The Scenic Eclipse will welcome three expert travellers onboard next February, as part of a 27-day cruise to Antarctica.

Sir Ranulph Fiennes will join guests in Buenos Aires for an exclusive talk and dinner, while mountaineer Sir Chris Bonington – the first British climber to ascend the Vinson Massif – will be present throughout the voyage, including for a walk and visit to Sir Ernest Shackleton’s grave.

Ben Osborne, an award-winning photographer with 30 years’ experience, will help guests document their journey during an in-depth photographer masterclass.

Fiennes, who completed the first unsupported crossing of Antarctica, said: “I have been privileged to explore Antarctica on several occasions and am delighted to share my experiences during this tour of a lifetime.”

Departing 26 February 2019, prices start from £21,395pp, based on two people sharing and subject to availability.

All-inclusive highlights include a 21-night five-star cruise on board the Scenic Eclipse; four-night luxury hotel stay in Buenos Aires with breakfast; all on-board complimentary fine dining and beverages; all onshore excursions, and a dedicated on board Discovery Team.

The Scenic Eclipse, the world’s first discovery yacht and the first ocean cruise ship from Scenic, will launch in January 2019.
