Trecastle-Tirabad is an asphalted military road located in Powys, Wales, on the edge of the Brecon Beacons National Park, one of three national parks in the country.
This superb road links the villages of Trecastle and Tirabad. It’s 8.4 miles long and the road doesn’t seem to have a name, although on a map it crosses Mynydd Eppynt and Mynydd Bwlch-Yr-Groes, a small range of hills to the north of the Brecon Beacons. It is a singletrack road that runs through Sennybridge army training area, and is open to the public, except for Army exercises. The area is used for 350 days per year for many different aspects of military training, such as artillery testing, rifle ranges, survival situations and war zone simulation. Each time you drive this road, you can hear gunfire and see soldiers hiding in bushes. There can be quite a lot of military traffic on it.
The surface of the road is asphalted. It has numerous blind turns and blind summits, with passing areas. The road has stunning views, and is quite exposed to the weather, reaching 414 metres (1,358ft) above the sea level. The surface is in very good condition, probably because it’s looked after by the army. It is highly recommended for any type of vehicle. Along the way there is evidence of the communities that lives here for generations and made a living from sheep farming in this exposed and isolated place.
