The Glenelg River flows through the Lower Glenelg National Park, filling a spectacular drowned canyon between limestone cliffs that are 50m high.
Massive and mobile sand dunes and freshwater swamps are found along the Discovery Bay shoreline. Princess Margaret Rose Cave is an extensive limestone cave beside the Glenelg River. At Cape Bridgewater there is an Australian fur seal colony and blowholes.
Best time to visit
Late winter and spring are the best times for wildflowers in the heathlands. Summer is great for camping and canoeing on the Glenelg River and in the lakes, but stay out of the forest during times of total fire ban. Winter and early spring are good for whale watching from the cliff tops at Cape Bridgewater, where you can also see the fur seal colony and blowholes.
What to do
Visit Princess Margaret Rose Cave from a tour boat trip out of Nelson or drive there via Donovans in South Australia.
Car touring throughout the area provides access to many pleasant camping and picnicking sites. Canoeing is popular along the Glenelg River, with options for single and multi-day trips between bush campsites.
There are many short walks in both parks that include both river and coastal scenery. The heathlands are great places for wildflowers during spring. Walk the cliff tops from Bridgewater Bay to Cape Bridgewater to view the fur seals and take in views of the highest coastal cliffs in Victoria. The multi-day Great South West Walk passes through both parks and also the nearby Cobboboonee National Park and Cape Nelson State Park.
