The appeal of Wicklow is its setting: gardens, lakes, woodland and mountains that make a stunning backdrop for photographs in any season. Many venues are country estates and houses offered on an exclusive-use basis, so you and your guests often have the whole place to yourselves for the day.
Because Wicklow is a destination county for many couples, accommodation is the main thing to plan: check how many rooms the venue has and what is nearby for the rest of your guests, and consider a coach from Dublin if many people are travelling. Outdoor ceremony options are common here, so always ask about a wet-weather plan.
