We plan to fly to London and then would like to fly to Shannon, Ireland. I would like to set up local tour guides for surrounding area sites….Cliffs of Moher, Ring of Kerry and etc. I have found week or more but only have 3/4 days. Do you know a travel agency or how to contact? Maybe stay in Galway? Thanks

Galway is an excellent base for day trips. From there you can easily visit the Cliffs of Moher, one of the Aran Islands, and the beautiful Connemara region. The Ring of Kerry would be a too far, but if you have only 3 or 4 days, I would suggest skipping that tour, and choosing one of those I've mentioned.

When we visited this area, we had a rental car, but there are many good local tour companies. You can Google "local tour companies Galway" to see a good selection. Here is one company I found, which has small group tours to all the places I mentioned, and more besides.

As I said, I have no personal experience of this company, but they are highly rated. Maybe someone else will have a recommendation.

I would spend one day exploring Galway, either on your own or with a walking tour.
