Roman Ruins of Conímbriga & Sicó Caves: 4-hour tour

The caves at Casmilo were once underground until the limestone collapsed and opened them to the sky.

A four-hour tour of the Roman Ruins of Conímbriga and the Casmilo Holes near Coimbra, departing at 9 a.m. with a qualified guide, private transport and entry to the Monographic Museum included. The route moves from the Roman complex through the Sicó limestone massif to the exposed cave formations, and includes the Moorish Waterfall in winter months.

The experience

The tour starts at 9 a.m. and covers two distinct geological and historical sites within the Sicó region. You begin at the Monographic Museum and Roman Ruins of Conímbriga, where the architectural remains show how the Roman Empire shaped daily life in this area: mosaics, walls and domestic layouts survive from centuries of occupation. From there the route heads into the limestone landscape toward Casmilo Holes, where underground cave systems have collapsed over time, leaving dramatic rock formations exposed at the surface.

A qualified guide leads the group throughout the four hours, speaking English or Portuguese depending on your preference. Private transportation is included, so the route between sites is handled without arranging a separate vehicle. In winter months, the itinerary also passes the Moorish Waterfall, adding a third natural feature to the day. Photos of the tour are provided afterward.

The tour suits visitors of any fitness level and allows service animals. Public transportation options exist nearby if you prefer to arrange your own arrival, though pickup is included in the booking. Personal accident and liability insurance covers the group for the duration.

Casmilo Holes are collapsed limestone cave formations that are now exposed to the surface, so they are open geological features rather than underground passages.
