If you're feeling energetic, or just looking to work off an excess of fondue dipping, Interlaken offers many opportunities for sports -- sailing, windsurfing, rowing, fishing, golf, tennis, mountain trekking, and glider flying. There's also a swimming pool in town. More information is available at the tourist office.
Golf -- You can play at the Interlaken-Unterseen course (tel. 033/823-60-16; www.interlakengolf.ch) from April to October. The cost is 100F Monday to Friday and 120F Saturday and Sunday. With a visitor's card, the cost is reduced to 90F on weekdays and 110F on weekends.
Horseback Riding -- There are several bridle paths between Lake Thun and Lake Brienz. The Voegeli Riding School, Scheidgasse 66, in Unterseen (tel. 033/822-74-16; www.reitschulevoegeli.ch), offers 1-hour riding lessons for 55F.
Swimming -- There's a public indoor pool and a public open-air pool, Bödeli (tel. 033/827-90-90; www.boedelibad.ch), behind the Kursaal. The indoor pool has a sauna and a solarium as well as a fitness room. This pool is open year-round Monday 2 to 9pm, Tuesday to Friday 9am to 9:45pm, and Saturday and Sunday 9am to 6pm. Entrance is 9F for adults, 5F for children 6 to 16, and free for children 5 and under. The outdoor pool, with its changing cabins and 9.9m (32-ft.) diving board, is open mid-May through September daily from 9am to 7pm. Keep in mind, though, that even July and August might be too chilly for you. Entrance is 6.60F for adults and 3.50F for children.
Tennis -- Use of a court at the Höhematte costs 25F per hour for visitors. If you're alone and willing to be matched up with another person, it will cost you half the court fee. For reservations, phone tel. 033/822-14-72. The courts are open from mid-April to mid-October daily from 8am to 8 or 9pm.
