We were at Ladram Bay this summer and this totally made the holiday for all of us. We could sit with a quiet drink or something to eat while DS aged 7 ran around playing on the equipment and making friends. It gave him some freedom which he doesn’t get much of, he knew we were close to hand and we could keep a gentle eye on proceedings without having to entertain him.
The rest of the facilities were fab, but this is one thing I would love to get again on holiday next year, but isn’t mentioned in the brochures.
The South Beach Cafe at Devon Cliffs has a playground next to it which would be visible from some of the seating areabut obv is only just along to coast from Ladram Bay so you might be looking further afield! The cafe is absolutely lovely though, top of the cliff, views to die for etc.
