youtube has a bunch of Globe Trekker videos. You might find it there.

Was the visitor male or female?

Was it on PBS or some other channel?

Oops, maybe I found it. Is this is it? From Traditional Sports of La Palmas Gran Canaria:

El Salto del Pastor (The Shepherd´s Leap)

El salto del pastor or the shepherd s leap is a practical game, born from a culture that saw the need to develop a certain skill - the skill to leap across mountains and be nimble as a little boy shepherd. This need was inevitable, what with Gran Canaria s unusual mountain landscape of difficult terrain, natural obstacles, large ravines, steep rocks and treacherous cliffs.

Because of this, the natives had to develop the skill and technique of crossing over through the use of a long wooden pole which they called a garrote. This wooden pole has a metal point fitted at its tip which is known as the regatón. With the aid of this pole, it made it easier for them to traverse across hills and steep rocks, as well as ravines, trenches, and slopes.

To develop this skill, the mechanics of the game then is to place the regatón upon the earth where one is standing, after which one jumps and slides down the pole to navigate a steep drop, repeating the leap and slide movement as many times as is necessary to reach the bottom of the ravine.
Aside from this test of mobility in the ravines, the garrote is also used elsewhere. This would include climbing up and jumping over walls, fast descents down steep rocks, calculated leaps, acrobatic leaps and leaps of enumerable styles.
