The tour and river cruise operator is set to run more 100 group journeys this year, across 12 itineraries, from March through December.

The new itineraries include a five-day Northumbrian Coast, Durham and Lindisfarne tour, which features guided tours of Alnwick Castle and Durham Cathedral, from £849pp.

A five-day Edinburgh, St Andrews and the Royal Yacht Britannia tour includes a guided tour of Edinburgh and a visit to St Andrews for £599pp.

Both itineraries have five departures running from May to October.

Joanne Lynn, head of European product at Riviera Travel, said the new itineraries have been added "to give even more choice and variety" as interest "shows no sign of slowing down".

"We have been thrilled with the positive feedback we have received, from both the trade and guests, for all of our tour itineraries following their introduction last year," she added.

"With a wealth of stunning sights and scenery to explore, our tours offer a captivating experience for guests wishing to holiday closer to home."
