South Africa.
My grandpa lived there so we started going regularly-ish to visit him but unfortunately he passed away. I haven't been back since but my parents went again this year.
His winter house was a couple of hours south of Durban & was literally 50m away from the beach in an apartment complex. You could hear the sea lapping the shore in bed at night. There was a trampoline, I used to hit a tennis ball against the garages and there were monkeys resident. Good childhood memories.
Would love to go back one day myself.
