ballintoy is good, see pic
leave it until daytrippers leave, traffic can be wild.
toilets open all night
2 water taps front of toilet block for fresh water
good cafe for breakfast and snacks
if you do go early it is unlikely you can park at waters edge cos of daytrippers, park in car park behind toilets until most of daytrippers leave then move forward, great view !!
also mcginns pub,(carrickarede hotel) on main road before ballintoy, buy drinks or meal in the pub, park in rear car park, mccni overnight stop.
