CRUMBLING CLIFFS COULD FALL AWAY UNDER YOUR FEET

This is particularly obvious at Birling Gap, where cracks have formed along the cliffs. Also, there is currently no access via the steps from the beach at the Seven Sisters Country Park, so make sure you're aware that you could end up being cut off by the incoming tide.
Remember, if you do get into difficulty, or spot someone who might be in trouble, call 999 and ask for the Coastguard.
