It’s pretty busy down there in most places. Campsites are busy and so are the beaches on a sunny day. Busy in most the Devon/Cornwall resorts. I’ve been working in North Cornwall and North Devon and noticed the traffic getting heavier. If you are heading to the beach with family then stock up and take all your own food and drink. Queues are getting crazy for burger vans, ice cream etc. If you are eating out then book well in advance. If I’m just having a look around the beaches and coves I head out early doors to miss the crowds.
