Sleaford–Wanna dunes

A different park face

The southern side of Lincoln National Park is Southern Ocean, not Boston Bay granite. Parks SA describes massive wind-sculpted dunes and pounding surf. Ranger tips include the Sleaford–Wanna dune system and whale watching from Wanna and Lone Pine lookouts between May and October.

This is 4WD country. Follow red marker posts. Standard road rules apply. Do not drive off designated tracks. Getting bogged is common — Parks SA says so in plain language.

If you only have a sedan and a first Port Lincoln overnight, this is the wrong corner. Use Stamford Hill.

Western Sleaford entrance (VERIFY live)

Official park-page banner re-checked 13 Sep 2026 (dedicated alert last updated 10 March 2026 and still showing): a mobile sand dune has blocked the western (Sleaford) entrance/exit of the Sleaford–Wanna 4WD track and it is impassable. Use the main Proper Bay Road entrance to enter and exit.

Do not treat a 4WD blog, an old GPX file, or last year’s trip notes as current. If the live alert is gone tomorrow, still verify on parks.sa.gov.au before you commit to a west-gate plan.

Lookouts vs the 14 km hike

Wanna and Lone Pine lookouts are the accessible whale-watching pins May–October. Southern right whales are possible, not guaranteed. Stay legal distances. Lookouts, not a scramble down crumbling limestone.

Wanna Dunes to Sleaford Mere is a hard hike: 14.3 km, about 5 hours. Low mallee to a vantage, then exposed Southern Ocean beaches and limestone cliffs. Brian Clarke Hut at checkpoint 23 is a bushwalker shelter, not a booked cabin. Start from the car park just south of checkpoint 22.

Sand, tides, recovery

Deflate for sand. Carry a shovel and a compressor. Reinflate before sealed roads. Check tide times before beach sections. Stay on designated tracks — off-track driving damages habitat and is not a shortcut.

Beach fishing at Millers Hole and Salmon Hole is 4WD-only. Thorny Passage Marine Park sanctuary rules apply on the south coast: Sleaford Bay sanctuary (Wreck Beach to Wanna Lookout) allows shore-based recreational fishing only. Check PIRSA. We do not publish bag limits.

Fire, heat, comms

Park closed on Catastrophic Fire Danger; may close on Extreme. Wood / solid-fuel fires prohibited in fire danger season (usually 1 November–15 April). Bring water. None is supplied.

Coverage is patchy, especially low-lying. 000 needs reception. Emergency+ and Avenza. A PLB is a sensible remote-4WD note, not a park requirement.

Whale-season lookouts (May–October)

Parks SA: each year between May and October you may spot southern right whales off the Sleaford Bay coastline in Thorny Passage Marine Park. Most accessible spotting is from Wanna and Lone Pine lookouts. Bring optics, patience and a 4WD plan if the lookout roads need it.

Pick the next park face — do not stack Memory Cove, Wanna dunes and Stamford Hill because the first hour felt easy.

• Stamford HillSealed-road day visitor country: Stamford Hill (Flinders Monument), Surfleet Cove and granite Boston Bay. The honest first Lincoln National Park hour — not Memory Cove and not the Sleaford dunes.
• DoningtonPeninsula granite, lighthouse, white-sand September Beach and the Donington Loop. Sealed-road camping and one of the park’s better full-day shapes.
• Memory CoveLocked-gate wilderness bay: white sand, vegetated headlands, 15 vehicles a day. Book vehicle entry and camping, then collect a key from Port Lincoln VIC ($50 cash deposit on the official fees tab — VERIFY). 4WD required at times. Not a Stamford Hill lookout.
• Taylor’s LandingEastern Jussieu Peninsula: boat ramp, allocated campsites, secluded beaches and Investigator Trail junctions toward Pillie and MacLaren Point.
• Entrance / PillieThe front door: Proper Bay Road main entrance, Pillie Lake, Sleaford Mere links and inland mallee. Where sedan days start — and where dune parties must return while the Sleaford gate is blocked.
