Our hotel is just down the road from here, and in a 2 week holiday we want almost every day. Entertainments include:
The famous naval battle
Feeding ducks any time of day
A 40 minute walk seeing some of the best trees in the UK.
A walk up to the top of the island.
A row around the lake.
Romantic walk around the park at night, when the lights illuminate the lake.
Or, you could just have an ice cream, and admire the view!
