Most rafting in Wales is just outside of Snowdonia National Park on the Afon Tryweryn River. Rapids range from Class II to Class IV, depending on the section of river.
Afon Tryweryn River Rafting Trips (Class II-IV):
A dam-controlled run with three creatively-named sections: The Upper, Middle, and Lower.
Dee River Rafting Trips (Class III):
Water is only released on the Dee River a few days each year, however, when it runs, the river has some fun rapids.
