The varied landscape of Wales attracts tourism. There are three national parks: the Brecon Beacons National Park, the Snowdonia National Park and the Pembrokeshire Coast National Park. Popular activities in the national parks include hill walking, hiking, canoeing, mountain biking, kayaking and climbing. Wales is also becoming increasingly popular for 'extreme' sports, such as surfing, hang gliding and downhill cycling (in which Wales hosts the 'Dragon Downhill Series'). The terrain of Wales has also attracted the World Rally Championship (WRC). The Wales Rally GB is held annually. The 2005 Wales Rally GB saw the first WRC stage to be set indoors, at the Millennium Stadium. In Cardiff, the regenerated Cardiff Bay area is one of the most popular destinations.
