This is a popular location for people wanting to walk or cycle. There is a good walkway right around the lake with no hills.
There are lots of opportunities for scenic shots of the water, and there seems to always be a lot of swans and ducks around. The swans don't seem worried by people and they let you get close. This is a good place for an afternoon walk with your camera.
On the southern edge there is a kids playground.
There is a reasonable amount of parking on the southern side near the shops and restaurants.
