You'll find Llyn yr Adar's wild waters between the popular Cnicht, often cited as being the 'Welsh Matterhorn', and the less frequented Ysgafell Wen. The llyn is a useful navigational feature for those who've ascended Cnicht and are continuing to Moelwyns Mawr and Bach, or for those heading back to Croesor. It's also a great wild swimming spot and don't be surprised to see tents pitched by its shores either.

A beautiful and secluded lake in the Moelwynion region. The banks of the lake are a relatively popular wild-camping spot, and the lake is a perfect spot to cool off and have a breather.

Llyn Dinas is a large but shallow lake to the northeast of Beddgelert. The A498 road runs along its northern shore, while there are footpaths that explore its southern banks. Routes up Yr Wyddfa (Snowdon) from the mountain's southern side begin just to the northeast of the lake, including the Watkin Path, which is one of the most strenuous ways to the roof of Wales.

The village of Trawsfynydd, on the banks of the artificial llyn of the same name, is a great basecamp slap bang in the middle of Eryri (Snowdonia) National Park. The trails of the Coed y Brenin Forest Park are nearby, while the Rhinogydd provide hillwalking of the highest quality. There's bunkhouse accommodation at the Cross Foxes pub, which also serves great food. The village and lake are known for the nearby nuclear power station, which is no longer operational. Amazingly, at one time, the power it generated was enough to provide all of Wales' electricity needs.
