Llyn Brenig is a beautiful reservoir and is one of the largest inland areas of water in Wales. It has a perimeter of 9.5 miles and is surrounded by forest. The reservoir was built between 1973 and 1976 and helps to regulate the water supply to the river Dee.
There are lots of walks around the reservoir and the forest with lots of wildlife, get there early can you can see deer. There are also a number of cycle paths, so there is really something for everyone.
There is a very nice clean cafe that overlooks the reservoir that serves very good reasonable priced food.
