Hello, this is a year late as I've only just found the question. Most East Coast areas ban dogs from 1 May to 30 September. West Beach, Newhaven is an exception. Look up Coast Radar for dog-friendly beaches.

There are a few P&D car parks on the way to Beachy Head. The main route is simply Beachy Head Road. You also have a P&D car park in The Beachy Head pub and restaurant. There is a regular bus from Eastbourne centre up to the location you are interested in, but as I'm a pensioner, I have my bus pass so get free travel. But I would think a return ticket would likely cost about £5-£6.

There are enough parking space at both car parks. Since I am a stranger living in Japan, I don't know the best route.

Both are beautiful. I personally preferred the cliffs of Moher (but seen from the more peaceful Hag's Head) but Beachy Head is less touristy and therefore less crowded, and still very dramatic. Check out photos of both and decide for yourself! :)

It was a £1 for the hour. I stayed 10 minutes but still paid the £1. Should have chanced the presence of a Parking Warden

We walked along the sea front from the strand hotel then walked up hill to view point and visitor centre then back to victorian tea rooms on pier and it was exactly 7 miles in total a beautiful walk with lovely views and if your used to walking it will be no problem for you well sign posted. hope you enjoy.

Beachy Head is fairly well signposted. If you head onto the A259 towards East Dean you will see signposts guiding you towards Beachy Head.
