Indonesia is one of the most diverse nations, culturally and ecologically, on Earth. Its thousands of islands, each with its own unique natural elements, make it an ideal place for a nature- or culture-themed cruise. Several companies offer trips to the more far-flung of the archipelago’s islands on classic cruise ships that resemble the wind-powered schooners that once sailed these waters, carrying spices and other goods. Other companies, such as SeaTrek Sailing Adventures, offer excursions to places like Bali, Lombok and Komodo (home of the famous Komodo dragons). SeaTrek even has a history-themed trip that follows the route of naturalist Alfred Wallace, who was one of the first people to raise the issue of conservation in Indonesia.
