Amsterdam is Europe's ideal singles city, because it is not that difficult of a place to get to and to navigate for a person traveling alone. Plenty of solo travelers visit here every year -- you can think of Amsterdam as Europe's singles central. There are lots of hotels and restaurants in all price bands, and it's easy to meet other people around the bars and clubs, on canal-boat tours and bicycle tours, and in other ways. Companies that specialize in solo travel to Amsterdam are thin on the ground, though. One is the Singles Travel Company, 56 N. Santa Cruz Ave., Los Gatos, CA 95030 (tel. 888/286-8687 or 408/354-3871; www.singlestravelcompany.com), which takes in Amsterdam as a part of its European tour.
