Getting Started: The Entrance to the Promenade
The main entrance gates are easy to find — they're right at the end of the seafront promenade. There's a small carpark nearby, and public toilets at the visitor centre just before you enter. The first section of the pier is the most sheltered. You'll pass a small café on your left (good for a tea break) and some informational plaques about the pier's history.
The path widens here, which means it's easier if you're walking with someone or if you use a walking stick. The gradient is almost imperceptible — you're barely noticing the slight incline that'll become more obvious further along. The sea is usually calmer on this stretch, especially on the sheltered side where the inner harbour sits.
Pro tip: Start your walk on a day with decent visibility. You'll want to see across the bay to Howth and the Dublin Mountains. Cloudy days are fine too, but the views really justify the effort on clearer days.
