Have a plan. If you want to take in this lighthouse located about 5 walking KM from Dublin City Center; have a plan. For Europeans walking 5 or 10K in a day may not be much but it's not normal for American tourists. Whilst it's easy enough to get a taxi from city center to get to the pier, unless you pay waiting time while you stroll out to the piers end, take in the scenery, and snap your selfies, it's not likely that there will be a a queue of taxis waiting to take you back to civilization.
Such was our predicament this past outing. What you realize all too fast is that you have to walk about 3 KM before the traffic is routine enough that there might be a cab passing by that you could hail. After about another 1/2 KM you are so close to city center that you feel like taking a taxi for the last bit would put you to shame. So having a plan for getting there and back is Key.
As for the light itself it's a great view of the harbor. We saw two gigantic ships come in while we were out there. The walking path is pretty well flat with the stone treads running perpendicular to travel so your footing should be good over most of the span. I would even think a person could amble along with the use of a cane or walking stick as long they had the endurance.
What's not to be underestimated is the wind. Because the chance of a shower in Ireland seems to be ever present, having and umbrella by your side seems logical. But be forewarned any umbrella opened up while on the pier is simply a gift to the Irish Sea, and eventually The Queen, I assume.
If you a fan of seeing these relics to nautical navigation, Poolbeg is worth the walk, and maybe worth the loss of an umbrella. Nothing is worth the glowering look of your spouse at around the her 6th KM of walking because you didn't have a plan.
BTW, Continually encouraging her by saying "You're doing great, we are almost there." isn't a plan. read more
