Riviera River Cruises' two new ships launching in 2025 will sail itineraries on the Danube and Douro rivers.
The Riviera Radiance will sail six Danube itineraries, including one exclusively for solo travelers and three holiday itineraries.
The Riviera Rose will sail one itinerary on the Douro River in Portugal and Spain.
On the Danube, the Radiance will sail Riviera's classic and holiday itineraries through Hungary, Slovakia and Austria as well as a 15-day itinerary to the Black Sea and back.
Riviera Rose will sail the eight-day Highlights of the Douro Valley & Salamanca.
The 443-foot Riviera Radiance will have 89 cabins. The 262-foot Riviera Rose will have 57.
Riviera announced the new ships two weeks ago, noting that the river line is including "Riviera" in the ships' names for the first time. Riviera's existing ships are named for British authors.
