In pictures: Scotland's mountain highliners

A group of friends have taken the sport of highlining into some of Scotland's most stunning landscapes.

Inverness-based Owen Hope, 25, and Lizzie Wood, 26, along with Michael Ross, 30, who lives in Glasgow, all have backgrounds in climbing.

Highlining involves walking on a long piece of webbing anchored at two points high above a gap such as a gorge, while harnessed to a back-up safety line.

Last month, the friends rigged a highline over a gully between Sgurr Fiona and Lord Berkley's Seat, rocky features on the An Teallach ridge in the Highlands.

Mr Hope said: "Between the three of us we are in the mountains a lot and always coming across gaps that have nice anchors and are in cool places."

He added: "It's kind of fun if it is a bit difficult.

"Carrying three rucksacks with highline gear up to the top of An Teallach ridge was a bit of a suffer-fest, but good fun and a good way to stay healthy."

The group look for places with massive rocks attached to a mountain or cliff, and in other locations large trees, where line can be anchored.

As well as Scotland's mountains the group has rigged a highline across a bay to the south of Dunnottar Castle, near Stonehaven, and walked above a frozen lochan below Skye's Old Man of Storr.

Weather plays a major part in whether a highline goes ahead or not.

Owen said: "There is a sense of 'look we've come all this way we might as well rig something'.

"Naw - go home. The mountain is always going to be there again."
