Open-air tourism is nothing new for Wales. Its nature parks have been popular destinations for decades for mountain biking and hiking enthusiasts. Snowdonia National Park, in the north of Wales, is the most popular. It contains the highest mountain in Wales, Snowdon, which is 1,085 metres high. Although you can reach the top by train, it has few similarities in comparison with the Alpes. Here and on the other 15 mountains that are over 900 metres high included in this park, there are lots of chances for swimming, rafting, abseiling, climbing and, of course, simply walking among the lakes and waterfalls.
