There are parking areas on both sides the A486 adjacent to the lake. Walk through the gate and onto the footpath which soon bears right, following the lake shore. Cross the wooden bridge over the river and continue on the path towards the lake. Pass through the gate and continue on the footpath, next to the water. You will cross a small bridge over a pretty stream tumbling down the hillside and this is a nice spot to linger or to let your dogs paddle.
The path continues along the lake shore and there are several points where you or your dogs can access the water. You can take advantage of the many benches which feature on the trail if you would like to soak up the views or rest. Towards the far end of the lake, the footpath starts to turn away from the water and into open countryside.
You will arrive at a gate shortly before farm buildings where there is a warning to put dogs on leads as there may be livestock grazing. At this point you can decide to retrace your steps, continue to the road or walk to Llyn Gwynant.
