Africa's longest double zipline will open in the Sundays River Valley near Addo, located about 1 hrs from Port Elizabeth, on 01 September 2014. The zipline runs 60m over the Sundays River, which is known to South Africa's fastest-flowing river when in flood. With a lenth of about 500m the "double zipline" flies two riders over the river at up to 60 km/h depending on your weigh. An automatic breaking system stops your motion as you approach within 40m of the end of the zipline. A ride with the zipline costs R200/person (guides & equipment included; allow 1hrs). For more info about the zipline and all other adventures offered by "Adrenalin Addo", visit their website! Enjoy!
