1. Norway: eight nights from £1,099pp
With a proud Norwegian heritage stretching back to the mid-19th century, family-owned Fred Olsen Cruise Lines lives up to its formidable reputation as the Fjords Specialist.
And as the dramatic spectacle is best enjoyed from the water, the smaller dimensions of its fleet of four ships means they can sail in closer to these natural wonders.
The deal: Elegant Boudicca, capable of carrying up to 880 passengers, leaves from Liverpool on August 29 for an eight-night foray into the Norwegian fjords.
Among the ports of call will be the charming village of Olden, the historic city of Bergen, and Flåm, renowned for its scenic railway. Prices from £1,099pp on the Fred Olsen website here.
2. Canada: 28 nights from £1,999pp
Join the festivities as the country marks its 150th anniversary this year.
Fittingly, CMV's classic ocean liner Marco Polo (pictured, top) will be making the voyage from Liverpool – the vessel previously known as the Alexandr Pushkin sailed from the Mersey port carrying emigrating Brits to Canada over 50 years ago.
And the cruise's September 1 departure means you'll arrive in time to see Eastern Canada in its glorious autumn colours.
