HIDDEN away up little known Raydale, a side dale of Wensleydale, is the beautiful lake of Semerwater. The second largest natural lake in the Yorkshire Dales (after Malham Tarn), it is used for both recreational purposes and as a well managed wildlife preserve.

Semerwater is only one-and-a-half miles from the pretty village of Bainbridge.

There is limited parking down the steep hill from Countersett, which makes a good place to start the circuit. The parking is next to a small beach, a lovely spot which serves as a launching place for the boats.

Opposite the car park are some steps leading to a bench and noticeboard where JMW Turner was meant to have painted Semerwater. The walk heads along the road to Low Blean Farm and the path that heads due south from here towards Stalling Busk. The path winds its way through Semerwater Nature Reserve. Oyster catchers, snipe and curlew are just some of the birds you may see whilst the open water supports the unusual yellow water lily.

The only other (similar sized) natural lake in the Yorkshire Dales is Malham Tarn and that has been artificially raised, whilst Semerwater was formed naturally at the end of the last ice age when fluvial deposits filled the outflow creating the lake. Be aware though, that after heavy rains this section of the walk can become very wet and the lake rises surprisingly quickly.

The path continues beyond the southern end of Semerwater until it reaches an old ruined chapel (built in 1772) and graveyard. Take the left hand path here which climbs into the little hamlet of Stalling Busk. A pretty church, St Matthew's, lies in its centre. This one in much better condition.

Stalling Busk marks the end of the road in the valley (which has run along 100 metres above the path).

From the church head west down a steep track towards Crooks Beck (one of the two rivers which feeds Semerwater), two footbridges leading towards Marsett.

Marsett is a collection of holiday cottages, two farms and a traditional phone box. It is in Marsett that there is a choice of route back to the start. The best route in bad weather is via the road which follows the north west shores of Semerwater. In good weather take the steep climb up the hillside to the shoulder of Wether Hill.

To find the path cross the bridge in Marsett then take the farm track west. After 200 metres, and before it becomes steep, take the footpath to your right for a short, sharp climb.

The reward for the steep climb are wonderful views across Raydale to the distinctive, flat-topped peak of Addleborough. Semerwater is revealed in all its glory, nestling, tear drop shaped, in the valley bottom.

The path reaches a bridleway on the broad moorland ridge. Turn right and follow this for one mile to the quiet road above Countersett. From Countersett drop down the road to your car.
