A charity wants more walkers to take to the Scottish hills before May is out.

Mountain Aid’s Corbetts4Courses challenge aims to see all 222 of the nation’s corbetts climbed during the month.

Proceeds from the charity event will be used to provide free navigation, winter skills and outdoor first aid training courses, along with free winter mountain safety lectures at venues across the country.

The charity also stages Skills for the Hills and Scottish Mountain Safety Days. These exhibition style events offer hill-goers a chance to meet and talk to agencies involved in the great outdoors in Scotland.

Corbetts4Courses involves walkers pledging to summit one of the Scottish peaks between 2,500ft and 2,999ft. Mountain Aid said many hills have already been climbed or committed to, but walkers still have a good number to ascend.

A spokesperson said: “After a cold start to the month, the good weather is bringing out the hillwalkers and, now just over halfway through the month, the pace is picking up with 80 hills already climbed or committed – but there are still plenty to choose from.”

Anyone taking part is asked to make a donation to the fund, with £10 suggested.

Walkers can post pictures of their summit venture on a Facebook page set up for the challenge.

Two online donations pages have also been created on PayPal and Virgin Money Giving.
