Flinders Chase trails & lookouts

Guide updated 12 Sept 2026 · grades and open status change — verify parks.sa.gov.au

Start with a clear boardwalk icons vs remote walk decision. Remarkable Rocks + Admirals Arch covers most first visits. Distances, grades and times below are planning ranges — always confirm on parks.sa.gov.au and park alerts. Weather, closures and stair status change.

Decide before you lace up

Easy icons: Remarkable Rocks boardwalk, Admirals Arch (final steps), Platypus Waterholes, Cape du Couedic loop.
Moderate remote: Ravine Hike and Cape Borda’s longer cart track — often 4WD or a dedicated drive.
Hard multi-day: Kangaroo Island Wilderness Trail — booked, capped, Grade 4, water carry.

Stacking two hard walks plus the postcard lookout is the classic first-visit failure mode. Pick the table row that matches energy, then open the full trail guide for getting-there detail.

Quick comparison (planning only)

Walk / lookout	Effort	Time	Best for
Rocks + Arch	easy	Half day typical including drives; 30–60 min at each stop	First-timers, photography, families, mixed-ability groups

KIWT	hard	5 days typical; daily 10–17 km / 3.5–6.5 hours	Fit, booked multi-day walkers
Cape du Couedic loop	easy	Around 40 minutes	Adding cliff context after the arch without a half-day commitment
Ravine Hike	moderate	Around 3 hours	Experienced walkers with 4WD access to the trailhead
Cape Borda	moderate	1–4 hours depending on which walk you choose	Second-day contrast, lighthouse precinct, fit walkers wanting a steeper short hike

Easy

Rocks + Arch

easy

The signature Flinders Chase day: granite and lichen at Remarkable Rocks, then Admirals Arch, fur seals and Cape du Couedic on a sealed 2WD road. Wind, freak waves and midday coaches are the real limiters — not distance.

Grade: Easy boardwalks (final arch steps)
Time: Half day typical including drives; 30–60 min at each stop
Distance: Short boardwalks at each site (~1 km rocks circuit; ~800 m–1 km return at the arch)

Platypus Waterholes

easy

The best longer day walk from the Flinders Chase Visitor Centre: regenerating woodland, Black Swamp and Rocky River viewing platforms. Dawn and dusk give the best platypus odds. Rebuilt after the 2019–20 fires.

Grade: Easy / Grade 1–2 (some accessible sections)
Time: Around 2 hours
Distance: Official park page: 4.5 km / about 2 hours from the visitor centre

Cape du Couedic loop

easy

Short coastal loop at Cape du Couedic with interpretive signs, lighthouse precinct views and Southern Ocean cliffs. Best as an add-on after Admirals Arch, not a replacement for the arch boardwalk.

Grade: Short coastal loop (confirm official grade)
Time: Around 40 minutes
Distance: About 2 km loop

Moderate

Ravine Hike

moderate

Valley walk in Ravine des Casoars Wilderness Protection Area from a 4WD-recommended trailhead down to a remote beach. Not a 2WD icon-day add-on.

Grade: Longer remote valley walk (confirm official grade)
Time: Around 3 hours
Distance: About 7 km

Cape Borda

moderate

Northwest lightstation day: self-guided Cape Borda (included in park entry) plus either the steep 1 km Harvey’s Return hike or the longer Return Road cart track. Different ocean aspect to the southern icons.

Grade: Short steep hike + optional 9 km cart track
Time: 1–4 hours depending on which walk you choose
Distance: Harvey’s Return ~1 km / 30 min; Return Road Hike ~9 km / 3 hrs

View guide →

Hard

KIWT

hard

A capped, bookable 5-day trek from the Flinders Chase Visitor Centre to Kelly Hill Caves. Separate fee from day entry. Remote coast and regenerating interior. Limited bail-outs — treat it as a committed expedition.

Grade: Grade 4 — long, rough, steep sections, limited signage
Time: 5 days typical; daily 10–17 km / 3.5–6.5 hours
Distance: Official KIWT pages: 66 km over 5 days (Class 4)

Trail FAQs

Tap a question to expand the answer.

What is the best first walk in Flinders Chase?

Most first-timers do the Remarkable Rocks and Admirals Arch boardwalks on the sealed 2WD road, then add Platypus Waterholes only if energy and daylight remain. Ravine, West Bay and KIWT are not first-day upgrades. Always verify status with parks.sa.gov.au.

How hard are the walks?

The icon boardwalks are easy (arch has steep final steps). Platypus Waterholes is an easy two-hour walk. Ravine and Cape Borda’s longer options are moderate and often need 4WD access. KIWT is Grade 4 over five booked days.

Can I add Ravine or KIWT onto the icon day?

Usually a bad first-visit plan. Icons plus platypus already fill a ferry day. KIWT is a separate booked product. Ravine needs 4WD access and a dedicated half-day.

Are the icon boardwalks accessible?

Remarkable Rocks is a rebuilt Grade 1 boardwalk. Admirals Arch is mostly accessible with a steep final section of steps. Confirm live accessibility notes on parks.sa.gov.au if anyone in the group needs step-free access.

Do I need 4WD for any of these walks?

Not for Remarkable Rocks, Admirals Arch, Platypus Waterholes or the Cape du Couedic loop. Ravine trailhead and West Bay / Harvey’s Return access recommend or require 4WD and can close after rain. Check the visitor centre before you leave sealed road.
