Debuting in 2026 as part of Tauck's Destination Fleet, the 410-foot (125-meter) ms Serene is a purpose-built riverboat designed for the Seine, carrying no more than 124 guests for an unusually spacious and intimate cruising experience. Her reimagined deck plan devotes more room to each stateroom and to shared public spaces, with roughly 80 percent of cabins measuring 225 square feet or larger.

Accommodations aboard ms Serene include 20 expansive 300-square-foot Tauck Suites featuring separate showers and walk-in closets, alongside roomy 225-square-foot and 180-square-foot cabins. Sailing round-trip itineraries between Paris and Normandy, she pairs Tauck's signature all-inclusive service and guiding with the comfort of one of the most generous space-per-guest ratios on Europe's rivers.
