Police are offering travel advice to anyone considering heading to the Brecon Beacons this weekend.
An influx of visitors is expected for the Fan Dance event scheduled to take place on Saturday and Sunday, while visitor numbers are often high at the beginning of the year.
Roads policing officers will be patrolling the Storey Arms area, which is expected to be particularly busy, and people planning to visit the area are being asked by police to consider finding alternative parking spots and routes to Pen y Fan.
The winter and summer Fan Dance events are an opportunity for civilians to attempt the famous SAS selection marches on the Brecon Beacons.
Many walkers also take to the Brecon Beacons at this time of year.
Sergeant Owen Dillon, of the Roads Policing Unit, said: “I anticipate a very busy period on the local roads this weekend and particularly in the area of Storey Arms. In addition to the large number of visitors I expect to walk up Pen y Fan, the Fan Dance event is taking place, bringing extra parking to the area.
“There are a number of alternative places to park your vehicles if visiting the Brecon Beacons, which still have good routes to Pen y Fan. I would urge anyone planning on visiting to consider parking at locations including Cwm Gwydi or the Neuadd Valley. There is also a bus service available between Merthyr and Brecon which stops at Storey Arms.
“We will be continuing with police patrols of the Storey Arms area this weekend and will take action where it is required. Our priority is ensuring there are no obstructions on the A470 and that people observe the clearway and do not park on the road.
“We appreciate that the beautiful Brecon Beacons draw in thousands of walkers, and we encourage visitors to come and enjoy the region.
“We just ask that they do so safely, taking into consideration their own needs, that of other walkers, and other road users who also want to come and enjoy what Dyfed-Powys has to offer.”
