It has amazing views well worth a stop.

Great views from the bridge at the western end of Llyn Padarn. Look across the lake at the old Dinorwig slate mining and the Electric Mountain. To the right you can see over Llanberis and up onto Snowdon.

Found this lovely back road behind the Llyn Cwellyn with great views of the Arenig Hills. Highly recommend this road rather than using the main road around the lake.
