Happisburgh Light House play park is a real favourite with the kids and I, discovered with thanks to Nanny and Grandad! I think it should win the award for the playground with the best view (at least in the East of England category!).
The playground is set directly in front of the lighthouse with views of the beach and sea. There is good parking, if a little pricey should you wish to stay all day. Please see my photo for tariffs but also check the website as they may be updated from time-to-time. The toilets are excellent and there is a picnic area with benches just to one side of the car park.
I would just say from experience there is a slope going down to access the beach off the picnic area and this is a little prone to the elements so always best to make sure little ones are well supervised if you are picnic-ing as my two were drawn to this slope like moths! The beach is absolutely gorgeous, full of rock pools and beautiful sand for building with.
A day can easily be spent there in the summer for no more cost than the parking and even during the rest of the year this is a real staple for an hour or so on a fine day.
