Visit the Batts Rock cairns Have you ever thought to add a rock to the cairns? Have no clue what is a cairn? Grab your phone, Google and head to Batts Rock. Take care not to collapse or topple any of the beautiful creations. P.S. Wear your swimsuit and get a dip or do a little exercise as well. Adding your rock to the cairn creations is just for a little razzle-dazzle of course, to break up the monotony of your beach exercise hours. Remember the beach hours are between 6am and 9am or 3pm and 6pm. 3. East coast drives (to go the beach, or to a restaurant along that stretch)
