The Odense Tourist Bureau offers a 2-hour walking tour conducted in July and August, every Tuesday, Wednesday, and Thursday at 11am, from a meeting place behind its office. Covering the town's major sites, it costs 50DKK ($8.50/£4.50) adults and 25DKK ($4.25/£2.25) children 10 to 15; free for children under 10. Reservations are recommended.
Also at the tourist office, you can get information about the Hans Christian Andersen plays, which are presented every year mid-July to mid-August. The plays are given on an outdoor stage in the Funen Village, where members of the audience sit on blankets on the grass (if it's dry) or stand (if it's raining or if the ground is wet). Even if you don't understand Danish, there's lots of entertainment value in the visuals. Plays begin every day at 4pm, last around 90 minutes, cost 70DKK ($12/£6.30) adults and 45DKK ($7.65/£4.05) children 10 to 15, and are usually mobbed with H. C. Andersen fans.
Less than a kilometer (1/2 mile) west of the city center is Superbowl, Grøneløkkenvej (tel. 70-11-11-55; bus: 91 or 92), a complex of amusements and diversions that are entirely devoted to popular American culture. It incorporates facilities for indoor go-cart racing, an indoor version of American-style miniature golf, several bowling alleys, and a small-scale collection of rides and games inspired by the theme parks of Florida. Each individual attraction within the park maintains its own hours and entrance policies, but the best way to appreciate this site's activities is to head here anytime daily between 10am and 6pm, when for an all-inclusive fee of 80DKK ($14/£7.20), you'll have unlimited access to all of them.
