Watch: Sheep scales popular Wellington swing bridge

It carries a warning for anyone with vertigo, but that was no problem for sheep spotted using a swing bridge on a popular Wellington coastal walking track.

The 10-kilometre Paekakariki Escarpment Track is part of the Te Araroa trail, and runs from Paekakariki to Pukerua Bay. It runs high above State Highway 1 and the railway, reaching 220 metres above sea level with spectacular views.

Bryan Wilson was doing a trail run on the track when he said he met a "sheepish looking fella on the second bridge".

A video shows the sheep running across the high swing bridge before scrambling up a steep set of stairs.

"I had encountered another sheep earlier on the gravel track on a reasonably flat spot - [I] stopped for a bit, got closer and took a photo," he said.

"It ended up doing an about-turn and ran in front for about 50 metres, then u-turned up the hillside," said Mr Wilson.

He said it's not the first time he's seen sheep along the track.

"I think it's pretty cool to have them wandering around. As long as you don't do anything stupid to spook them, they'll sort themselves out."
