Bottom line: the pass pays off only from roughly the fourth paid site within two days. 2026 prices are €70 (2 days), €90 (4 days) and €110 (6 days), covering unlimited entry to 50+ museums and monuments. A typical 2-day combo — Louvre €22 + Orsay €16 + Orangerie €12.50 + Sainte-Chapelle €13 — totals €63.50, so you only start saving on a fifth visit. The 4-day pass at €90 is the sweet spot: 6-7 museums across 4 days saves €30-50. Important caveats: the pass does not include timed reservations (you still book slots at the Louvre, Orsay and Orangerie), and it excludes the Eiffel Tower, the catacombs, boat cruises and most temporary exhibitions. Skip it if you're visiting under 48 hours, only plan 2-3 museums, or travel with under-18s who already enter free.
