The Bray to Greystones Cliffwalk is a fantastic walk along the coast. There is a well kept path that is quite popular. It can be walked in both directions but if you only fancy going one way just take the DART back. We parked in Bray, walked to Greystones and got the DART back. From the Bray side it starts just after the Bray Head Hotel. Parking is limited here so grab some parking along the beach.
