More ways to explore the area's outdoor wonders
You step off the Naiad onto sand that seems to reflect the sky and the ocean immediately reaches for your bootlaces. Dirk Hartog Island announces itself with surf, wind and an angled horizon; gulls wheel and a distant blowhole thumps like a slow drum. The day unfolds as a maritime handshake — a short boat transfer from Denham, then a string of shore-side discoveries.

Protect against sun and wind
The exposed beaches and boat deck intensify UV and wind — high SPF reef-safe sunscreen, a wide-brim hat and wind layer are essential.
Prepare for boat motion
If you’re prone to seasickness, take medication before boarding and choose forward seating on the Naiad for the smoothest ride.
Footwear for mixed terrain
Bring reef shoes or sturdy sandals for rocky intertidal zones and soft sand — avoid flip-flops for 4WD exits and rocky walks.
Respect wildlife and historic sites
Keep distance from seals, turtles and nesting birds; do not remove artefacts from the Inscription site.
