Fell Foot Park is a great, family friendly location at the southern end of Windermere. You will find a magnificent view up the lake to the mountains of the central lakes. The walking is easy and you can hire a rowing boat at the far end of the park next to the boathouse café. There is also an adventure park for children. It is a great place to have a picnic.
Fell Foot is 20 minutes away from Lothlorien.
