The new programme includes short sailings which offer an "affordable introduction" to river cruising, longer trips exploring the Rhine and Danube and a selection of festive breaks.
"Early-bird" pricing means a three-night Dutch Waterways and Keukenhof Gardens cruise aboard Arena departing 14 or 21 April 2023 costs £495pp, based on two sharing a main deck cabin on full-board basis.
The sailing includes an opportunity to explore Zaandam, on the banks of the Zaan river, and a full-day excursion to the Keukenhof Gardens.
A new 12-day Salzburg and Historic Gems along the Rhine sailing departs 2 July 2023 and costs £1,649pp based on two sharing a main deck cabin on full-board basis. The cruise takes in a series of historic riverside towns and cities on the Rhine and Main rivers, as well as the Main-Danube canal and upper reaches of the Danube.
Arena managing director Steve Goodenough said the line has seen "greater confidence" from clients now pandemic-induced travel restrictions have largely been lifted.
"Unfortunately, due to ongoing increases in operating costs, it is inevitable that prices will have to rise in the near future so we would recommend that agents encourage their clients to book early wherever possible to secure the best prices," he added.
