You step onto the quay at Howth as sea wind trims the air; gulls wheel and the harbor murmurs around the hull. The boat slips past the stubby promontory of Howth Head, the Baily Lighthouse rising like a white word against basalt cliffs, then arcs across Dublin Bay toward the elegant sweep of Dún Laoghaire pier.

Dress in layers
Wind off the bay can make temperatures feel several degrees colder; a windproof layer and hat are useful even in summer.
Arrive early for parking
Howth fills quickly—allow 30 minutes to find a spot or use public transport to avoid stress before boarding.
Bring seasickness remedies
If you’re prone to motion sickness, take medication or use acupressure bands before departure; crossings can be choppy.
Choose your side for photos
For the best views of Dalkey Island and the Kish Lighthouse, sit starboard when departing Howth; daylight and weather will affect visibility.
Waterproof windproof jacket
Shields you from bay spray and the strong sea wind common on this route.
Layered clothing
Quickly adapt to changing temperatures on deck versus in sheltered areas.
Camera or smartphone with a strap
Capture lighthouses, cliffs and islands—use a strap to secure gear on a moving boat.
