Wynlass Beck is short last flowing stream, becoming a waterfall and then flowing into Lake Windermere. Access is very easy with a short walk from a National Trust lay-by at Rayrigg on the A592. The lay-by is on the left with free parking for about 6 cars.
Continue down the path and reach a secluded spot on the shores of Lake Windermere. See Rayrigg Wyke entry.
There is a no actual address but if heading north from Kendal on the A591, turn left at Cooks House Roundabout for A592, towards Bowness and look out for the lay-by and National Trust sign on the left.
