The North Sea's fair-to-middling waves make surfing fun for both the initiated and the uninitiated, who might prefer boogie boards. A wet suit is not an option but a necessity, unless you want to experience hypothermia. Rent surfboards and wet suits from Hart Surfshop, Vissershavenweg 55B (tel. 070/354-5583; www.hartbeach.nl), which runs a beach hut and surf school during the summer season. The oddly named Go Klap, Dr. Lelykade 44 (tel. 070/354-8679; www.goklap.nl), rents surfboards, other windsurfing gear, and sea kayaks. Windsurfers congregate at the Windsurfvereniging beach hut opposite the lighthouse. For windsurfing and kite-surfing lessons, in and out of season, contact instructor Harry Vogelezang (tel. 065/132-3547).
Head out from the harbor for a deep-sea fishing day trip aboard a converted trawler, operated by Rederij Groen, Dr. Lelykade 1D (tel. 070/355-3588; www.rederijgroen.nl).
Are you up for a plunge into the cold gray waters of the North Sea? Bungy Jump Center Scheveningen (tel. 070/345-3662; www.bungy.nl) can accommodate you, with a 60m (197-ft.) freefall from their jump point on Scheveningen Pier. Jump times (weather permitting) are May to June and September weekends from noon to 8pm, and July and August Wednesday to Sunday from noon to midnight.
A Great Theme Park -- For a theme park with rides galore -- roller coasters, carousels, treetop cable cars, and Europe's largest tropical water paradise, head for Duinrell, Duinrell 1 (tel. 070/515-5255; www.duinrell.com), at Wassenaar, 5km (3 miles) north of the Hague. Water activities include luge runs, the centrifugal Waterspin, and floating plastic frogs. In addition to the amusement park, covered tropical swimming pools are ideal for wet-weather days with kids. The park is open April to October daily from 10am to 5pm; the pool is open throughout the year. September to March, you can ski on an outdoor artificial ski slope. Admission is 23€ ($37), and free for children 3 and under. Bus no. 491 goes to the park from the Hague Centraal station and other points in the center city.
