Ultra-luxury Silversea Cruises has opened the books on its World Cruise 2015.

This grandest of travel adventures will commence on January 5th, 2015, when the elegant, all-suite Silver Whisper is set to embark on a 115-day epic voyage, encircling the world and embracing the cultures of five continents, 30 countries and 50 unique destinations.

Departing Los Angeles with no more than 382 guests on board, Silver Whisper will sail the warm waters of the South Pacific to explore the idyllic isles of French Polynesia, then head west to the scenic wonders of Australia, and north to the marvels of the South China Sea.

From there, the journey continues to Vietnam, Thailand, Singapore, Malaysia, Sri Lanka and across the Indian Ocean to the glistening sands of the Seychelles.

Silver Whisper then traces a course to some of Africa’s most intriguing destinations, including Mombasa, Zanzibar, Cape Town, Walvis Bay and Dakar.

The voyage concludes with a leisurely Atlantic crossing to Fort Lauderdale, highlighted by stopovers in the sunny Caribbean islands of St. Lucia, St. Bart’s and Puerto Rico.

World Cruise 2015 offers travellers the opportunity to truly immerse themselves in local culture with late-night departures in eight ports, plus overnight calls in Papeete, Sydney, Fremantle, Hong Kong, Ho Chi Minh City, Bangkok, Singapore, Mombasa, and Cape Town.

“This exceptional voyage has been crafted to appeal to luxury travel’s most discerning clientele,” said Ellen Bettridge, Silversea’s president, Americas.

“Our World Cruise guests will visit the most exotic places and fascinating cultures on Earth - all while enjoying the pampering luxury of Silver Whisper.”

Silversea is offering guests the option to extend their World Cruise by adding a pre-cruise Panama Canal voyage from Fort Lauderdale to Los Angeles (17 days), or continue on board from Fort Lauderdale to New York (three days) or Southampton (15 days).
