It's best to reach Jervis Bay via Huskisson, 24km (15 miles) southeast of Nowra on the Princes Highway. 16km (10 miles) south of Nowra, turn left onto the Jervis Bay Road to Huskisson. The entrance to Booderee National Park -- formally named Jervis Bay National Park -- is just after Huskisson. It's about a 3-hour drive from Sydney. You'll probably need at least 2 days to get to know the area. Watch for black cockatoos.
Australian Pacific Tours (tel. 02/9247 7222; fax 02/9247 2052; www.aptours.com.au) runs a dolphin-watching cruise to Jervis Bay from Sydney every day between early October and mid-April, and Monday and Thursday in winter. The 12-hour trip -- 7 hours of which are on the coach -- includes a visit to the Kiama blowhole, a 3-hour luncheon cruise looking for bottlenose dolphins, and a stop on the way back at Fitzroy Falls in the Southern Highlands. The trip costs A$117 for adults and A$109 for children.
