These twin peaks of limestone and basalt dominate West and North West Belfast's skyline. A BBC Transmitter masts sits atop Divis whose Irish name translates as black back. Thanks to a transfer in ownership in 2004 from the Ministry of Defence (who used it for army training and, allegedly, survelliance) to the National Trust, Belfast's highest peaks are now open to the public. The Trust has uncovered 2000 acres rich in biodiversity and archaeological interest, as well as constructing signs, paths and the Long Barn visitor centre. Walkers should be aware that this no Sunday stroll, though, and sudden changes in the weather can make conditions very treacherous. Ensure you come prepared- wear wellies and wet-weather gear and let someone know where you're heading. To get there take a Metro bus, walk or drive to the Upper Springfield Rd. entrance, then trek to the summit for amazing views stretching as far as Scotland on a clear day.
