The park contains the Sugarloaf, a distinctive conical geological formation created by Permian glacial processes.
Over 1,700 Indigenous artifacts have been cataloged in the park, representing one of the most significant archaeological sites in the region.
The boardwalk covers a landscape that was once covered by ice sheets during the Permian period, roughly 280 million years ago.
The park holds a site of international geological significance known as the Hallett Cove Glacial Pavement.
It is a popular location for observing migrating whales during the winter months.
Hallett Cove Boardwalk is a coastal walking trail located within the Hallett Cove Conservation Park, featuring significant geological formations and archaeological sites. The trail spans approximately 2 kilometers, connecting the Hallett Cove beach area to the clifftops at the southern end. The park preserves evidence of the Permian glaciation, including glacial striations and erratics visible in the sandstone rock faces. Aboriginal archaeological sites dating back over 50,000 years are located throughout the area, including ancient stone tool manufacturing workshops. The boardwalk structure is designed to protect fragile cliff vegetation and prevent soil erosion. Visitors can view various coastal scrub plants and native wildlife, including blue-tongue lizards and occasional echidnas. The site is a protected conservation zone, requiring strict adherence to remain on marked trails to safeguard the unique geological features. The trail features several steep sections with stairs that provide panoramic views of the Gulf St Vincent.
The elevated viewing platform overlooking the Sugarloaf formation provides the most iconic perspective of the geology.
Wear sturdy walking shoes with good grip, as the terrain can be uneven and the stair sections are steep.
Carry plenty of water and sun protection, as there is limited shade along the exposed cliff-top sections.
Start your walk from the southern end if you prefer to tackle the most significant elevation changes early in your visit.
Do not attempt to walk on the beach rocks or climb the cliff faces, as these are protected zones and prone to instability.
Stay strictly on the marked boardwalk and paths to prevent damage to the geological pavement and erosion of the sensitive cliff face.
