•Get some fresh air along Dublin Bay•The dramatic vistas on the scenic four-mile hike are worth the trip•Finish off with a delicious vegetarian, organic, seasonal feastThe Dart train, the suburban rail line that runs along Dublin Bay, is a perfect way to get to the coastal villages just outside the city. The nearest station to the hotel is Grand Canal Dock, a short cab ride or 20-minute walk northeast along the edge of St. Stephen’s Green and through Merrion Square. Catch the 40-minute train south to Bray to do the cliff walk, which starts at the bandstand on the promenade, for knockout views of the bay (the tourist office on Main Street should have a map of the route). The four-mile walk takes about two hours and winds along the hillside, passing spots with an interesting history such as the Brandy Hole, which was notorious for smugglers, and a medieval church. On a clear day you can even see the mountain peaks of Wales across the Irish Sea from Bray Head. Look out for the wild roses, heather, and honeysuckle that grow in the rocky soil, and you might spot dolphins and basking sharks in the deep-blue water. The route ends in the harbor of Greystones village, with its colorful houses and sandy beach, where you can keep the healthy buzz going with lunch at the vegetarian café The Happy Pear. Run by identical-twin brothers, this bright and homey place is widely known for its organic, seasonal, and superfood-packed dishes (pumpkin, bean, and coconut stew; raw-chocolate bars; smoothies and juices; Happy Pear house roasted coffee). To plug into their natural lifestyle for yourself, sign up for one of their healthy-living courses, which include cooking demonstrations. Catch the Dart back to the city from Greystones station. The Cliff Walk is 40 minutes south of Dublin, in Bray. You can get the Dart train from Tara Street Station in the center of town. You’ll find the Happy Pear in Greystones, at the end of the Cliff Walk.CLIFF WALK: bray.ie/cliff-walk-bray​THE HAPPY PEAR: Church Rd.; +353-(0)1-287-3655; thehappypear.ie
