Admirals Arch: Where Seals Rule the Sea and Granite Meets Sky
A short boardwalk leads to a dramatic coastal grotto where seals and sea meet—easy to reach, hard to forget.
You arrive at the western edge of Kangaroo Island when the land finally stops trying to be anything but raw. Wind has a habit of speaking here; it tugs at your jacket and teases salt from the Southern Ocean. From the clifftop carpark a tidy boardwalk unfurls—timber and steel bolted into granite—descending in a few confident steps toward a natural doorway carved by relentless waves. Through that doorway, Admirals Arch frames a horizon that seems older than the map. Below, long‑nosed fur seals slip in and out of surf as if they own the tide.
Trail Wisdom
Use the boardwalk
Stick to the established boardwalks and viewing platforms—they protect fragile cliffs and keep you at the safe distance the seals need.
Bring binoculars
A pair of 8x binoculars reveals seal pups, snags of kelp, and seabird activity without disturbing animals.
Watch the weather
Winds can be strong on the west end; a windproof shell and secure hat will keep you comfortable during photography sessions.
Combine nearby sights
Plan to visit Remarkable Rocks and the Cape du Couedic lighthouse the same trip to make the drive out worthwhile.

Common Questions
How long does it take to visit Admirals Arch?
The boardwalk and viewing platform can be experienced in 20–45 minutes; combine with Remarkable Rocks and Cape du Couedic for a half‑day.
Is Admirals Arch wheelchair accessible?
There are steps to the main viewing platform so full wheelchair access is limited; the carpark and some lookouts near the lighthouse are easier to reach.
Can I get close to the seals?
No—observe from the platform and keep to the boardwalk; seals are wild and protected, and close approaches stress them and can be dangerous.
Are there guided tours that include Admirals Arch?
Yes—options range from full‑day group tours from Kingscote to small‑group and private luxury tours that include Admirals Arch, Remarkable Rocks, and wildlife spots.
What’s the best time of day for photography?
Early morning and late afternoon offer softer light and calmer visitor numbers; for dramatic surf, stormy afternoons are best.
Are dogs allowed?
Pets are not permitted in Flinders Chase National Park; the area is protected and wildlife‑sensitive.
What to Pack
Windproof jacket, binoculars, water bottle, sturdy shoes — for shelter from spray, close wildlife viewing, hydration, and secure footing on boardwalks.
