For example, Seabourn offers guided bicycle excursions in Madeira, Sardinia, Sicily, Florence, Athens, Helsinki, around Stockholm's Royal Djurgaarden park and, in Denmark, at Skagen and on the island of Bornholm.

Guests are also offered chances to explore the French island of Corsica, the slopes of Sicily's Mt Etna, the Greek isle of Corfu and the vineyards and flower fields of Provence on mountain bikes.

For those seeking something even more strenuous, Seabourn offers excursions involving the popular European activity called "canyoning", in which participants swim, jump, climb, rappel and float down scenic river canyons, one located near Nice, France and another at the Alcantara Gorge on the island of Sicily.

A variety of guided walking tours are available in nearly 20 of the line's European ports of call, including cliff walks on the isle of Guernsey; walking the moors of Dartmoor from Plymouth, England; exploring the Art Nouveau section of Aalesund, Norway on foot; following Cezanne's footsteps from Nice, strolling Barcelona's Gothic Quarter, an "insider's" walking tour of Mykonos and volcano hiking on Santorini.

Some Adventure Collection excursions feature highly specialized activities, such as a sea-kayaking tour of the waters around Dubrovnik, sailing on the Turkish coast and a truffle-hunting expedition near Rovinj on Croatia's Dalmatian Coast.

Adventure Collection tours are offered in Europe along with Seabourn's award-winning Signature Series tours, which often feature privileged entry into museums and other attractions when they are closed to the general public, exclusive receptions with local dignitaries, or introduction to fascinating local features that are well-known to insiders, but remain off the typical tourist's itinerary.
