Standing on the edge of one of the largest canyons on the earth and experiencing one of the most scenic landscapes in the world. After years and years of the Blyde River running by the Blyde River Canyon in South Africa's Mpumalanga province will leave you utterly spellbound. It is 2,600 feet deep and stretches 16 miles long, this dizzying chasm of towering cliff faces, cascading waterfalls, and marbled orange and green rock formations is simply out of this world.
