Railbookers · Independent rail package
12-day luxury rail journey from Istanbul to Paris and London
Railbookers lists this 12-day, 11-night rail package as a route aboard the Golden Eagle Danube Express, running from Istanbul through Paris and finishing in London. The operator describes curated excursions in each city along the way, including the ancient streets of Sofia, alongside sumptuous accommodations and gourmet dining. It is framed as an independent rail package rather than an escorted tour, so travellers manage their own days between stops. Priced from $28,049 per person, it extends the Istanbul to Paris route with an additional finish in London, suiting travellers drawn to history, comfort and a named luxury train rather than a guided group itinerary.
