The municipality of Tivissa, which is in the Ribera d’Ebre district in the south of Catalonia, stretches from a plain to the right of the Ebro River to the Mediterranean. It borders the districts of Priorat, Baix Camp and Baix Ebre and covers 208 km2, which makes it the sixth largest municipality in Catalonia.

There are four towns in the municipality, La Serra d’Almos, Darmós, Llaberia and Tivissa, which the municipality is named after.

Tivissa is a very mountainous area on the southern branch of the Catalan coastal mountain ranges, made up of the Cardo, Tivissa i Vandellòs and Llaberia mountains and the Colldejou massif.

The highest spot height is in the east, La Miranda de la Serra de Llaberia (919.3 m). The height falls in the west and the Plana del Burgar plane stretches to the south, separating the Tivissa and Cardo mountains. To the northwest the area reaches Cubeta de Móra and the Ebro river, which is where the municipality is at its lowest.

The most notable summits in the Tivissa mountains are Jovara (776 m), Punta del Corb (695 m), Tossa (720 m) and Coll del Ventall (535 m).
Various gullies cut through the land. Some of the streams are tributaries of the Ebro while others flow straight into the sea. These gullies include Darmós, d'Atarosses, Molló, Banyoles and Burgar, etc.

Crops are ever-present in the Tivissa countryside, mainly almond trees, olive trees, vines and fruit trees.

Surrounded by mountains, Tivissa has steep relief with calcareous rocks that are unbeatable for climbing.

 Tivissa has a Mediterranean climate similar to the coast but with a little continental influence.

A Mediterranean low coastal hill climate is the prevailing climate in most of Tivissa. Temperatures fall as the altitude rises but it is still quite dry in the summer, as is usual for that kind of climate.

The winter temperatures range from 5°C to 10°C. Winter lasts three months in both Tivissa and Móra (December, January and February).
The summer is hot and long, although since the town of Tivissa is on top of a hill, the temperature is always a bit cooler than on the plains in the surrounding district.

Precipitation is very irregular. It is heavier in the autumn and gentler in the spring, but there are few days in the summer when it rains.
