This is another national park that really needs a 4WD to explore the best of it. Highlights include the massive wind-sculpted sand dunes, pounding surf, and limestone cliffs of Memory Cove, a pretty beach protected by two headlands that was named by explorer Matthew Flinders as a reminder of a tragic accident that took the lives of his eight crewmen in 1802. Take a walk up Stamford Hill for spectacular views of Boston Bay, Port Lincoln, and the park. A monument commemorating Matthew Flinders is at the top. There is also a good 2-hour walk around the tip of the Donington Peninsula (one of the few places in the park you can get to in a conventional two-wheel-drive vehicle; you can stay at historic Donington Cottage; tel. 08/8683 3544), with great views of offshore islands, granite outcrops, and sandy beaches. You can often see Australian sea lions and New Zealand fur seals on Donington Island near the lighthouse.
