Here is a tip, don't bother unless you can guarantee good weather. Thats 3 we have met that decided that a train home is the best option. Week ends are a pain , campings booked up and if the weather turns good luck finding accommodation under 130 euro. Finding that its glamping and campervan where the money is and as a result fewer tent campings. Yesterday a cyclist left the camping only to return , weather was bad and decided that it was impossible to hit the next camping and another turned up at 1 pm as he had enough. Was getting fed up not seeing the views hedges everywhere in places. The Irish cyclists posting on the velo 1 web site are saying its been pushed through to boost tourism. Another downside is that drivers are also taking the velo 1 route sectionsas opposed to the Wild Atlantic Way as an alternative judging by the number plates.. Need more small campsites and places to stop ( dont think the the irish are into picnic sites) pub culture is fine but if out in the sticks a place to stop is good if its rain or a big wind. Not surprised that its taken 40 years to come back to Ireland , and thats only because the ferry from Spain looked like a good way to cycle home..Done about 1500 km and only 100 km of cycleway out of the 2 big cities.
