the west.
- Dos Hermanas Valley
Laguna de Piedras
A clear example of the karst morphology of the area and the entire Los Órganos Mountains Range. A lagoon surrounded by lapiaz in a sinkhole whose bottom is occupied by clays accumulated by washouts.
- Laguna de Piedras
Hoyo de Jaruco Gap
A narrow and steep gap, access to the Hoyo, excavated by the dissolutive action of water, corresponding to an inactive fluvial channel with an approximate depth of about 100 m.
- La Jutía Valley
Mogote El Lele
Composed of limestones from the Guasasa Formation, it appears as a unique karst structure in the center of the valley with the development of “Caves at Foot” or “Fuss Höhlen”.
- El Capón
