Walking Tours -- From July to September a daily guided tour of the city center, in English (and French), departs at 2pm from the tourist office; the cost is 5€ ($6.25) for adults and 2.50€ ($3.15) for accompanied children under 12. The tourist office can also arrange for a qualified guide to accompany you on private walking tours around the city at a set rate of 50€ ($63) for the first 2 hours and 25€ ($31) for each additional hour. There are also clearly marked self-guided walks, with brochures available from the tourist office.
By Boat -- Do take a cruise around Antwerp's awesome harbor, which handles 16,000 ships and 100 million tons of cargo a year. Most departures are from the Steen waterfront on the Scheldt. Flandria Line (tel. 03/231-31-00) runs a 2 1/2-hour harbor cruise for 13€ ($16) for adults and 7€ ($8.75) for children. In July and August there's a delightful harbor dinner cruise from 8 to 10:30pm, for 50€ ($63) for adults and 30€ ($38) for children. A 50-minute excursion on the river is less interesting, but still worthwhile, with half-hourly departures during summer months, costing 7€ ($8.75) for adults and 4€ ($5) for children.
By Bus -- The Antwerp Diamond Bus is a double-decker bus that tours the city's main tourist areas and sights on a regular circuit. You can hop on and hop off at various points on the tour. Tickets, valid for 24 hours, are 10€ ($13) for adults, 9€ ($11) for seniors and students, and 5€ ($6.25) for children.
