Softplays/playgrounds?

Hi, we have just moved to Folkestone and we are slowly settling in :). My little boy is 16 months and needs to move a lot to be happy :)! We live near the harbour and I am looking for places that are accessible by walk to go to with Noah for him to climb, play and run. We go to the beach every day but with the wind etc. I am looking for an alternative for some days where we could stay for an hour+. He used to be signed up to the little gym when we lived in London, so I wonder if there is something similar here? Classes or softplays, playgrounds that you’d recommend? Thank you so much! Hope to connect with you 🫶✨
