Hi, we are an Australian family of four coming to visit in January. We are planning on hiring a car from Heathrow and driving up via Stonehenge and Bath and returning via the Cotswolds and Oxford. We are planning on getting an apartment in Swansea for a week and making some day trips by car. I am interested in going to the Brecon Beacons national parks. I am interesting in hearing your opinions on doing this given the likey weather at that time of year. Please keep in mind that we are not use to snow or icey conditions.
