Howth is a small town 14km (9 mi) northeast of Dublin city centre (still marked by 18th-century milestones). It is located on a peninsula closing Dublin's bay. It is most beautiful in Aug/Sept when the heather bathes the cliffs in red.The main visual feature of Howth (pronounced hohth ) is its harbour with fishing and pleasure vessels and a wharf lined with a number of seafood restaurants.Howth is home to a handful of Irish celebrities including Gay Byrne and Dolores O'Riordan. Walking the cliff walk or climbing the Ben of Howth, a 561 ft (171 m) high hill on Howth Head, on a fine day is well worth your time. Although the water may be too cold to enjoy a swim, Howth has a small stretch of beach that has a beautiful view of mountains in the distance. The affluent suburb of Sutton is located on the western part of Howth Head and boasts a scenic seaside walk featuring a Martello Tower and numerous lavish seaside homes.
