For Alessandra Ambrosio, even a simple nature walk is enough to cause a few craned necks.

The 34-year-old Brazlian beauty had that supermodel poise as she hit up the rustic Los Liones Canyon Trail in Los Angeles on Wednesday with her longtime fiance Jamie Mazur.

Alessandra wasn't on the runway but she was certainly a marvel in a short cropped athletic bra that displayed her remarkably toned abdomen and slender waistline.

She paired the small top with black leggings and black trainers with green and grey socks, all of which got a little dusty from the gravelly path.

Alessandra arrived wearing her cosy, body-swamping jacket but later tied it around her waist when the day grew warm.

A pair of mirrored aviator shades screened out the harshest rays of the sun while her straight brown hair was pulled back from her face.

Alessandra sported her usual bronzed tan and clutched an eco-friendly water bottle to stay hydrated during her hike.

Meanwhile, businessman Jamie was considerably dressed down too in navy cuffed jeans and a grey-blue T-shirt.

Jamie's athletic shoes matched Alessandra's in that they were also covered by the trailblazing dust.

The couple appeared to be enjoying some alone time without their two children in tow.

Alessandra and Jamie, who got engaged in 2008 but have yet to set the wedding date, are parents to daughter Anja, seven, and son Noah, who turns four next month.

In December of last year, Alessandra told Extra: 'When I do the wedding it's going to be very special, so I want to take time for that.'

That hasn't stopped the couple from embarking on some other business together.

Alessandra's fiance of eight years launched the Hanes Perfect Tee campaign for his denim company Re/Done, which stars the Victoria's Secret 'angel.'
