8:30 AM — Departure from Beirut Your professional guide and driver collect you from your Beirut hotel and head north through the Dog River valley — its canyon walls carved with inscriptions left by Egyptian pharaohs, Assyrian kings, and Roman emperors — toward Jeita Grotto.

The day begins beneath the earth. Jeita Grotto is a UNESCO tentative World Heritage Site and a top-five finalist in the New 7 Wonders of Nature — two interconnected limestone caves stretching 9 kilometres beneath the Lebanese mountains. The upper cave is explored on foot through an elevated walkway where stalactites and stalagmites up to 8 metres tall hang and rise in formations of extraordinary beauty, built over millions of years. The lower cave is navigated by silent electric boat along an underground river through chambers where the silence feels complete and the formations seem almost deliberately sculpted. Your guide explains the geology behind every formation you pass — turning one of Lebanon's greatest natural wonders into something you genuinely understand as well as experience.

Before the temples, stop at the ancient Roman quarry where the Stone of the Pregnant Woman still lies exactly where it was cut 2,000 years ago — a single limestone block 21 metres long and weighing an estimated 1,000 tonnes, never moved and never finished. After the natural scale of Jeita, this man-made monument sets the extraordinary human scale of what awaits at the temple complex just minutes away.

Enter the greatest Roman temple complex on earth. The Temple of Jupiter stands on Trilithon stones each weighing over 800 tonnes — the largest dressed stones ever used in construction in human history. Six of its original 54 columns still stand at 22 metres tall. The Temple of Bacchus, larger than the Parthenon in Athens and almost entirely intact, is the best-preserved Roman temple in the world. The circular Temple of Venus completes a complex that has stood for two thousand years at the crossroads of civilisations. Your guide brings the full extraordinary story of Baalbek — Phoenician sacred site, Roman sanctuary, Byzantine church, Arab fortress — to life within these magnificent walls.

Lunch in Baalbek — optional A well-earned break at one of Baalbek's local restaurants — hearty Bekaa Valley mezze, grilled meats, and fresh flatbread in a town that has been feeding travellers for two thousand years. A natural pause between the temples and the wine cellars ahead.

The day ends underground again — but this time in a very different world. Chateau Ksara is Lebanon's oldest winery, founded by Jesuit monks in 1857 and now the country's largest wine producer. The highlight is the extraordinary Roman cave cellar system stretching 2 kilometres beneath the winery — ancient tunnels discovered by the Jesuits in the late 19th century, where wine ages at a naturally constant temperature year-round. After a morning in Jeita's natural caves and an afternoon at Baalbek's monumental Roman stones, descending into Roman wine caves creates a remarkable final chapter — three underground worlds in a single day, each shaped by a different force across a different millennium. The tasting showcases Ksara's iconic Cabernet-Syrah blends, crisp Blanc de Blancs, and beloved Sunset Rosé.
