It’s a National Trust for Scotland house and estate near Musselburgh, not far from the Forth shore between Joppa and the old harbour at Fisherrow. There’s a rather fine play area for small people, “Weehailes”, with well-placed picnic benches for mums, dads and grandparents… Sadly, the latter are just a bit too old for the play equipment (it does look fun!) – a walk through the estate to the shore and back will have to suffice for them…
