Viking will add a new vessel to its 2025 Asia programme.
Viking Tonle will operate the 15-day Magnificent Mekong itinerary which combines hotel stays in Hanoi, Siem Reap and Ho Chi Minh City with an eight-day Mekong River sailing.
The ship is currently under construction and is scheduled to enter service in October 2025.
The sister ship to Viking Saigon, Viking Tonle will accommodate up to 80 passenger in 40 staterooms.
On sale now, Viking is offering a £1,000 saving on all 2025 river cruises booked by December 31.
Chairman Torstein Hagen said: “The rich history and culture of Vietnam and Cambodia have always made the Mekong River a fascinating destination for our guests.
“With the addition of an identical sister ship in 2025, we look forward to introducing even more curious travellers to the treasures of this fantastic region in the years to come.”
