We parked in the Buckle Car Park at the far end of the Marin Parade which is free and has public conveniences. Also its not far to walk to the Tide Mill ruins and nature reserve from here. But we went the other way and walked the length of Seaford Beach into town. The pebbles are tricky in places, especially on the slope down to the shore line, but once you are by the sea its very pleasant walking all the way to the Seaford museum in the tower, which is unfortunatel closed in these Covid times. Plenty of people utilising the beach and plenty of fishermen trying their luck. A very pleasant place for a stroll.
