Silversea Expeditions delve into special interests, from birding to diving

For example, ornithology voyages give the chance to spot bald eagles in Alaska or see the blue-footed boobies of the Galápagos. Exceptional birding opportunities for casual enthusiasts and serious birdwatchers are available on Silver Explorer, Silver Galapagos and Silver Discoverer cruises.

Wellness themes are available on Silver Discoverer to destinations off the beaten path in Southeast Asia and the South Pacific. Specialists host a program of fitness training, including stretching, yoga and Pilates. Other highlights include daily lectures and cooking demonstrations focused on balanced nutrition. Plus, cruisers may book a complimentary spa massage.

On photography expedition voyages, passengers can participate in photo walks and attend shipboard lectures and workshops with a professional photographer. The photography focus is available on Silver Explorer and Silver Discoverer.

Diving opportunities are abundant in Indonesia, Micronesia, Melanesia and Polynesia in a SCUBA program presented by Silver Discoverer's on-board dive masters and expedition team.

And culinary expedition voyages aboard Silver Explorer offer an array of events on board and ashore.
