Natural Bridge and Castle Cove

Natural Bridge and Castle Cove are a paired coastal lookout stop in Kalbarri National Park. A short sealed path leads to two cliff-top views: Natural Bridge's wave-cut arch and Castle Cove's broad sweep of ocean and red-banded cliffs. I'd stop for both; they're close together but show different sides of this stretch of coast.

The Natural Bridge enclosure gives you the defining view of the arch above the surf. From Castle Cove, look toward Island Rock against the Indian Ocean. If you're taking photos, the arch is the close subject at Natural Bridge, while Castle Cove gives you a wider coast-and-sea frame.

This can be a quick stop, or the start of a longer coastal walk. The sealed boardwalk continues north toward Island Rock, a separate sea stack, and the longer Bigurda Trail reaches Natural Bridge from Eagle Gorge. Do both lookouts first, then carry on only if you want more walking.

The cliffs are Tumblagooda Sandstone, with the red bands Kalbarri is known for. Waves keep breaking into the rock and widening its fractures; Natural Bridge is one striking result of that slow coastal erosion.

Migrating whales may be visible from the cliffs between June and November, though a sighting is never guaranteed. Binoculars help when they pass offshore.
